Two Google plans that could make open source code more secure

Malwarebytes - Fri, 06/18/2021 - 13:41

Recently Google announced that it will fund the further development of Rust. Rust is a low-level programming language that is designed to be more memory secure than other popular programming languages, such as C.

Google has also proposed an end-to-end framework for supply chain integrity which it has dubbed Supply chain Levels for Software Artifacts (SLSA).

Rust in Linux

Google’s investment in Rust will take the form of a contract for Miguel Ojeda, who’s worked on programming language security, to write software in Rust for the Linux kernel. Adding Rust modules to the Linux kernel could improve security for phones, computers and servers, because the Linux kernel is used in all the different Linux distributions, and it is also the core kernel for Android, ChromeOS, and many embedded systems. Android already supports the Rust programming language for developing the OS itself.

Rust is already is a favorite language among programmers and the Rust for Linux community has already started adding support for the language to the Linux kernel build system. Traditionally, kernel programming was largely done in C, which has been around since 1972 and is more prone to some classes of security errors than contemporary programming languages.

The goal of the project is not to replace all the existing Linux code but rather to improve selective and new parts. Josh Aas, who runs ISRG‘s Prossimo project, plans to focus on certain security-critical components and drivers. The Prossimo Project is what Ojeda has been working on.

Memory secure

The density of memory safety bugs in the Linux kernel is already quite low due to high code quality, high standards of code review, and carefully implemented safeguards. However, memory safety bugs do still occur on a regular bases. On Android, vulnerabilities in the kernel are generally considered high-severity because they can result in a security model bypass due to the privileged mode that the kernel runs in.

Secure coding is something that every programmer wants to do, but what really makes the difference is making it easy to accomplish. And that is what Rust has the potential to do.

SLSA

The goal of SLSA (“Salsa”) is to improve code integrity, particularly open source code, making it more resilient to supply chain attacks. It is inspired by Google’s internal “Binary Authorization for Borg” process which has been in use for the past 8+ years and is mandatory for all of Google’s production workloads.

The SLSA framework will be designed to safeguard source integrity and build integrity. It should provide end-users with the ability to check the provenance of any code they’re installing, so they can tell if it has been tampered with.

SLSA consists of four levels, with SLSA 4 representing the ideal end state. The SLSA level will tell the end-user whether the source, build, provenance, and security aspects meet a certain standard.

Bringing secure code to the end user

Starting with a secure low level programming language and safeguarding that security until it reaches the end user sounds like a very good plan. But it will certainly not be achieved in a short span of time. Google sees adding a second, more memory secure, programming language to the Linux kernel as an opportunity to adopt best practices in terms of documentation and uniformity right away. The contract with Miguel Ojeda has the duration of one year, which certainly will be aimed at tackling the most elementary obstacles on the road to a secure kernel. If they reach the level where it is easier to add Rust elements to the kernel than it is to keep going in C, they will have made an important step.

Since many servers hosting software on the internet are running on Linux, improving the security of the OS of those servers can be a first step in the road to more secure and easy to verify software.

But getting the industry to accept a standard that provides the end-user with some sort of option to compare the security level of software will be an even bigger struggle. Unless some sort of legislation is introduced to enforce and monitor such a standard. But as we have seen in the past with bills trying to regulate the safety of IoT devices, getting governments to agree on the requirements they want vendors to meet, let alone to adapt an entire framework could prove to be a gargantuan task.

It will likely be left to developers who want to do the right thing to adopt the standard. Although many likely will, history suggests we generally get whatever level of security the path of least resistance leads to. That’s why making it easy for kernel developers to use Rust is so important, after all.

Polazert Trojan using poisoned Google Search results to spread

Malwarebytes - Thu, 06/17/2021 - 18:41

Trojan.Polazert aka SolarMarker has gone back and fine-tuned an old tactic known as SEO-poisoning to plant their Remote Access Trojan (RAT) on as many systems as possible. This RAT runs in memory and is used by attackers to install additional malware on affected systems.

Trojan.Polazert

Trojan.Polazert is specifically designed to steal credentials from browsers and provide an attacker with a backdoor that allows them to further compromise infected systems. To achieve this, collected data is sent to a C&C server. To gain persistence on an infected system it adds shortcuts to the Startup folder and changes existing shortcuts.

Distribution

According to Microsoft Security Intelligence, attackers have started using PDF files full of keywords that have a high SEO ranking, so that their links show up prominently in search results. Once victims have downloaded the PDF file they thought they were looking for, they are prompted to download another document that supposedly contains the information they set out to find. Instead of getting the coveted document they are redirected to through multiple sites to end up at a page where they download the Polazert Trojan.

The attack works by using PDF documents designed to rank on search results. To achieve this, attackers padded these documents with >10 pages of keywords on a wide range of topics, from “insurance form” and “acceptance of contract” to “how to join in SQL” and “math answers”.

— Microsoft Security Intelligence (@MsftSecIntel) June 11, 2021

In the past this threat actor used to flood search results with more than 100,000 websites claiming to offer free office forms and document templates. All with the same end-result, a download of the RAT. The malicious website serves up an executable disguised as a pdf document or a word document.

As you might expect, the attackers used cheap, scalable Cloud hosting like Amazon Web Services (AWS) and Google Sites to host their malicious PDFs.

SEO poisoning

SEO is short for Search Engine Optimization and it is a marketing strategy that is designed to make sure that your web pages are found if people search for certain keywords that are relevant to your business. The ranking of a page in Google’s search results is based on a huge array of factors, but two of the core principles are what the page is about, and the page’s reputation.

A PDF will be stuffed with keywords designed to convince Google its about something very specific that people will be searching for. To target lots of different searches, they’ll need lots of different, narrowly-focussed PDFs.

The reputation of a page is calculated in part by using the number of inbound links pointing to it. Links from pages about the same subject, that themselves have strong reputations, have a greater effect. Typically, threat actors can leverage a large amount of pages to create inbound links.

Lazy crooks that don’t want to put in the work link building, or those that can’t afford to hire someone, or those put off by heavy competition for keywords, may consider buying incoming links from an underground market vendor. These threat actors control a multitude of compromised sites that they can use to post links on. Another method that SEO poisoners may use is to build links is spam forums, with the help of spambots.

What they don’t use, is social media. Contrary to popular belief, posting links on social media like Facebook and Twitter does not help to improve a page’s SEO. The links on social media are “nofollow” links, and Google’s bots will not follow them or add them to the tally of incoming links.

Recognizing this threat

While it is not uncommon to be shown pdf files when you are using search engines, but it is advisable to scrutinize their content. Apart from the first page the stuffed PDF files look empty, but a closer look reveals their content.

The text was hidden by using the same text and background color

It is also worth bearing in mind that aside from being used in SEO poisoning campaigns like this, malicious PDFs can also be used to trigger bugs in reader software, and there are no shortage of bugs.

The first page of the PDF file showcased by Microsoft Security Intelligence offers users a choice of a PDF download or a Word document download, under the heading “Select Download Format”. Or, in other words, would you like your RAT as a PDF or a DOC?

It is certainly feasible that this threat actor will change tactics again, but being aware of their current tactics may help you thwart their next attempt.

Stay safe, everyone!

The 6 best Chrome extensions for privacy and security

Malwarebytes - Thu, 06/17/2021 - 13:25

While searching for security- and privacy-improving extensions, users may end up installing an extension that is counterproductive to their goals. To help our readers I have compiled a list of Chrome extensions that can actually help you improve your online privacy and security.

Our regular readers have seen me post various warnings about malicious Chrome extensions. The fact that these malicious extensions exist doesn’t mean it’s not safe to install extensions at all. Some extensions will even improve security and privacy. So, for a change, I am going to highlight a few of them, by sharing my personal favourites.

“How come you are focusing on Chrome?” you may ask. Well, Chrome is the most popular browser in the world, by far. It has a market share hovering around 65%. This popularity among users also makes it a popular target for advertisers and malicious actors. I would not dare say that Chrome is less secure than the other popular browsers. All of the modern browsers are highly complex, sophisticated pieces of software that offer a substantial target to attackers, and all of them take security seriously.

Although there certainly are better choices for privacy-oriented users, but that’s another topic for another day.

The 6 best extensions

In my list I have tried to include extensions that complement each other rather than ones that compete against each other by doing the same job. Obviously there will be some overlap, especially where it comes to ad and tracker blocking. Where I have listed that extensions are available for Chrome you will find that they are also available for most Chromium-based browsers like, for example, Vivaldi and Brave. Extensions are listed in no particular order.

Malwarebytes Browser Guard

Works with: Chrome, Edge, and Firefox.

Malwarebytes Browser Guard not only blocks some advertisements and trackers, it also stops in-browser cryptojackers (unwanted cryptocurrency miners), and it also uses an extended version of the Malwarebytes Premium blocklist that will stop malicious sites from loading—including sites that are involved in tech support scams. As a bonus, blocking unwanted content can speed up your browsing up to four times.

HTTPS Everywhere

Works with: Chrome, Edge, Firefox, and Opera. It is already included in Tor.

HTTPS Everywhere ensures that you always connect to sites using secure HTTPS encryption instead of HTTP. It forces sites to use HTTPS if they offer it can block access to sites that don’t. This protects information like logins and personal data when it’s travelling between your computer and the website you’re using.

