The post Ransomware review: May 2023 appeared first on Malwarebytes Labs.

_This article is based on research by Marcelo Rivero, Malwarebytes' ransomware specialist, who monitors information published by ransomware gangs on their Dark Web sites. In this report, "known attacks" are those where the victim didn't pay a ransom. This provides the best overall picture of ransomware activity, but the true number of attacks is far higher._

In April, LockBit maintained its position as the top ransomware attacker and was also observed expanding into the Mac space. Meanwhile, Cl0p, which dramatically expanded its attack operations in March, has gone quiet this month, despite Microsoft observing them exploiting PaperCut vulnerabilities.

LockBit's macOS ransomware is an interesting development in the threat landscape, showing that the group is dipping its toes into the historically ransomware-free Mac environment. The variant, targeting macOS arm64 architecture, first appeared on VirusTotal in November and December 2022 but went unnoticed until late April when it was discovered by MalwareHunterTeam. 

The LockBit macOS samples analyzed by Malwarebytes seem ineffective due to being unsigned, not accounting for TCC/SIP restrictions, and being riddled with bugs, like buffer overflows, causing premature termination when executed on macOS.

“The LockBit encryptor doesn’t look particularly viable in its current form, but I’m definitely going to be keeping an eye on it,” says Thomas Reed, director of Mac and mobile platforms at Malwarebytes. “The viability may improve in the future. Or it may not, if their tests aren’t promising.”

Keep an eye out, because LockBit's work in developing a macOS ransomware variant—plagued though it may currently be—could signal a trend toward more Mac-targeting ransomware in the future.

Known ransomware attacks by industry sector, April 2023

**Cl0p** ransomware, which gained prominence in March by exploiting a zero-day vulnerability in GoAnywhere MFT, went comparatively silent with just four attacks in April. Nevertheless, the gang was seen last month exploiting vulnerabilities in PaperCut servers to steal corporate data. 

PaperCut is a popular printing management software which was targeted by both Cl0p and LockBit in April using two gnarly vulnerabilities: one allowing remote code execution (CVE-2023-27350) and the other enabling information disclosure (CVE-2023-27351). Once gaining initial access, Cl0p members sneakily deploy the TrueBot malware and a Cobalt Strike beacon to creep through the network, grabbing data along the way. 

Cl0p clearly has a history of exploiting platforms like Accellion FTA and GoAnywhere MFT, and now they've set their sights on PaperCut. So, if you're using PaperCut MF or NG, upgrade pronto and patch these two vulnerabilities!

**Vice Society**, notorious for targeting the education sector, has recently advanced their operations by adopting a sneaky PowerShell script for automated data theft. Discovered by Palo Alto Networks Unit 42, the new data exfiltration tool cleverly employs "living off the land" (LOTL) techniques to avoid detection. For instance, the script employs system-native cmdlets to search and exfiltrate data, minimizing its footprint and maintaining a low profile.

Separately, the **Play** ransomware group has whipped up two fancy .NET tools, Grixba and VSS Copying Tool, to make their cyberattacks more effective.

Grixba checks for antivirus programs, EDR suites, backup tools to help them plan the next steps of the attack. VSS Copying Tool, meanwhile, tiptoes around the Windows Volume Shadow Copy Service (VSS) to steal files from system snapshots and backup copies. Both tools were cooked up with the Costura .NET development tool for easy deployment on their victims' systems.

As Vice Society, Play, and other ransomware groups increasingly adopt advanced LOTL methods and sophisticated tools like Grixba, the capacity to proactively identify both malicious tools and the malicious use of legitimate tools within a network will undoubtedly become the deciding factor in an organization's defense strategy moving forward.

As for other trends, the USA still tops the charts as the most affected country, with the services industry getting the brunt of the attacks, as both have been the case all year. The **education sector** has its highest number of attackers (21) since January. Meanwhile, the **healthcare sector** saw a huge surge in attacks (37) in April, the highest it's been all year.

**New players****Akira**

Akira is a fresh ransomware hitting enterprises globally since March 2023, having already published in April the data of nine companies across different sectors like education, finance, and manufacturing. When executed, the ransomware deletes Windows Shadow Volume Copies, encrypts files with specific extensions, and appends the .akira extension to the encrypted files.

Like most ransomware gangs these days, the Akira gang steals corporate data before encrypting files for the purposes of double-extortion. So far, the leaked info published on their leak site—which looks retro and lets you navigate with typed commands—ranges from 5.9 GB to a whopping 259 GB.

Akira demands ransoms from $200,000 to millions of dollars, and it seems they are willing to lower ransom demands for companies that only want to prevent the leaking of stolen data without needing a decryptor.

**CrossLock**

CrossLock is a new ransomware strain using the Go programming language, which makes it more difficult to reverse engineer and boosts its compatibility across platforms. 

