Microsoft Corp. today released software updates to plug at least 570 security holes in its Windows operating systems and other software, almost triple the number of vulnerabilities the software giant fixed in its record-smashing Patch Tuesday release last month. Microsoft attributed the burgeoning patch counts to vulnerability discoveries aided by artificial intelligence.

Nearly 60 of the bugs quashed in July’s Patch Tuesday earned a “critical” severity rating, meaning miscreants or malware could use them to seize remote control over a Windows device with little or no help from the user. Microsoft also addressed three zero-day flaws, including two that are already being exploited in the wild.

Two of the zero-day weaknesses allow an attacker to elevate their user rights on a Windows system, as do approximately 250 other elevation of privilege flaws fixed this month; they include CVE-2026-56155 — an Active Directory Federation Services bug — and CVE-2026-56164, a Microsoft Sharepoint vulnerability.

CVE-2026-50661 is a security feature bypass in Windows BitLocker that could allow attackers to gain access to encrypted data if they have physical access to the device. Microsoft said this bug has been detailed publicly, but that it is not aware of any active exploitation.

In a blog post on July 9, Microsoft Executive Vice President Pavan Davuluri wrote that Windows users will notice “a higher volume of security updates included in each security release” as a result of AI aiding in the discovery of vulnerabilities.

“The pace of vulnerability discovery is changing with advances in AI making it possible to find more issues, faster, across more code, with new mechanisms that can accelerate both discovery and analysis,” Davuluri wrote.

Jack Bicer, director of vulnerability research at Action1, called attention to CVE-2026-48561, a remote code execution flaw in Microsoft Copilot (with a 9.6 CVSS threat score) that allows an unauthorized attacker to execute code over the network. Microsoft says an attacker could exploit this bug by hosting a malicious website that causes Microsoft Edge for Android to automatically send crafted prompts to Copilot when a user visits the site.

As AI advances the state of vulnerability discovery and remediation, it is also making it easier for attackers to quickly devise working exploits for known software flaws. Microsoft has long labeled security bugs using its “exploitability index,” which is Redmond’s best guess as to how likely it is that attackers will be able to figure out a reliable way to exploit a given vulnerability.

But Satnam Narang, senior staff research engineer at Tenable, argues that Microsoft’s exploitability index needs to do a better job of shifting with the machine speed of discovery. For example, Microsoft originally gave this month’s SharePoint zero-day an exploitability rating of “less likely,” although the flaw was added to CISA’s Known Exploited Vulnerabilities list on July 1.

“Anthropic’s Red Team’s own findings for known vulnerabilities (n-days) revealed how fragile this system has become, with its Mythos Preview model being able to produce proof-of-concept exploits for 13 of 14 vulnerabilities that were rated ‘Exploitation Less Likely’ or ‘Exploitation Unlikely,'” Narang said. “What this means is that our way of looking at Patch Tuesday has changed, because the exploitability index is centered around humans, not AI tools, and as these tools continue to improve, defense needs to improve alongside it.”

Chris Goettl at Ivanti observed that the record patch numbers from Microsoft come as a number of other major software makers are increasing their patch cadence, including Adobe which announced today it is moving to twice-monthly security bulletins published on the 2nd and 4th Tuesday of each month (Adobe also cited AI for accelerating their patch cycles). Cisco, Mozilla and Oracle also are shipping updates more frequently, while Google’s patch batches in June 2026 totaled more than 900 security fixes, Goettl noted.

Backing up your Windows system and/or data is always a good idea before applying operating system updates. Given the volume of patches addressed this month it may be wise for end users to wait a few days before applying these fixes. It’s not uncommon for security patches to introduce system stability issues, and those chances probably increase quite a bit with the gigantic patch count released today.

Automox’s rundown

Introduction

This blog is a focused update on the latest updates to the Ransomware Tool Matrix (RTM) and the Ransomware Vulnerability Matrix (RVM) covering three groups that I have published profiles for to help defenders home in on the threats most relevant to them: TheGentlemen, DragonForce, and WarLock.