Many sites on the web now offer HTTPS, but it may not be compulsory, or the default, and your connection can easily be downgraded to HTTP if you click on a link that somebody forgot to add the “s” to. The HTTPS Everywhere extension fixes these problems by rewriting URLs so they always use https://.

Ghostery

Works with: Chrome, Edge, Firefox, and Opera.

The free version of Ghostery blocks the ads and trackers that can follow you around the web, creating a profile of who you are and where you go. The Plus version offers additional application ad blocking.

uBlock Origin

Works with: Chrome, Safari, Opera, and Firefox.

uBlock will block advertisements, including video ads, as well as trackers. It also functions as a pop-up blocker and helps protect against some forms of malware.

1Password

Works with: Chrome, Edge, and Firefox.

1Password is a password manager that will create, store, and enter strong passwords for you. Unfortunately the free version of 1Password has a short life span, but the paid version is really worth having, not least because it can import the passwords stored in your browser. The autofill option will save you a lot of time and offers some protection from phishing attacks.

Click&Clean

Works with: Chrome, Edge, and Firefox. Some functionality requires the Click&Clean Host.

The Click&Clean extension helps you clean up your private browsing data. Modern browsers try to make browsing as quick and easy as possible, and that means remembering a lot of stuff, including a cache of pages you’ve visited, your search history, data you’ve entered into forms, cookies, and more. Click&Clean gives you an easy way to clear out the bits you don’t want to hold on to.

But I like the so-and-so extension better!

Don’t let me stop you from using the extensions that you are used to. Some of these extensions do have competitors that are just as good and you might like them better. But these are my personal choices and in my experience they work well together.

This is only here to help those looking for new security and privacy related Chrome extensions find something trustworthy. Unfortunately, looking for this type of extensions will sometimes lead to extensions that do the exact opposite of what they promise. For example, we have seen a lot of extensions that promise to perform more secure or privates searches, but all they do is redirect your searches somewhere else, often adding some advertisements as well.

What is the best antivirus extension for Chrome?

This is a question I get asked a lot and the answer is not that simple. Or actually it is. There are no antivirus extensions for Chrome in the traditional sense. Some of the extensions in my list will stop malware from entering your system, but removal and protection are two different things. There are some browser extensions that can remove malicious extensions from the browser they are installed on, but the anti-malware solution you are using should have no problem doing that. In fact, it will very likely do it better. Extensions that claim to clean anything more than the browser are to be distrusted.

Stay safe, everyone!

Clop stopped? Ransomware gang loses Tesla and other treasures in police raid

Malwarebytes - Wed, 06/16/2021 - 19:36

Ukrainian law enforcement officials announced Wednesday that they had arrested several individuals involved in criminal activity committed by the Clop ransomware gang, a cybercriminal gang that helped popularize the “double extortion” model of not only threatening to encrypt a victim’s files, but also threatening to release confidential data that was stolen in an earlier breach.

According to a press release issued by Ukrainian authorities, law enforcement officials also shut down infrastructure that was used to spread the cybercrime gang’s ransomware, which was first spotted in February of 2019 as a new variant of the Cryptomix family.  

“Together, law enforcement has managed to shut down the infrastructure from which the virus spreads and block channels for legalizing criminally acquired cryptocurrencies,” the press release reportedly said, according to a translation from BleepingComputer. “Law enforcement officers conducted 21 searches in the capital and Kyiv region, in the homes of the defendants, and in their cars.”

Ukrainian law enforcement reportedly said that the Clop ransomware gang has caused roughly $500 million in financial damages, and that the individuals arrested could face up to eight years in prison.

As seen in a video of the arrests, Ukrainian officers were aided by investigators from South Korea. BleepingComputer reported that the arrest effort also included coordination from officials in the United States. In the video, nearly $30,000 are laid out in the floor, in $100 bills, and several cars, including a Mercedes Benz, a Tesla, and a Lexus, are taken away.

The international coordination effort represents at least the second time this year that countries have come together to fight cybercrime. In January, a coalition of countries collaborating through Europol helped take down Emotet by also attacking its infrastructure.

But whereas the Emotet takedown seems to have caused a significant disruption to that cyberthreat, the arrests made against Clop could present a smaller roadblock. That’s because, according to the cybersecurity company Intel 471, none of the actual members of the Clop ransomware gang were caught.

Instead, the arrests involved money launderers, Intel 471 said.

“The law enforcement raids in Ukraine associated with CLOP ransomware were limited to the cash-out/money laundering side of CLOP’s business only,” Intel 471 told BleepingComputer. “We do not believe that any core actors behind CLOP were apprehended and we believe they are probably living in Russia.”

The arrests also represent the second time in weeks that authorities have targeted a cybercrime gang by following the money. In early June, the US Department of Justice announced that it had recovered the majority of the ransom payment made by Colonial Pipeline to its attackers, the cybercriminal group called Darkside. By tracking the ransomware payment through the public Bitcoin ledger, the Department of Justice and the FBI managed to retrieve 63.7 bitcoins.

Cryptocurrencies have long been abused to fund cybercrime, and, perhaps with the recent retrieval of Colonial Pipeline’s ransom payment, that intersection will continue to be closely scrutinized. If so, it would fall in line with the Ransomware Task Force’s recommendations made in April, which suggested that governments lean further into regulating cryptocurrency.

While Clop was not particularly active last year—it did not enter our top 10 malware threats for businesses or consumers in 2020—the operators behind the ransomware still found ways to squeeze their victims. Inspired last year by the ransomware group Maze, Clop infiltrated company networks to steal sensitive data and then demanded that those organizations pay a ransom to keep the data secret. But this year, Clop refined that tactic by targeting corporate executives’ machines, hoping that executives would have more access to sensitive files and data. The idea was simple: Better access to sensitive data, better chance that a victim will pay to keep that data from being published.

As of Wednesday afternoon, according to BleepingComputer, Clop’s Tor payment site and data leak site were still operational.

Jail for consultant who scraped colossal trove of Alibaba customer data

Malwarebytes - Wed, 06/16/2021 - 15:31

A billion data points, including the usernames and mobile phone numbers of customers have been siphoned off Alibaba websites by a web crawler. The information has reached us about a week after a court ruling in the case.

The court ruling

A central Chinese court has ruled that an employee of a consultancy firm was guilty of gathering more than a billion data items of Taobao, users since 2019. (Taobao is the consumer-to-consumer platform on Alibaba’s sites.) The court imposed jail terms of more than three years, alongside fines totalling 450,000 yuan (approximately $70,000). Apparently the consultancy firm helped Taobao with merchants on Alibaba’s Taobao online mall. And their employee was using his access to the data to serve other clients.

Alibaba

Alibaba is one of the biggest online marketplaces in the world. Originally Alibaba.com started out as a business-to-business (B2B) platform, but with the foundation of Taobao it expanded into the consumer marketplace.

Alibaba’s consumer businesses annual active consumers on its China retail marketplaces reached 811 million for the twelve months that ended March 31, 2021, increasing from 779 million at the last quarter of 2020.

Like its nearest US equivalent, Amazon, the company also runs cloud services, a payment service (Alipay), and is active in digital media. In 2005 it started a close cooperation with Yahoo!

Alibaba statement

None of the customer data was sold and Alibaba’s users didn’t incur financial losses from the episode, the company said in a statement.

“Taobao devotes substantial resources to combat unauthorized scraping on our platform, as data privacy and security is of utmost importance. We have proactively discovered and addressed this unauthorized scraping. We will continue to work with law enforcement to defend and protect the interests of our users and partners.”

Web scraping

Although some media will call this a data leak or breach, web scraping is a different beast altogether. We did not expect to see the scale of Facebook’s data scrape of 533 million users to be “beaten” anytime soon, but a few months later and here we are. In Facebook’s case the scraping was possible because of a vulnerability that Facebook patched in 2019. In Alibaba’s case the scraping was enabled because the employee of the consultancy firm had full access to a part of the online infrastructure.

And while most types of web scrapers are perfectly fine, for example scrapers that help you find the best price for a product, the question is whether it is OK to scrape websites for personal data. While website users may have given consent to use some of their data for marketing purposes, is it fair to expect that they can anticipate how much information about them is available to potential scrapers, or how that data becomes something entirely different when it’s part of a billion-record data set, or when it’s combined with other information about them that makes their personal life pretty much an open book?

Chinese restrictions

The news about this court ruling comes at a keen moment for China as it recently announced it wants to tighten restrictions on the information gathering by internet giants like Alibaba, Tencent, and others. Last March, the Chinese government published new standards for the collection of personal data, specifically defining “necessary” data collection.

Among limitations like stopping app providers from collecting a broad range of data under a bundled consent model, the new data protection rules force Chinese companies to obtain government permission before transferring data outside of the country and grant individuals a right to access personal information held by data processors.

While we applaud these initiatives to protect user data-privacy, in China’s case it feels like a matter of “do as I say, not as I do.”

Twitter takes aim at the chaos, clutter and trolls with new feature concepts

Malwarebytes - Wed, 06/16/2021 - 15:02

Twitter is potentially looking to add some new features to combat specific forms of abuse and / or aggravation on the platform. They’re still at the design stage, but they’re asking for feedback and it seems this will happen down the line. With that in mind, let’s take a look at what they’re up to.