The ransomware employs tactics to avoid analysis, such as looking for the WINE environment (to determine if their ransomware is being executed within an analysis or sandbox environment) and tweaking Event Tracing for Windows (ETW) functions (to disrupt the flow of information that security tools and analysts rely on to identify suspicious behavior).

In April, the CrossLock Ransomware Group said they targeted Valid Certificadora, a Brazilian IT & ITES company.

**Trigona**

Trigona ransomware emerged in October 2022 and has targeted various sectors worldwide, including six in April. Operators use tools like NetScan, Splashtop, and Mimikatz to gain access, perform reconnaissance, and gather sensitive information from target systems. They also employ batch scripts to create new user accounts, disable security features, and cover their tracks. 

**Dunghill Leak**

Dunghill Leak is a new ransomware that evolved from the Dark Angels ransomware, which itself came from Babuk ransomware. In April it published the data of two companies, including Incredible Technologies, an American developer and manufacturer of coin-operated video games. The Dunghill Leak gang claims they have access to 500 GB of the company's data, including game files and tax payment reports. Researchers think Dunghill Leak is just a rebranded Dark Angels.

**Money Message**

Money Message is a new ransomware which targets both Windows and Linux systems. In April, criminals used Money Message to hit at least 10 victims, mostly in the US and from various industries. The gang also targeted some big-time companies worth billions of dollars, such as Taiwanese PC parts maker MSI (Micro-Star International).

Money Message uses advanced encryption techniques and leaves a ransom note called "money\_message.log." 

Our Ransomware Emergency Kit contains the information you need to defend against ransomware-as-a-service (RaaS) gangs.

**How to avoid ransomware**

*   **Block common forms of entry.** Create a plan for patching vulnerabilities in internet-facing systems quickly; and disable or harden remote access like RDP and VPNs.
*   **Prevent intrusions.** Stop threats early before they can even infiltrate or infect your endpoints. Use endpoint security software that can prevent exploits and malware used to deliver ransomware.
*   **Detect intrusions.** Make it harder for intruders to operate inside your organization by segmenting networks and assigning access rights prudently. Use EDR or MDR to detect unusual activity before an attack occurs.
*   **Stop malicious encryption.** Deploy Endpoint Detection and Response software like Malwarebytes EDR that uses multiple different detection techniques to identify ransomware, and ransomware rollback to restore damaged system files.
*   **Create offsite, offline backups.** Keep backups offsite and offline, beyond the reach of attackers. Test them regularly to make sure you can restore essential business functions swiftly.
*   **Don’t get attacked twice.** Once you've isolated the outbreak and stopped the first attack, you must remove every trace of the attackers, their malware, their tools, and their methods of entry, to avoid being attacked again.

We take a look at trouble brewing in browser land after a controversial Windows update leaves Chrome fans without a useful feature.

The post Microsoft vs Google spat sees users rolling back security updates to fix browser issues appeared first on Malwarebytes Labs.

We like to imagine we’re in total control of our desktop experience, carefully curated to look and work the way we want it to. However, every so often a story comes along which reminds us how little control we have when the big players notice one another's existence. A recent Windows update really wants you to use Edge instead of rival browsers, to the extent that some features in those rival browsers are breaking.

A lot of people will only ever use Microsoft's default Edge browser to download another browser they'd rather use. Last year, Chrome made some changes to how you go about making it your default browser, after you've downloaded it with Edge. One "Default" button to press, and boom…your default browser is set to Chrome without having to dig around in your system settings.

This is how things should work, and for a while they did! As Gizmodo notes, this was not to be the case for long.

Microsoft released update KB5025221 last month, and users of Chrome quickly began to flag peculiar experiences. From a Reddit user:

> If Chrome is set as the default browser, clicking on the link shortcut will open the link in chrome, but also open the Windows settings on the default apps. Anyone know where this behaviour comes from? It doesn't happen if we change the default browser to Edge.

Elsewhere, we have a thread about how someone’s 600 business devices all exhibit the same behaviour:

> Opening chrome causes default app settings to open each and every time. After today's cumulative update for Windows 10 and 11, 2023-04, every time I open Chrome the default app settings of windows will open. I've tried many ways to resolve this without luck. This is happening to all 600 systems with the update. Removing the update makes the issue go away. Anyone else having this issue? This does not occur when opening edge or brave browser, only Chrome for us.

A quick glance at the replies illustrates that Todd isn’t the only one impacted, as well as presenting the solution:

> Good morning Todd, We're having the same issue through our organization as well. We're on Windows 10 machines and pushed updates the last couple days. Many machines here seeing the issue. We may have just found a fix. Remove the Security Update KB5025221 and restart, this removes the problem. Looks to have fixed several machines just these last few minutes. May need to block KB5025221 until it's reissued.