Rather than write another broad ecosystem summary, the goal of this post is to introduce these profiles, briefly explain why each group matters right now, and give readers direct links to them so defenders can pivot straight into hunting, detection engineering, and patch prioritisation.

For anyone new to the projects, please read the descriptions on GitHub or feel free to watch my talk explaining the project at BSides London.

Why these three groups?

Each of the three groups added in this update represents a different slice of the current ransomware ecosystem:

TheGentlemen

TheGentlemen is a newer operation that has matured quickly, with a large and varied toolkit that reflects how cross-pollinated the affiliate ecosystem has become. The recent internal chat leak gave researchers a rare look into their tradecraft, and the profiles capture both the tooling and the exploited CVEs that have been observed across multiple intrusions. TheGentlemen’s RTM profile is here and RVM profile is here.

DragonForce

DragonForce has continued to escalate throughout 2025 and into 2026, branching into MSP-focused attacks and standing up its own "cartel" model that other affiliates can plug into. Its exploitation of edge devices (Ivanti, Fortinet, SonicWall) and SimpleHelp RMM make it a high-priority threat for any organisation using such systems. DragonForce’s RTM profile is here and RVM profile is here.

WarLock

WarLock jumped onto everyone's radar after the ToolShell SharePoint zero-day exploitation campaign, and has since been linked to a string of edge-application exploits including SmarterMail, SolarWinds Web Help Desk, and Gladinet CentreStack. It is a strong example of a likely China-based operator that lives on zero-day exploitation of internet-facing software. WarLock’s RTM profile is here and RVM profile is here.

Observations and Trends

A few themes are worth flagging across all three profiles:

• BYOVD is now standard, not novel. All three groups have been observed bringing vulnerable drivers to disable or blind EDR. TheGentlemen with ThrottleStop driver, DragonForce with the TrueSight and Hangzhou Shunwang drivers, and WarLock with Antiy, NsecSoft, Rising, and VMTools drivers. If your detection stack is not yet hunting on or blocking suspicious driver loads and known-bad driver hashes, that is a high-priority gap to close.
• Network edge devices and other internet-facing systems remain the front door to victim networks for these groups. Fortinet, Ivanti, SonicWall, SimpleHelp, Microsoft SharePoint, SmarterMail, SolarWinds Web Help Desk, and Gladinet CentreStack all appear across these three profiles. Patch prioritisation that focuses on internet-exposed appliances and admin tooling continues to give defenders a valuable return on effort.
• Legitimate tooling continues to blur the line. Velociraptor, Cloudflared, VSCode Tunnels, AnyDesk, MeshCentral, FreeRDP, PuTTY, OpenSSH, and a long list of legitimate cloud services are all being repurposed for ransomware operations. Defender should use these lists to begin baselining what should exist in their environment and start alerting on the rest.

Conclusion

My recommendation for defenders remains the same as in previous updates: take the tools and CVEs from the RTM and RVM profiles and start threat hunting for their presence, writing detection rules to alert on certain behaviours, and blocking what is not expected or permitted in your environment. These three new profiles should make that easier to scope by group when you need to brief leadership, prioritise a hunt, or map your exposure to a specific campaign.

Here's a few sites that can help with turning the threat intel in these new profiles into detections:

As always, feedback and pull requests are very welcome on both repos. Thanks to everyone who has contributed reports, corrections, and ideas. These projects only stay useful because the community keeps feeding them one way or another.

Artificial intelligence platforms may be just as susceptible to social engineering as human beings, but they are proving remarkably good at finding security vulnerabilities in human-made computer code. That reality is on full display this month with some of the more widely-used software makers — including Apple, Google, Microsoft, Mozilla and Oracle — fixing near record volumes of security bugs, and/or quickening the tempo of their patch releases.

As it does on the second Tuesday of every month, Microsoft today released software updates to address at least 118 security vulnerabilities in its various Windows operating systems and other products. Remarkably, this is the first Patch Tuesday in nearly two years that Microsoft is not shipping any fixes to deal with emergency zero-day flaws that are already being exploited. Nor have any of the flaws fixed today been previously disclosed (potentially giving attackers a heads up in how to exploit the weakness).