Unmention yourself

Unmention yourself

I want to make it easier to untag yourself from a Tweet or conversation you don't want to be involved in.

Just pick “Unmention yourself from this conversation” from the more info menu and the link to your profile will be removed. pic.twitter.com/nfHIyReE9f

— Dominic Camozzi (@_dcrc_) June 14, 2021

This slightly clunky term is based around the Twitter-specific concept of “my mentions”. In other words, your reply tab which is surely filled with wonderful things. On the off chance that it isn’t, this can help. Twitter conversations tend to draw people in like inexorable whirlpools of terror. Perhaps someone you know tagged you into a random conversation because they thought you may be interested. That’s usually fine. It’s not fine when tagging you in is to encourage abuse.

Maybe you commented on a random news story and now everyone’s yelling at you. Perhaps trolls deliberately dropped you into a massive crowd of other trolls who are all also yelling at you. It’s possible you began the conversation yourself, and now everyone in your replies is yelling all day long.

Whatever your pickle, this is the fix. Currently, there is no way to remove yourself from a conversation. “Please untag me”, goes the cry of those in Twitter purgatory. “Oh no, you haven’t untagged me and I’m still being copied in to dozens of awful messages” goes the second cry. “It’s been 8 hours and a thread which was originally about cakes is now something to do with World War 2. Please help” goes the final cry before the phone is hurled out of the window.

When muting isn’t a solution

The current solution to this is the mute option. In theory, you hit the “mute conversation” button and it’s removed from view. It doesn’t matter how many replies it gets, or how many people send you a message: they’re all invisible, forever.

That’s the theory. In practice, the mute option is notoriously buggy. If you have a spider phobia, you can mute the word spider. It doesn’t mean the word won’t randomly break through the mute and show you some sort of horrendous spider content. If you mute a user who annoys you, Twitter may still randomly show you future replies or tweets. Mute a conversation? You can try. If you’re in a very viral conversation (whether you started it or joined later), these too will occasionally break the mute and pop back into your timeline.

Being able to “unmention” yourself, though? This is an additional string in the “please leave me alone” bow. If you’re able to drag yourself out of a thread, it’s possible the conversation will be gone for good. There’s an additional benefit here over muting. When you mute, it’s supposedly gone forever. This isn’t helpful if there are parts of the discussion you may want to revisit at a later date. If they can get this working, it promises to be very useful while avoiding the problem of having your replies tab hammered by unwanted noise.

Unmention individuals

Notifications

Going further, if someone you don’t follow @ mentions you, you’ll get a special notification. If you unmention yourself from there, the Tweet author will not be able to mention you again. pic.twitter.com/RTFBEnkPFf

— Dominic Camozzi (@_dcrc_) June 14, 2021

If you’re fed up with people jumping in to send you nasty messages, you’ll be able to prevent them tagging you in ever again with this proposed feature. The moment they start typing out your username, they’ll be told that [username] can’t be “mentioned” (sent a message). The image shows the potential nasty person sending a message directly, like so:

@[username] did you know that thing you like is actually really awful? You should! And now I’m telling you all about how much I hate it! Hooray!

 It’s not clear if this would work for dropping someone into the middle of a message like:

You know what I hate? Those things that @[username] enjoys. Wow, are those some really terrible things that you like! Wow! Terrible!

Currently, the only option is to block. Blocking stops someone from sending you messages directly, but it doesn’t prevent the “drop someone’s username into the middle of a tweet” activity outlined above. As a result, they can still drive bad traffic to the victim. Stopping people from doing this would be a very useful thing indeed.

Unmention individuals, part 2

This doesn’t seem particularly different from the last option. The only real difference I can see is that you can essentially shut down people’s ability to mention you for 1, 3, or 7 days. A good option for when your replies section is completely out of hand.

Control mass mentions

Getting a little TOO much attention? I want to make it easier to address that in 3 ways.

1️⃣ Get notified when you’re getting a lot of mentions
2️⃣ Review those Tweets
3️⃣ Change settings to stop the situation from escalating further pic.twitter.com/CL43INsMky

— Dominic Camozzi (@_dcrc_) June 14, 2021

Twitter was initially designed for letting small groups of friends know what you were up to via mobile. It’s morphed into a discussion platform over the years. On any given day, there’s millions of conversations about any subject you care to mention. The only problem is, it’s frequently unsuited to said conversations taking place because of, among other things, a lack of controls over who’s dropping you in or out of discussions, and an inability to keep your replies free from harm.

The moment you do a good Tweet and it goes viral, the platform is essentially unusable for a few days until things calm down. You’re DDoS’ing yourself off Twitter by virtue of being good at it. Even verified accounts, who have additional options regular users don’t have, find it impossible to get around this. The moment dozens, hundreds, or thousands of replies appear all at once? Good luck, see you in three days.

This is similar to the above proposed setting, except it tells you how many times you’ve been mentioned in a short space of time and then allows you to specify who, exactly, can mention you.

Closing thoughts on the proposed changes

As you can see, Twitter is trying to add some nuance to dealing with abuse and clutter generally. My sense here is that some sorely needed flexibility is on the way; we just need to see how long it takes to implement.

There’s still a few areas in all this that don’t seem to be addressed yet.

For example, Twitter allows you to restrict how you can reply to tweets already. For example, I can set it to followers only, or people who I follow back. If someone dislikes your tweet, they’ll bypass restrictions by quote tweeting you. I don’t know if the new additions would prevent that from being possible.

Either way, expect to see more wrinkles ironed out over the coming weeks / months. Let’s see if Twitter can finally plug some of the more creative ways people have of causing chaos on the social media platform.

Windows 10 to retire in four years (or 52 Patch Tuesdays, in sysadmin years)

Malwarebytes - Tue, 06/15/2021 - 15:41

Microsoft will terminate support for Windows 10 Home and Pro on 14 October 2025, a decade after the original Windows 10 was brought to market. Although some may claim that a Microsoft document has been “quietly edited” over the weekend to reflect this “sudden change”, this reveal isn’t new. In fact, based on a Wayback Machine screen capture of the same page, Windows Central has pointed out that this reveal has been on the Microsoft page since September 2020.

Nevertheless, this renewed interest on Windows 10 has come almost three weeks after the Microsoft Build 2021 event in late May, where Microsoft CEO Satya Nadella teased of something big in the works: a “next generation of Windows” (Hint: It won’t be called Windows 11). Furthermore, this end-of-life cycle reveal has happened at least a week before a new Windows digital event on 24 June 2021.

And soon we will share one of the most significant updates to Windows of the past decade to unlock greater economic opportunity for developers and creators. I’ve been selfhosting it over the past several months, and I’m incredibly excited about the next generation of Windows. Our promise to you is this: we will create more opportunity for every Windows developer today and welcome every creator who is looking for the most innovative, new, open platform to build and distribute and monetize applications. We look forward to sharing more very soon.

Transcription of Nadella’s keynote, reproduced from Windows Central, during the Build 2021 event

Microsoft hasn’t hinted on when this new OS will be revealed to the public, much less made available in the market, but Nadella admitted that he has been testing it for months. We don’t know what it will contain, but Windows is still the platform of choice for most businesses, and therefore the platform of choice for most malware—including the most dangerous forms, like ransomware—so we’d be surprised if it doesn’t include something designed to tackle that head on.

The company also expects the transition from the would-be-retired Windows 10 to the new desktop OS would take around four years. History suggests that’s optimistic. Windows XP reached the end of its life seven years ago.

This matters, because the end of life means an end of patches, and a progressively worsening security situation for any organisations that don’t migrate in time. The time to start planning is now.

And if there is anything we’ve learned about end-of-life cycles and support, it’s this: Scammers and fraudsters have made it a point to use news like this to lure potential victims into either downloading malware disguised as a legitimate file or to steal pertinent information and credentials. So, while we prepare for this transition, let’s not forget to also keep our eyes open. Stay informed, and stay safe!

Patch now! Apple fixes in-the-wild iPhone vulnerabilities

Malwarebytes - Tue, 06/15/2021 - 14:35

Apple has fixed two vulnerabilities in Safari’s WebKit component, announcing it is aware of a report that they may have been actively exploited. Both vulnerabilities could be abused by maliciously crafted web content that could lead to arbitrary code execution: In other words, the bugs let rogue websites do things on your phone without your permission.

Letting users of its products know that vulnerabilities are being actively exploited is a new approach for Apple. It has always been reluctant to provide much context in its security bulletins and only recently started adding information about whether vulnerabilities are being used in the wild.

WebKit

WebKit is the web browser engine used by Safari, Mail, App Store, and many other apps on macOS, iOS, and Linux. The vulnerable WebKit version is available for: iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation). 

This is the 9th actively-exploited zero-day patched by Apple this year. Seven of them were related to WebKit. One was a GateKeeper bypass, and the other a TCC bypass. Gatekeeper is designed to ensure that only trusted software runs on your Mac, and Apple’s TCC  protection is built to safeguard privacy.

CVEs

Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. The two vulnerabilities that were reported to be abused in the wild are:

Both vulnerabilities have been submitted by an anonymous researcher. It is not known whether they were both submitted by the same researcher.