Yes, to prevent this behaviour you had to make a decision on removing cumulative security updates. What did KB5025221 offer users? That would be fixes for no fewer than “ten issues that could lead to crashes, compatibility problems, and bugs in the operating system”. Would people really want to gamble by removing such a thing in order to prevent the aggravating system popups when opening Chrome?

It seems not, looking at the various replies to threads on this posted to Reddit and elsewhere. Informing users of the reason for the popups was the more sensible course of action on display. Even so, the mere possibility of people considering removing security updates to fix browser wars (intentional or otherwise) is a terrible position to find yourself in. Even without having to decide what to keep or remove because competing programs on your desktop may be having a fist fight, there are other aspects at play.

Way back in 2004, adware giants Direct Revenue went head to head in a court of law with ad company Avenue Media. The spectacularly named article “Adware cannibals feast on each other” describes how adware vendors thirsty for profit battled for desktop supremacy. The infamous Direct Revenue was accused of detecting the presence of rivals and attempting to uninstall them from PCs. This involved killing a competitor’s program and deleting registry entries to prevent it coming back to life. Indeed, from the Direct Revenue user agreement:

> You further understand and agree, by installing the software, that the software may, without any further prior notice to you, remove, disable or render inoperative other adware programs resident on your computer.

Considering just one Direct Revenue product like Aurora could make a system keel over, the last thing you’d want is half a dozen competing products all playing whack-a-mole with registry entries and who knows what else.

This is, of course, an extreme example from a very extreme time. Aggravating system popups and browser frustrations are not on the same level. Pondering update rollbacks, however, could direct us to such a place by means of another route. It’s to everyone’s benefit if these battles _don’t_ spark the digital touch paper.

For now, Chrome’s default button has been removed as a result of this most recent Windows update. All this, on top of aggravating pop up messages, space hogging adverts, and overly complicated user actions being required just to make a decision. We’ll have to wait and see what happens next in the battle of the browsers. It’s not quite at the “whoever wins, we lose” stage but it’s hard to argue a case where any of this benefits the people using these products.

Microsoft vs Google spat sees users rolling back security updates to fix browser issues

An advanced persistent threat (APT) actor known as Dragon Breath has been observed adding new layers of complexity to its attacks by adopting a novel DLL side-loading mechanism.
"The attack is based on a classic side-loading attack, consisting of a clean application, a malicious loader, and an encrypted payload, with various modifications made to these components over time," Sophos researcher

Advanced Persistent Threat

An advanced persistent threat (APT) actor known as **Dragon Breath** has been observed adding new layers of complexity to its attacks by adopting a novel DLL side-loading mechanism.

"The attack is based on a classic side-loading attack, consisting of a clean application, a malicious loader, and an encrypted payload, with various modifications made to these components over time," Sophos researcher Gabor Szappanos said.

"The latest campaigns add a twist in which a first-stage clean application 'side'-loads a second clean application and auto-executes it. The second clean application side-loads the malicious loader DLL. After that, the malicious loader DLL executes the final payload."

Operation Dragon Breath, also tracked under the names APT-Q-27 and Golden Eye, was first documented by QiAnXin in 2020, detailing a watering hole campaign designed to trick users into downloading a trojanized Windows installer for Telegram.

A subsequent campaign detailed by the Chinese cybersecurity company in May 2022 highlighted the continued use of Telegram installers as a lure to deploy additional payloads such as gh0st RAT.

Dragon Breath is also said to be part of a larger entity called Miuuti Group, with the adversary characterized as a "Chinese-speaking" entity targeting the online gaming and gambling industries, joining the likes of other Chinese activity clusters like Dragon Castling, Dragon Dance, and Earth Berberoka.

The double-dip DLL side-loading strategy, per Sophos, has been leveraged in attacks targeting users in the Philippines, Japan, Taiwan, Singapore, Hong Kong, and China. These attempted intrusions were ultimately unsuccessful.

The initial vector is a fake website hosting an installer for Telegram that, when opened, creates a desktop shortcut that's designed to load malicious components behind the scenes upon launch, while also displaying to the victim the Telegram app user interface.

What's more, the adversary is believed to have created multiple variations of the scheme in which tampered installers for other apps, such as LetsVPN and WhatsApp, are used to initiate the attack chain.

The next stage involves the use of a second clean application as an intermediate to avoid detection and load the final payload via a malicious DLL.

The payload functions as a backdoor capable of downloading and executing files, clearing event logs, extracting and setting clipboard content, running arbitrary commands, and stealing cryptocurrency from the MetaMask wallet extension for Google Chrome.

"DLL sideloading, first identified in Windows products in 2010 but prevalent across multiple platforms, continues to be an effective and appealing tactic for threat actors," Szappanos said.

"This double-clean-app technique employed by the Dragon Breath group, targeting a user sector (online gambling) that has traditionally been less scrutinized by security researchers, represents the continued vitality of this approach."