Sixteen of the vulnerabilities earned Microsoft’s most-dire “critical” label, meaning malware or miscreants could abuse these bugs to seize remote control over a vulnerable Windows device with little or no help from the user. Rapid7 has done much of the heavy lifting in identifying some of the more concerning critical weaknesses this month, including:

• CVE-2026-41089: A critical stack-based buffer overflow in Windows Netlogon that offers an attacker SYSTEM privileges on the domain controller. No privileges or user interaction are required, and attack complexity is low. Patches are available for all versions of Windows Server from 2012 onwards.
• CVE-2026-41096: A critical RCE in the Windows DNS client implementation worthy of attention despite Microsoft assessing exploitation as less likely.
• CVE-2026-41103: A critical elevation of privilege vulnerability that allows an unauthorized attacker to impersonate an existing user by presenting forged credentials, thus bypassing Entra ID. Microsoft expects that exploitation is more likely.

May’s Patch Tuesday is a welcome respite from April, which saw Microsoft fix a near-record 167 security flaws. Microsoft was among a few dozen tech giants given access to a “Project Glasswing,” a much-hyped AI capability developed by Anthropic that appears quite effective at unearthing security vulnerabilities in code.

Apple, another early participant in Project Glasswing, typically fixes an average of 20 vulnerabilities each time it ships a security update for iOS devices, said Chris Goettl, vice president of product management at Ivanti. On May 11, Apple shipped updates to address at least 52 vulnerabilities and backported the changes all the way to iPhone 6s and iOS 15.

Last month, Mozilla released Firefox 150, which resolved a whopping 271 vulnerabilities that were reportedly discovered during the Glasswing evaluation.

“Since Firefox 150.0.0 released, they have been on a more aggressive weekly cadence for security updates including the release of Firefox 150.0.3 on May Patch Tuesday resolving between three to five CVEs in each release,” Goettl said.

The software giant Oracle likewise recently increased its patch pace in response to their work with Glasswing. In its most recent quarterly patch update, Oracle addressed at least 450 flaws, including more than 300 fixes for remotely exploitable, unauthenticated flaws. But at the end of April, Oracle announced it was switching to a monthly update cycle for critical security issues.

On May 8, Google started rolling out updates to its Chrome browser that fixed an astonishing 127 security flaws (up from just 30 the previous month). Chrome automagically downloads available security updates, but installing them requires fully restarting the browser.

If you encounter any weirdness applying the updates from Microsoft or any other vendor mentioned here, feel free to sound off in the comments below. Meantime, if you haven’t backed up your data and/or drive lately, doing that before updating is generally sound advice.

In 2026, AI agents are being widely used. OpenClaw has become a high-frequency efficiency improvement tool for enterprises and developers with its autonomous decision-making and local execution capabilities. However, several authoritative security agencies have recently issued warnings: OpenClaw is facing multi-dimensional security threats from supply chain poisoning to remote control.

Microsoft today released updates to fix more than 50 security holes in its Windows operating systems and other software, including patches for a whopping six “zero-day” vulnerabilities that attackers are already exploiting in the wild.

Zero-day #1 this month is CVE-2026-21510, a security feature bypass vulnerability in Windows Shell wherein a single click on a malicious link can quietly bypass Windows protections and run attacker-controlled content without warning or consent dialogs. CVE-2026-21510 affects all currently supported versions of Windows.

The zero-day flaw CVE-2026-21513 is a security bypass bug targeting MSHTML, the proprietary engine of the default Web browser in Windows. CVE-2026-21514 is a related security feature bypass in Microsoft Word.

The zero-day CVE-2026-21533 allows local attackers to elevate their user privileges to “SYSTEM” level access in Windows Remote Desktop Services. CVE-2026-21519 is a zero-day elevation of privilege flaw in the Desktop Window Manager (DWM), a key component of Windows that organizes windows on a user’s screen. Microsoft fixed a different zero-day in DWM just last month.