Memory corruption issue

Memory corruption bugs occur when a program’s memory is modified in a way that was not anticipated by the programmers. When used by an attacker, a memory corruption bug can become a serious security vulnerability that might allow an attacker to leak sensitive information or execute arbitrary code. The generic term “memory corruption” is often used to describe the consequences of writing to memory outside the bounds of a buffer, or to memory addresses that are invalid.

Use after free

Use-After-Free (UAF) is a vulnerability related to incorrect use of dynamic memory during program operation. If after freeing a memory location, a program does not clear the pointer to that memory, an attacker can use the error to hack the program. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code.

Apple

As is customary, Apple did not provide details on the zero-day attacks, which appear to be aimed at a range of older models of iPhones. It’s remarkable that Apple disclosed that these vulnerabilities are being used in the wild as this has not been its habit until recently.

“For our customers’ protection, Apple doesn’t disclose, discuss, or confirm security issues until an investigation has occurred and patches or releases are available. Recent releases are listed on the Apple security updates page.”

Waiting to disclose issues until a patch is available certainly makes sense, but keeping under wraps how serious an issue is, is a different case. Whether this new habit of letting customers know that vulnerabilities are actively being abused is here to stay remains unknown, but it brings Apple more inline with industry norms. From our perspective it is progress. Not in the least because it gives users a perspective into the urgency of getting the necessary patches.

Stay safe, everyone!

Another one bites the dust: Avaddon ransomware group shuts down operation

Malwarebytes - Mon, 06/14/2021 - 22:51

Are you seeing some pattern here?

In what could be a called “shocking news” on Friday, BleepingComputer revealed that the gang behind the Avaddon ransomware shut down its operations after releasing more than 2,000 decryption keys to the technology news site.

BleepingComputer claimed they received an anonymous tip purporting to be from the FBI, containing a password and a link to a password-protected ZIP file.

These are the three files in the ZIP file. which came directly from the Avaddon ransomware group. They contain the decryption keys, (Source: BleepingComputer)

If you may recall, Avaddon is a big game hunting (BGH), ransomware-as-a-service (RaaS) tool that the US Federal Bureau of Investigation (FBI) and the Australian Cyber Security Centre (ACSC) warned organizations about last month.

Malwarebytes detects this ransomware as Ransom.Avaddon.

Avaddon ransomware attack victims

While various sectors in Australia were noted to be particularly targeted, the Avaddon strain has been instrumental in the successful network compromise of the Asian division of the AXA Group, one of the biggest cyber insurance companies in the world. Avaddon threat actors were able to extract information about what appears to be client info: passports, bank account information, ID cards, contracts, fraud-related hospital files, and other medical reports containing sensitive data about patients, and more.

Coincidentally, this attack came close to a week after the insurance giant announced that it would cease covering customers in France who pay up after being attacked by ransomware. An insurance company refusing to cover for any monetary loss over a cyberattack will no doubt significantly increase the likelihood of victim companies refusing to cough up money to ransomware gangs.

Schepisi Communication, an Australia-based telecom service provider, was also hit by Avaddon last month after its platinum partner, Telstra, fell victim to a ransomware attack by the same group. The criminals claimed to have access to data of a large amount of SIM cards, mobile devices, contracts, and banking information to name a few. When the company refused to pay the demand, their official website was downed by distributed denial of service (DDoS) attacks, taking their website offline for several days.

Avaddon threat actors are also not one to shy away from going after organizations in the healthcare industry. According a threat report from eSentire, a leading Managed Detection and Response (MDR) service provider, Avaddon has targeted the Capital Medical Center in Washington, Bridgeway Senior Healthcare in New Jersey, and an intensive care online network.

A domino effect? Or a simple coincidence?

After DarkSide called it quits from the pressures of the US government following their attack against Colonial Pipeline, reading about Avaddon—considered to be a “second tier ransomware operator”—would make one think that there is cause for celebration. Indeed, this is a win and something we should be grateful for.

Let us not forget, however, that any time a ransomware gang decides to shut down, more gangs appear (If you’re on Twitter and follow several malware/ransomware hunters, you’ll agree).

It is also a known fact that ransomware actors have the habit of rebranding under the guise of shutting down—or to simply avoid US sanctions—so it won’t be far off to think that this is all a ruse. And speaking of sanctions, as of this writing, there is nothing that links Avaddon’s demise to the increased attention the US government has given ransomware groups lately. It’s likely then that this is all just part of the normal flow of events when groups give up from time to time. That said, this could be one of those wait-and-see scenarios.

Nonetheless, we welcome any ransomware gang quitting as good news. But perhaps, at the same time, we’re also left wondering: Is there a quiet chaos going on right now within and among the underground ransomware gangs? Will they start dropping like flies? Will we be left with our old, insecure ways if or when ransomware attacks do plummet?

Well, let’s wait and see.

Working from home? You’re probably being spied on

Malwarebytes - Mon, 06/14/2021 - 17:58

One year ago, as countless employees settled into new routines for working from home (WFH), a Reddit user shared a video online of a strange contraption: A wire coat hanger bent out of shape, one side gripping an external USB mouse, the other side latched onto an oscillating fan. As the fan swished left and then right, so, too, did the USB mouse.

What was the point? The device, the Reddit user suggested, was a low-tech defense against workplace surveillance.

WFH Tip #2: How to always appear online,” read the video’s title.

This laughable attempt to subvert digital workplace monitoring was a bit of a joke, but the video spotlighted an unfortunate reality facing WFH employees today. Rather than being trusted to accomplish their jobs out of physical view, a startling number of employees are being tracked and measured through privacy-invasive software which can surveil their web browsing habits, track their app usage, monitor their screen time—periodically capturing screen images—and even transcribe their phone calls.

The fascination with digital workplace surveillance software—sometimes called “bossware”—is increasing, according to a recent survey funded by ExpressVPN, in collaboration with Pollfish. Of the 2,000 employers surveyed, 57 percent “implemented employee monitoring software in the past six months.” Of those that had not deployed such software, 59 percent said they were “very or somewhat likely” to do so in the future.

But employers should caution themselves against likely pushback, as employees in the survey repeatedly expressed contempt for the tools and the behavior it enabled.

“It’s micro-management,” said one anonymous survey respondent, according to the key highlight report from ExpressVPN. “As long as my productivity is acceptable and my work is getting done, it shouldn’t matter how I pass the time while waiting for an active job to pick up.”

Employers can’t feign ignorance about this, either. According to the the ExpressVPN survey, while 78 percent of employers admitted to using employee monitoring software to track their employees, even more—83 percent—believe there are “ethical concerns” with that type of software.

The pandemic’s productivity panic

In the first months of the COVID-19 pandemic, as thousands of companies shifted to WFH models, a certain panic arose regarding potential, lowered productivity. The combination of removing workers from a potentially collaborative in-office environment, expecting them to simultaneously tackle childcare and work, and hoping they can manage the stress of a global pandemic, often led corporate leaders to believe that their employees’ productivity would slow to a crawl.

Those concerns, it appears, led to increased demand for digital workplace surveillance software.

According to reporting from Wired in October of last year:

“As working from home has flourished, so too has employee monitoring software. Programs such as Time Doctor, ActivTrak, Teramind and the dystopian-sounding StaffCop have all seen huge upticks in demand. Remote teams are now watched through their webcams via always-on video services like Sneek. In the office-free world, bosses can now clandestinely scan screenshots, login times and keystrokes at will to ensure their workforce is keeping its focus and productivity.”

The sentiments of employers captured in the ExpressVPN survey sound similar. As the survey authors wrote, “the biggest driver behind employers’ growing interest in surveillance is their uncertainty and unease about the status of their company and whether employees are doing what needs to be done to maintain overall business performance.”

That showed up in the data with the following numbers:

  • 74 percent of employers said “remote work makes them feel a lack of control over their business”
  • 57 percent “don’t trust their employees to work without in-person supervision”
  • 59 percent “don’t trust their employees to work without digital supervision”

Considering this broad, shared concern in potentially lowered activity, then, it is quite strange that survey after survey after survey have shown there is little truth to it.

When Microsoft commissioned KRC Research, Boston Consulting Group, and the Wharton School of the University of Pennsylvania to survey 9,000 respondents across Europe last August who started working in more hybrid and remote models, 39 percent said they felt equally productive, 34 percent said they felt somewhat more productive, and 10 percent said they felt significantly more productive.

When Mercer surveyed 800 employers last year, 94 percent said “productivity has remained the same or improved since employees began working remotely.”

And when Malwarebytes Labs asked 200 managers, directors, and C-suite executives in IT and cybersecurity roles across the United States about their biggest struggles with shifting to a WFH model, only 2.5 percent said they experienced “significantly lower” productivity.

The data is not there, but that does not seem to matter for the managers who are making the decision to surveil their employees. Instead, the decisions seem to be carried on intangible unease. In fact, according to the ExpressVPN survey, 69 percent of employers said they “feel uneasy about remote work because they can’t observe employees in person”

Well, what are the employees feeling?

Employee pushback

When employees know they are being surveilled, they do not just dislike it. They consider it damaging to their relationship with the employers.

  • 43 percent of employees said the use of these tools “is a violation of trust”
  • 28 percent said it “makes them feel unappreciated”
  • 26 percent said it “makes them feel resentment”

Further, 59 percent of employees reported feeling “stress and/or anxiety about their employer surveilling their online activity.” The reasons for that stress vary—from 41 percent wondering “whether they’re being watched” to 36 percent feeling “pressure to work longer hours in general. But, critically, 20 percent of employees said they “feel dehumanized as a result of workplace surveillance.”

These are heavy terms, and employers should recognize that when their employees begin to feel like this, they have a strong chance of losing them. According to the survey results, 54 percent of employees said “they’d be likely to quit if their employer and/or boss implement surveillance measures.”

But for the employees who will not quit, the picture is not any brighter. Instead, employers will likely find themselves fighting against employees who are subversively rolling out anti-surveillance measures that they either look up online or devise themselves (need we remember the Reddit user’s renegade partnership between their home fan and their USB mouse?). According to the survey, 31 percent of employees who know they are surveilled said they use “anti-surveillance software,” and 25 percent “researched hacks to fake online activity.”

Surprisingly, almost half of surveilled employees—49 percent—said they “pretended to be online while actually doing non-work activities.”

This is the pushback that employers can expect for voluntarily wrecking their employees’ trust. Remember, many employees reported feeling resentment about being surveilled. It stands to reason that an employee who resents their employer will have little qualms about tricking them, wasting their time, and half-assing it until they can find a new job.

After all, what’s the point of putting in professional work if you won’t be treated like a professional? The popularity on Reddit alone isn’t worth it.

How to delete your Instagram account

Malwarebytes - Mon, 06/14/2021 - 11:14

Although sharing your day’s highlights in snapshots and videos on Instagram can be entertaining, some people claim to feel happier after deleting their accounts. Consuming media tailor-made to make other people’s lifestyles appear alluring can be addictive for some and induce anxiety in others. Not only do people delete Instagram for their wellbeing, but they remove it for privacy concerns. Hackers, scammers, and stalkers can use the photo and video sharing social networking platform to target others, and Instagram is part of Facebook’s advertising panopticon.

For any of these reasons, a number of Instagram users decide to take a break from the platform at some point, either temporarily or permanently. If you do, remember that you will lose the following data permanently when you delete your Instagram account:

  • Profile
  • Photos
  • Videos
  • Comments
  • Likes
  • Followers

You can sign up with the same username again after deleting your Instagram account. However, this won’t be possible if someone else has created an account with the same username. Hypothetically, someone could impersonate you after you leave by creating an account with the same username. That’s why you may want to disable your account rather than delete it.

How do I disable my Instagram account temporarily?

To hide your account, profile, photos, comments, and likes, you can opt to disable your Instagram account instead of erasing it. Disabling it is easy and requires a web browser on a computer, tablet, or mobile phone. Unfortunately, you can’t use an Instagram app to disable Instagram.

  1. Log into your Instagram account from a web browser.
  2. Click your profile picture on the top right of the screen.
  3. Click Profile followed by Edit Profile.
  4. Find Temporarily disable my account on the bottom right after scrolling down.
  5. Pick an option from the drop-down menu that says Why are you disabling your account?
  6. Enter your password.
  7. Hit Temporarily Disable Account to hide your account until you’re ready to reactivate it.
How to download your Instagram data on a Computer, Android, or iPhone

You may want to back up your pictures, videos, and posts from Instagram before deleting your account. Once you delete your account, your media is irrecoverable. Here is how to get a copy of everything you’ve shared on Instagram:

  1. Click or tap your profile picture and then find Settings.
  2. Click Privacy and Security on a computer or tap Security on Android or iPhone.
  3. Click Request Download on a computer or tap Download Data on your mobile device.
  4. Enter your email address, Instagram account password and use the Request Download option.
  5. Wait for an email from Instagram titled Your Instagram Data. Instagram says that it can take up to 48 hours to send the email.
  6. Use the link in the email to download your data.
  7. You can contact Instagram directly if you’ve lost your username or password and need access to your data.
How do I delete my Instagram account on a computer?

Log into your Instagram account. Follow this link to get to the Delete your account page. Pick from one of the listed reasons explaining why you want to delete your account. Re-enter your password and delete your account for good.

How do I delete my Instagram account on my iPhone or Android device?

Deleting an Instagram account through a mobile app isn’t possible. You may find it easier to delete it on a computer and remove the mobile app. You can use the following steps, but they eventually lead you to a hyperlink on a web browser.

  1. Start the Instagram app on your phone.
  2. Tap the Profile icon.
  3. Go to the Profile page and tap Settings.
  4. Scroll down to Help Center and tap Basics.
  5. Hit Getting Started and then scroll through the options until you find Delete Your Account
  6. Select How do I delete my account and follow the hyperlink to your web browser.
  7. You may need to enter your Instagram password and choose a reason for deleting your account.
  8. Hit Permanently deactivate my account and then tap OK.
  9. Uninstall Instagram from your iPhone.
How do I make my Instagram account more secure?

While many users are concerned about scams on Instagram, or the threat of having their accounts hacked—they also don’t want to delete or deactivate their accounts. Thankfully, there is a compromise. Here are some measures that may help you improve your security and privacy on Instagram:

  • Set a long, unique password.
  • Enable two-factor authentication by clicking Security > Two-Factor Authentication > Get Started.
  • Consider making your account private, so that only approved followers can see it. You can do this in your privacy settings by clicking Settings > Privacy > Account Privacy and toggling Private account.
  • You may also want to visit the Comments or Story option under Settings > Privacy to manage how followers interact with your posts.
  • Check the Add Automatically option under Privacy > Tags to stop tagged photos from being added to your profile.
  • Check the authenticity of the accounts you follow by hitting the three-dot menu on a profile and selecting About this Account. Watch out for red flags like frequent username changes and more.
  • Don’t hesitate to block, mute, restrict, or remove followers that affect your peace of mind or try to breach your account security.
  • Use good antivirus/anti-malware software on whatever device you use to access your Instagram account. In case you accidentally click on something malicious, you’ll have protection for your computer, tablet, or mobile device.

How to deactivate or delete your Facebook account

Malwarebytes - Fri, 06/11/2021 - 15:51

People worldwide use Facebook to connect with friends and family, and to engage in pointless debates with strangers over moderately amusing cat videos. But while some feel that the social media platform is an essential part of life, others find the data scandals and privacy issues disconcerting. For those who wish to take a break from Facebook either temporarily or permanently, instructions for deleting or deactivating your account are below.

  8. Delete your Facebook app for good measure.
The cons of deleting your Facebook account

Deleting your Facebook account can certainly feel liberating. You don’t have to worry about managing your privacy or consuming seemingly endless social media content. But rather than a permanent deletion, some people prefer to take a break from Facebook by deactivating their account for the following reasons:

  • You won’t be able to access Facebook again unless you create a new account.
  • It’s impossible to use Messenger without a Facebook account.
  • Some accounts that you entered through Facebook Login may malfunction. You may need to contact those apps and websites or create new accounts.
  • You’ll permanently lose your data unless you download a copy
  • You’ll lose your app purchases, achievements, and more related to your Facebook login on Oculus.  
Can you undelete Facebook if you change your mind?

Facebook says that it needs up to 90 days from the start of the deletion request to remove everything you’ve posted permanently. It may even keep some data in backup storage for legal issues as part of its data policy. It also offers a 30-day grace period after you erase your account. Here is how to cancel your account deletion within 30 days:

  1. Log in to your Facebook account.
  2. Hit Cancel Deletion.
Deactivating your Facebook account

Deactivating your Facebook is a temporary measure. After you deactivate your account, your Facebook page, including your intro, photos, friends, and posts, is hidden. No one can send you friend requests either. However, your messages are still visible to their recipients. Here are some advantages of deactivating your Facebook instead of deleting it:

  • Your photos, videos, and posts are hidden but not permanently deleted.
  • Facebook Messenger is still fully accessible.
  • You can still access accounts through Facebook Login.
  • You can reactivate Facebook whenever you please by logging in.
How to deactivate your Facebook account from a browser

The same link that allows you to erase your account also allows you to deactivate your account. Hit Deactivate Account and then enter your password to lose access to Facebook temporarily. Alternatively, you can use the following steps:

Cloud vs on premise: 3 reasons the Cloud is winning

Malwarebytes - Fri, 06/11/2021 - 15:26

Thanks to the vast rollout of COVID-19 vaccines to millions of people in the US and Europe, some of us are finally seeing some semblance of a return to normalcy. And organizations, who have experienced first-hand the struggle to stay afloat during months of struggle, are expecting to transition back to how things were.

For some, a life back to normal means employees commuting back to workplaces. Empty cubicles will slowly start filling up again. And face-to-face meetings, either a big group in a conference room or a small one in a coffee shop, will be A Thing once again.

But what about those employees who prefer to work from home, or at least to have the option? And what of businesses happy to be liberated from the constraints of physical workspaces? It seems there are many of both.

The normal we knew of may no longer fit the kind of normal organizations have adjusted for. Remote working during the pandemic has made leadership roles in organizations understand that connectivity—making company data and resources available for all employees who need them, no matter where they are, while keeping that data as secure as possible—is what they and every business really need.

The Cloud, in other words.

Cloud adoption

“Cloud” is a term used to describe a vast network of remote servers located around the world linked together to form a contiguous platform for computer services that can be subdivided and scaled with ease. It has been around for nearly two decades, and organizations adapting a Cloud strategy have been on the uptick, pre-pandemic. And the lockdowns and (some imposed) mandatory work from home (WFH) measures during the pandemic have only accelerated Cloud adoption even further.

It is noted that enterprises are the big spenders on Cloud computing. Yet, many have yet to embrace the Cloud—particularly those in the SMB sector. According to the Small & Medium Business Trend Report from Salesforce, “digital forward SMBs”—or SMBs that have invested in technology, including the cloud, to drive customer interaction and growth—were better equipped to handle the pandemic.

Half and half: While almost half of SMBs in the paper reported digitizing their operations, almost half of them are still behind. (Source: Salesforce)

If you’re still on the fence about whether you should move your data and operations to the Cloud, or you’re locked in the “on-premise versus Cloud” debate on which one is better, we have identified below the three main reasons why organizations, regardless of size, are migrating to the Cloud.

1. Cost efficiency

Setting up servers and making sure that they are physically secure, have uninterrupted power and air conditioning, and are loaded with properly licensed, patched and updated software is no small task. There are high, upfront fees, a multitude of things can go wrong, and it is hard to scale. And the lifetime costs aren’t small either: From electricity bills and maintenance, to that dreaded “end of life” for both hardware and software. When it comes to this kind of computing infrastructure, economies of scale matter, and almost no business can compete with the scale of Cloud providers like Google, Microsoft and Amazon.

Suffice to say, many organizations are opting not to worry about servers and server rooms at all, and instead choosing to pay for what they use by using Cloud infrastructure like AWS, or Cloud services, like Office 365.

2. Security and compliance

Cloud service providers, especially the big-named ones like Amazon and Microsoft, boast of having excellent and powerful security in place by default. And Cloud service providers have made it a point to make their security as robust as possible, relieving businesses of many of the basics they struggle with, such as backups, single sign-on, encryption, firewall configuration, and consistent security updates—you name it. The Cloud doesn’t mean you can forget about security, but it can make it much easier to do the right thing.

The same robustness can be said about the physical security of their servers. It would be extremely hard for intruders to physically break into servers that house an organization’s precious data. Cloud providers keep data safe from physical destruction by keeping it in multiple places, and keep it safe from theft by investing in layers of physical security, like fences, guards, surveillance cameras, and biometric access systems.

Security in the Cloud also reduces the attack surface for insider threats because employees and contractors cannot go in and out of rooms they’re not supposed to go to.

When it comes to disasters—and by this, we mean natural and local ones—locations of on-premise servers are expected to withstand whatever nature can throw at it, may these be floods, earthquakes, tornadoes, and even your random lava spill. However, many on-premise operators don’t have the redundancies they need, seeing them as not cost efficient. On the other hand, redundancy is built into a Cloud or hybrid configuration.

Lastly, we’d like to mention that many Cloud providers comply with various security, privacy, and data protection regulations. In the US, we have the Payment Card Industry Data Security Standard (PCI DSS), the Health Insurance Portability and Accountability Act (HIPAA), and Federal Information Security Management Act (FISMA) among others. Other countries have their own standards that a Cloud provider complies to as well.

The security advantage of Cloud services was graphically illustrated in March this year, after Microsoft released patches for four zero-days being exploited by a group dubbed Hafnium. The patches were quickly reverse engineered by multiple criminal groups and automated attacks began soon after. The attacks turned unpatched Exchange servers into backdoors that could be used to steal data or launch ransomware inside company networks. IT teams dropped everything to find and patch their vulnerable servers, Microsoft released a flurry of tools to help, and the FBI even took the highly unusual step of remotely cleaning up some of the compromised servers.

What was notable about the incident is that it affected on-premise servers with Exchange, but not not the Cloud version. The “patch gap”, the often months-long gap between a patch being made available and it being used—the gap that criminals were so ruthlessly exploiting—simply didn’t exist in the Cloud.

3. Flexibility

The Cloud allows enormous flexibility, whether you’re adapting quickly to good news or bad. Famously, the Cloud allows services to scale up extremely quickly, avoiding many of the technical problems that can come from growing too fast or becoming suddenly popular.

It can also help when businesses are faced with a sudden, unexpected and challenging situation, as many were in April 2020 as COVID spread around the world. Dyer Brown, a Boston-based architectural firm, is an SMB that adopted the Cloud prior to 2020 and was able to successfully and fully shift their entire workforce to remote work. Employees were able to access important files wherever they were, thus, productivity and collaboration weren’t sacrificed. This flexibility afforded by the Cloud not only made it possible for their 50 employees to work offsite but also take care of sick family members, home school kids, and focus on their health more.

It has also been made apparent that flexibility with work schedule due to working remotely has become a make-or-break factor for employees on whether they should stick with their current company or move to a new one. Some even welcome pay cuts in exchange for working from home.

This is something organizational leaders will need to consider seriously.

How a Resident Evil image leaked in a ransomware attack ended up in the middle of $12m copyright claim

Malwarebytes - Thu, 06/10/2021 - 17:43

Back in November, gaming giant Capcom suffered a ransomware attack. In its press notification, it mentioned the various types of data potentially grabbed by their attackers. Things took an ominous turn when they refused to pay the ransom, and the group behind the attack said that was the wrong move. Capcom had the chance to “save data from leakage”; they did not take it. Sure enough, a whole collection of files were leaked soon after.

The threat of data drops from scorned ransomware groups is now a common extortion tactic. What we couldn’t have predicted here, is one of the ramifications of said drop. Time to wind things forward to June 2021 and a date with a lawsuit. The twist? The lawsuit isn’t aimed at the ransomware authors, but the compromised company.

Of data drops and research collections

I used to work in and around game / movie development a long time ago. We were incredibly low budget, and did very low budget things. An invaluable source of help at the time were resource guides and collections. Essentially: Big books filled with work compiled by visual artists, composers, designers, whoever. If you were lucky, the book came with a CD loaded with material from the book. Even luckier? You could use the contents for your own work for free. If the project was commercial, you’d typically pay a license fee of some kind.

There were also companies which curated content from multiple artists, and made sure all the licensing behind the scenes was watertight. Where this often went wrong was if the disc went walkabout away from the book.

Organisations would end up with discs lying around in desks, with nobody sure of the source / who had paid for licensing. If someone ripped disc contents, you’d then end up with self-burnt CDs lying around the place which appeared to be in-house creations. You have to be incredibly careful where resource materials are concerned.

If you’re wondering how this ties into the ransomware attack, I’m about to fill in the blanks.

The unintended consequence of a data leak

An artist in this case is seeking $12m in damages from Capcom, claiming Capcom used their imagery from a resource book / CD in a number of its video game titles. This has all come about off the back of the data leak from the ransomware hack. At least one of the images from the stolen and leaked files shares the same file name as what appears to be an identical image from the book’s CD-ROM.

The Juracek Vs Capcom document can be seen here, along with multiple examples of images potentially making their way into games. Sadly, it doesn’t go into detail on the most fascinating part…whether or not the artist became aware as a result of the data breach and subsequent leak. Most reports simply say the artist is using the breach as part of their evidence. There’s also the question of how they became aware of the images in the dump in the first place.

If I had to guess, incredibly knowledgeable fans saw the high resolution images, wondered where they came from, and perhaps got in touch with the creator. This isn’t an unusual thing to happen. Back in the mid 90s I tracked down the music composer for a AAA game series on Japanese language message boards, in order to tell them how cool their music is. It’s a lot easier to do things like this these days which may be a blessing or a curse, or perhaps a bit of both.

However you stack it up, it promises to be a fascinating day in court. This story raises some other issues, too.

Turning a negative into a positive

Some ransomware groups have tried to mix it up a bit in the realm of PR. They present themselves as Robin Hood style renegades, robbing the rich to give to the poor…or, more specifically, giving to charities. An interesting tactic, except charities face all sorts of problems if they’re gifted ill-gotten gains. As mentioned elsewhere, there’s every possibility the “we’re being helpful, honest” approach is merely a ruse to keep up the pretence of respectability. Here, though, we run into a bit of a problem.

The artist in question has made what they feel to be a valid complaint, and are having their day in court as a result. Being able to tie specific file names from their CD-ROM to named files in Capcom folders off the back of the hack? That probably strengthens their case quite a bit.

Put simply, these ransomware authors…and anyone else, for that matter…can now point to this story as evidence that they did in fact “help” someone in indirect fashion.

New frontiers in the ransomware world

The fallout from the attack could prompt a new ransomware tactic. It’s not a stretch to think breachers will go looking for copyright / related violations. After all, some ransomware groups have already shown an interest in how they can weaponize the data they’ve stolen, beyond simply leaking it.

With so many ways to tie found materials to the original source online, they may view this as an easy PR win. On top of all the other issues with ransomware, we probably don’t need its authors yelling “Look! We’re helping!” every time a new leak hits. When a creator is potentially $12 million out of pocket, it becomes increasingly tricky to argue against it.

Sure, this is still potentially another way for people who don’t actually care about helping people to act as if they do. But if the end result is the same and someone does benefit, it doesn’t really matter a whole lot. As far as the ransomware authors are concerned, they’ll have a collection of individuals telling everyone how cool they are.

It’s to be hoped we don’t end up fighting a PR war on top of the technical battle already raging across networks everywhere. I’m not sure I agree that “any publicity is good publicity”, but good publicity certainly is. So in case anyone is tempted to offer ransomware operators the benefit of the doubt, let’s not forget they’re same organised crime gangs that think little of attacking hospitals.

Russia accused of hacking Dutch police during MH17 investigation

Malwarebytes - Thu, 06/10/2021 - 14:19

Journalists at the Dutch newspaper “De Volkskrant” have reported that the country’s intelligence service, AIVD, discovered in 2017 that Russian hackers had broken into Dutch police systems. The De Volkskrant report is based on knowledge from anonymous sources. The reason behind this act of espionage is thought to be the ongoing MH17 investigation.

MH17

A little background: on July 17, 2014, Malaysia Airlines Flight 17 (MH17) was shot from the sky on its way from Amsterdam to Kuala Lumpur above the Ukraine. The plane was hit by a surface-to-air missile, and as a result, all 298 people on board were killed, the majority of them Dutch.

At that time, there was a revolt of pro-Russian militants against the Ukrainian government which is thought to have been backed by Russia. Russian denied any direct involvement at the time but later admitted to having military intelligence officers in the country. Both the Ukrainian military and the separatists denied responsibility for the MH17 incident.

A large disinformation campaign was launched to obscure who was responsible.

The discovery

The Dutch police only became aware it had been breached after a tip off from AIVD, and the discovery caused a major panic, according to the newspaper. Whether and which data was stolen, is not clear, insiders told the Volkskrant. Understandably, the police network is a huge one and spread out across the country. Apparently the point of first entry was a server of the Police Academy. After discovery, the decision was made that putting a stop to the intrusion as quickly as possible was more important than figuring out what the intruders were after.

So, at this point it is unsure what the exact information was the intruders were after and even whether they were successful in finding that information. According to the Volkskrant, due to a lack of monitoring and logging, the AIVD and Dutch Police have very little knowledge of what the hackers did inside the police network. “There were a lot of question marks,” the newspaper’s source said. “How long had they been inside? Was this the first time? Had they already siphoned off data? That wasn’t clear.”

Dutch police

The Dutch police took the lead in the investigation of the MH17 incident. The Joint Investigation Team (JIT), a special team set up to investigate the MH17 incident, comprises officials from the Dutch Public Prosecution Service and the Dutch police, along with police and criminal justice authorities from Australia, Belgium, Malaysia and Ukraine. On July 5, 2017 the JIT countries decided that the prosecution of those responsible for downing flight MH17 would be conducted in the Netherlands.

The timing of the attack against the police could be coincidental, but it is notable that the attack took place in that same month.

Information feeds disinformation

One possible motive for the attack is disinformation. The best lies are based on truth after all. Reportedly, the Dutch justice department and the Dutch police were targeted with phishing emails and cars filled with listening equipment were found in the vicinity of the “Landelijk Parket”, which is the part of the justice department that deals with both national and international organized crimes. Knowing which facts were already known could be instrumental in building believable lies without revealing new facts.

Disinformation

We have reported before about the Russian disinformation campaigns regarding this incident. More recently, in November of 2020, Bellingcat, which has been instrumental in retrieving information about the attack on flight MH17, published evidence that Bonanza Media, a self-styled independent investigative platform, is in fact a special disinformation project working in coordination with Russia’s military intelligence. The open-source intelligence outfit asserts that:

While we have not yet established conclusively whether the Russia’s military intelligence agency, best known as the GRU, was behind the initial launch and funding of the Bonanza Media project, we have established that shortly after it was launched, senior members of the GRU entered into direct and regular communication with the project leader

It is no coincidence that one of the main forces behind Bonanza is Dutch as well. Together with former Russia Today journalist Yana Yerlashova, Bonanza was set up by blogger and journalist Max van der Werff.

Eliot Higgins, the founder and executive director of Bellingcat has called out what he says are Russian lies, and the interplay between the official Russian position and the disinformation propagated by so-called MH17 “Truthers”, in his recent tweets about the on-going MH17 court hearings.

This video is now being shown in court, showing the Buk traveling south out of Snizhne towards the eventual launch site. The MH17 truthers have repeatedly tried to claim this is fake footage, and Russia has even claimed this was uploaded the day before MH17 was shot down. pic.twitter.com/XdwD5LDXQH

— Eliot Higgins (@EliotHiggins) June 10, 2021 Cozy Bear

Top suspect of the attack on the Dutch police is APT29 (Cozy Bear), a well-known hacking group that the White House linked earlier this year to the Russian Foreign Intelligence Service, also known as the SVR. They are also suspected to be behind the SolarWinds attack and other international espionage cases.

Aftermath

Both the Dutch police and the AIVD did not provide comments on the publication by the Volkskrant, but we do know that the AIVD is closely monitoring a reorganization to improve the security of the Dutch police’s networks.

The international court in The Hague is in the middle of the MH17 trials and Russia’s interference is unlikely to do their case any good, but of course they will deny every involvement.

How to clear cookies

Malwarebytes - Wed, 06/09/2021 - 16:27

Until the information age, cookies were only known as a tasty but unhealthy snack that some people enjoyed, and others avoided. HTTP cookies, also known as computer, browser, or Internet cookies, are similarly divisive. Although some people like the more personalized browsing experience created by cookies, others have privacy concerns.

Cookies are small pieces of information that websites can store in your browser. A website can check that information each time you interact with it, and that allows it to tell you apart from everyone else. Without cookies you would never be able to log in to a website or store items in a shopping cart.

Microsoft fixes seven zero-days, including two PuzzleMaker targets, Google fixes serious Android flaw

Malwarebytes - Wed, 06/09/2021 - 14:50

This patch Tuesday harvest was another big one. The Windows updates alone included seven zero-day vulnerability updates, two of them are actively being used in the wild by a group called PuzzleMaker, four others that have also been seen in the wild, plus one other zero-day vulnerability not known to have been actively exploited. Add to that 45 vulnerabilities that were labelled important, and security updates for Android, Adobe, SAP, and Cisco. You can practically see the IT staff scrambling to figure out what to do first and what needs to be checked before applying the patches.

PuzzleMaker

Security researchers have discovered a new threat actor dubbed PuzzleMaker, that was found using a chain of Google Chrome and Windows 10 zero-day exploits in highly targeted attacks against multiple companies worldwide. Unfortunately the researchers were unable to conclusively identify the Chrome vulnerability that was used (but they do have a suspect). The good news is that the two Windows vulnerabilities in the attack chain were included in the Windows 10 KB5003637 & KB5003635 cumulative updates. These vulnerabilities are listed as CVE-2021-31955, a Windows kernel information disclosure vulnerability, and CVE-2021-31956, a Windows NTFS elevation of privilege vulnerability.

Other critical issues

The other critical patches made available by Microsoft this June include these actively exploited vulnerabilities:

  • CVE-2021-33739, a Microsoft DWM Core Library Elevation of Privilege Vulnerability.
  • CVE-2021-33742 Windows MSHTML Platform Remote Code Execution Vulnerability.
  • CVE-2021-31199 Microsoft Enhanced Cryptographic Provider Elevation of Privilege Vulnerability.
  • CVE-2021-31201 another Microsoft Enhanced Cryptographic Provider Elevation of Privilege Vulnerability.

Not (yet) actively exploited zero day vulnerability:

  • CVE-2021-31968 Windows Remote Desktop Services Denial of Service Vulnerability.

Other critical updates:

  • CVE-2021-31963 Microsoft SharePoint Server Remote Code Execution Vulnerability.
  • CVE-2021-31959 Scripting Engine Memory Corruption Vulnerability.
  • CVE-2021-31967 VP9 Video Extensions Remote Code Execution Vulnerability.
  • CVE-2021-31985 Microsoft Defender Remote Code Execution Vulnerability.
  • CVE-2021-33742 Windows MSHTML Platform Remote Code Execution Vulnerability.
Android

The Android Security Bulletin of June 7 mentions a critical security vulnerability in the System component that “could enable a remote attacker using a specially crafted transmission to execute arbitrary code within the context of a privileged process”, which is as bad as it sounds. That vulnerability, listed as CVE-2021-0507, could allow an attacker to take control of a targeted Android device unless it’s patched.

Cisco

Cisco has issued a patch for a vulnerability in the software-based SSL/TLS message handler of Cisco Firepower Threat Defense (FTD) Software, that could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message through an affected device. SSL/TLS messages sent to an affected device do not trigger this vulnerability. Cisco informs us that there is no workaround for this issue. Patching is the only solution.

SAP

In the SAP advisory for Security Patch Day – June 2021 we can find two issues that are labelled as “Hot News”:

  • CVE-2021-27602 SAP Commerce, versions – 1808, 1811, 1905, 2005, 2011, Backoffice application allows certain authorized users to create source rules which are translated to drools rule when published to certain modules within the application. An attacker with this authorization can inject malicious code in the source rules and perform remote code execution enabling them to compromise the confidentiality, integrity and availability of the application.
  • CVE-2021-27610 Improper Authentication in SAP NetWeaver ABAP Server and ABAP Platform.
Adobe

To top things off, Adobe has released a giant Patch Tuesday security update release that fixes vulnerabilities in ten applications, including Adobe Acrobat (of course), Reader, and Photoshop. Notably five vulnerabilities in Adobe Acrobat and Reader were fixed that address multiple critical vulnerabilities. Acrobat’s determination to cement its place as the new Flash shows no sign of dimming.

Successful exploitation could lead to arbitrary code execution in the context of the current user on both Windows and macOS. The same is true for two critical vulnerabilities in Photoshop that could lead to arbitrary code execution in the context of the current user.

CVE

Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). Which is why we try and link you to the Mitre list of CVE’s where possible. It allows interested parties to find and compare vulnerabilities.

Happy patching, everyone!

TrickBot indictment reveals the scale and complexity of organized cybercrime

Malwarebytes - Tue, 06/08/2021 - 18:07

Back in 2016, we saw the emergence of a botnet mainstay called TrickBot. Initially observed by our Labs team spreading via malvertising campaigns, it quickly became a major problem for businesses everywhere. Whether spread by malvertising or email spam, the end result was the same. Data exfiltration and the threat of constant reinfection were the order of the day.

Over time, it evolved. Tampering with web sessions depending on mobile carrier is pretty smart. Other features such as disabling real-time monitoring from Windows Defender were also added. In fact, wherever you look, there’s the possibility of stumbling upon a TrickBot reference when digging into other attacks.

The tricky problem of “sophisticated” attacks

The word “sophisticated” is used a lot in security research. Sometimes, it’s used even if an attack being discussed is a basic phish, or maybe some very generic malware.

However, TrickBot is a pretty formidable opponent. As is often the case, the “sophisticated” part isn’t necessarily just about the files themselves. There’s also the organisation behind the scenes to contend with. We’re talking people, infrastructure, small groups of individuals all working to make some code, and keep it ticking over. To grab the exfiltrated data and make something of it. Wherever you look where TrickBot is concerned, there’s probably another cluster of specialised people up to no good. This isn’t a good thing when tackling malware developments.

“How bad is it, really?”

Have you ever stopped to consider “what, exactly, are we up against” when dealing with malware? This week’s events are a very good, and rather alarming, illustration.

What happened this week, you ask? That would be a potentially major blow to the TrickBot crew. A Latvian woman has been charged for their alleged role in a transnational cybercrime organisation. That organisation, as you’ll have guessed, is all about TrickBot shenanigans. What’s particularly interesting here, is how it illuminates just how much work goes into development. It isn’t one person sitting in their bedroom. It’s an actual criminal enterprise, run as a business, with lots of different divisions and moving parts.

There are malware managers in hiring roles, hiring developers to produce the files. This is done on Russian language job websites, and made to look as if it’s for “regular” coding jobs. 

There’s folks looking after finances, and testing malware against CAV services. Money mules and spear phishing are thrown into the mix alongside social engineering and international theft of money, personal, and confidential information.

Peeling back the TrickBot onion

This is just skimming the surface of what was happening under the hood. An entire infrastructure was created, with servers, VPNs, and VPS providers combined by the TrickBot crew to create the perfect malware deployment environment. That’s before you get to the crypters, hired to help evade detection from security software. Or how about those responsible for the spamming tools? The folks monitoring bank website flows to figure out how to defeat multi-factor encryption? There’s even someone creating coding tests, to ensure potential malware author hires know what they’re doing in terms of injections.

Make no mistake, the groups infecting millions of computers worldwide and making huge amounts of money aren’t doing it by accident. What cases like United States of America v. Alla Witte show us is that it’s efficient, structured, and very organised indeed.

The basic plan? Infect computers with TrickBot, spread across networks, grab banking details, and then steal funds. Said funds would then be laundered across a variety of bank accounts “controlled by the defendant and others”. Ransomware would also be deployed, for that final splash of cash.

As touched on above, the group hired experts in a variety of cybercrime fields. This was a perfect accompaniment to the modular, ever-evolving TrickBot. This itself was built upon the framework of the older Dyre malware, with all the years of experience and field expertise you’d expect coming along for the ride.

Evading the long arm of the law

Certain elements of the team helped evade detection by making use of multiple tricks to keep out of law enforcement’s reach. Stolen credit cards and fake identities paid for behind the scenes tech like servers and domains. Multiple proxies were used for communications purposes. Emails and attachments were encrypted, and chat in a private messaging server was also locked down. Multiple VPN services made use of around the world are the final anonymous splashes of icing on a very large cake.

Big scams, big numbers

The full arrest warrant document [PDF] is roughly 60 pages long, and contains an incredible amount of information. It breaks everything down by category, explaining how the malware and its injections worked. How the multi-stage laundering took place, including dates / transaction amounts. The wire transfers listed range from $44,900 to $230,400 across most of 2017 to 2018. There’s even an incredible attempted approximate wire transfer of $691,570,000 between the 19 and 20 October, 2017.

It’s possible time has now been called on this TrickBot crew. No matter what happens, you can be sure other groups are out there right now doing much the same things. A few of them will be just as big, just as well organised, and firing even bigger plundered sums of cash around banking infrastructure.

Next time you read about a piece of malware in the news, consider the sobering thought that it is the tip of a very long spear. An in-depth process lies under the surface keeping said malware in operation. How bad is it really? What, exactly, are we up against?

The answer is: all of the above, and more.

800 arrests after police dupe crime groups into using backdoored phones

Malwarebytes - Tue, 06/08/2021 - 12:52

An international operation that monitored an encrypted device company under control of the Federal Bureau of Investigation (FBI) and the Australian Federal Police (AFP) has led to a massive, coordinated string by law enforcement in several countries.

The setup

Law enforcement agencies around the world have long campaigned for encryption backdoors, so they can see what criminals are saying to each other. Unable to break the encryption of existing messaging apps, the FBI and the AFP came up with an ingenious plan to get criminals to use a device for encrypted communication that they could eavesdrop on.

The FBI created an app called AN0M, to fill the void left behind by dismantling several encrypted platforms used by criminals. Custom cellphones with the FBI-controlled platform installed were sold on underground markets and grew in popularity. Of course, not all the users interested in these devices were necessarily criminals, but the phones turned out to be very popular among criminals of all kinds, including outlawed motor gangs, Italian organized crime, Asian crime syndicates, and international drug traffickers.

As a result, law enforcement officials have been monitoring what they had to say for nearly three years.

The operation

The name of the operation was different depending on who you ask. The AFP refers to it as Special Operation Ironside, Europol ran an Operational Task Force to support the sting and called it Greenlight, and the FBI (and many others) call it Operation Trojan Shield. Which is very fitting as it pretended to offer the criminals a shield to hide their messages, but that shield was in fact a Trojan horse.

The goal of the new platform was to target global organized crime, drug trafficking, and money laundering organizations, regardless of where they operated, with an encrypted device that had features that would appeal to organized crime networks, such as remote wipe and duress passwords, to persuade criminal networks to pivot to the device.

The service is said to have provided over 12,000 encrypted devices to over 300 criminal syndicates operating in more than 100 countries.

The cooperation

The FBI had the lead in the investigation aided by the AFP which provided the systems needed to decrypt the messages. Europol supported the  operation by coordinating the international law enforcement community that was involved, by enriching the information picture and bringing the criminal intelligence into ongoing operations to target organized crime and drug trafficking organizations. The following countries participated in the international coalition: Australia, Austria, Canada, Denmark, Estonia, Finland, Germany, Hungary, Lithuania, New Zealand, the Netherlands, Norway, Sweden, the United Kingdom, and the United States.

Is it legal?

Of course it was you would say, since it was run by law enforcement. But listening in on the conversations of people that you have no evidence against is not allowed in many countries. The AFP’s prominent role may be related to Australia’s Telecommunications and other Legislation Amendment (TOLA), passed in 2018. The TOLA provides Australian law enforcement with the ability to make technical assistance requests (TARs) that oblige companies providing technical services in Australia to help them decrypt messages with technical assistance or new capabilities.

Providing a service after taking down the real enablers

It is ironic in a way that the need for a encrypted device company has arisen after the EncroChat system had been compromised so that law enforcement could eavesdrop, and the Sky ECC communication service was unlocked. After these events ANOM was welcomed in criminal circles and passed on by word-of-mouth advertising. Australian Federal Police Commissioner Reece Kershaw:

“Essentially, they have handcuffed each other by endorsing and trusting AN0M and openly communicating on it — not knowing we were watching the entire time.”

You had to know a criminal to get hold of one of these customized phones and you could only communicate with someone on the same platform. This probably helped to limit the number of customers to the “target audience” of the agencies that ran the sting operation.

The results

To say that the operation was a success would be an understatement. Law enforcement agencies report that around 800 suspects have been arrested. Searches of more than 700 houses have resulted in the seizure of over eight tons of cocaine, 22 tons of cannabis and cannabis resin, two tons of synthetic drugs, six tons of synthetic drugs precursors, 250 firearms, 55 luxury vehicles and over $48 million in cash and cryptocurrencies.

Why stop now?

Given the operation was so successful, questions have been raised about why its use wasn’t continued. The decision to stop the operation was reportedly made jointly by all the international partners. But commissioner Kershaw is reported to have hinted of “a legal time frame on this operation” about which more details might be revealed later on. We’ll keep you posted.