The sixth zero-day is CVE-2026-21525, a potentially disruptive denial-of-service vulnerability in the Windows Remote Access Connection Manager, the service responsible for maintaining VPN connections to corporate networks.

Chris Goettl at Ivanti reminds us Microsoft has issued several out-of-band security updates since January’s Patch Tuesday. On January 17, Microsoft pushed a fix that resolved a credential prompt failure when attempting remote desktop or remote application connections. On January 26, Microsoft patched a zero-day security feature bypass vulnerability (CVE-2026-21509) in Microsoft Office.

Kev Breen at Immersive notes that this month’s Patch Tuesday includes several fixes for remote code execution vulnerabilities affecting GitHub Copilot and multiple integrated development environments (IDEs), including VS Code, Visual Studio, and JetBrains products. The relevant CVEs are CVE-2026-21516, CVE-2026-21523, and CVE-2026-21256.

Breen said the AI vulnerabilities Microsoft patched this month stem from a command injection flaw that can be triggered through prompt injection, or tricking the AI agent into doing something it shouldn’t — like executing malicious code or commands.

“Developers are high-value targets for threat actors, as they often have access to sensitive data such as API keys and secrets that function as keys to critical infrastructure, including privileged AWS or Azure API keys,” Breen said. “When organizations enable developers and automation pipelines to use LLMs and agentic AI, a malicious prompt can have significant impact. This does not mean organizations should stop using AI. It does mean developers should understand the risks, teams should clearly identify which systems and workflows have access to AI agents, and least-privilege principles should be applied to limit the blast radius if developer secrets are compromised.”

The SANS Internet Storm Center has a clickable breakdown of each individual fix this month from Microsoft, indexed by severity and CVSS score. Enterprise Windows admins involved in testing patches before rolling them out should keep an eye on askwoody.com, which often has the skinny on wonky updates. Please don’t neglect to back up your data if it has been a while since you’ve done that, and feel free to sound off in the comments if you experience problems installing any of these fixes.

Microsoft today issued patches to plug at least 113 security holes in its various Windows operating systems and supported software. Eight of the vulnerabilities earned Microsoft’s most-dire “critical” rating, and the company warns that attackers are already exploiting one of the bugs fixed today.

January’s Microsoft zero-day flaw — CVE-2026-20805 — is brought to us by a flaw in the Desktop Window Manager (DWM), a key component of Windows that organizes windows on a user’s screen. Kev Breen, senior director of cyber threat research at Immersive, said despite awarding CVE-2026-20805 a middling CVSS score of 5.5, Microsoft has confirmed its active exploitation in the wild, indicating that threat actors are already leveraging this flaw against organizations.

Breen said vulnerabilities of this kind are commonly used to undermine Address Space Layout Randomization (ASLR), a core operating system security control designed to protect against buffer overflows and other memory-manipulation exploits.

“By revealing where code resides in memory, this vulnerability can be chained with a separate code execution flaw, transforming a complex and unreliable exploit into a practical and repeatable attack,” Breen said. “Microsoft has not disclosed which additional components may be involved in such an exploit chain, significantly limiting defenders’ ability to proactively threat hunt for related activity. As a result, rapid patching currently remains the only effective mitigation.”

Chris Goettl, vice president of product management at Ivanti, observed that CVE-2026-20805 affects all currently supported and extended security update supported versions of the Windows OS. Goettl said it would be a mistake to dismiss the severity of this flaw based on its “Important” rating and relatively low CVSS score.

“A risk-based prioritization methodology warrants treating this vulnerability as a higher severity than the vendor rating or CVSS score assigned,” he said.

Among the critical flaws patched this month are two Microsoft Office remote code execution bugs (CVE-2026-20952 and CVE-2026-20953) that can be triggered just by viewing a booby-trapped message in the Preview Pane.

Our October 2025 Patch Tuesday “End of 10” roundup noted that Microsoft had removed a modem driver from all versions after it was discovered that hackers were abusing a vulnerability in it to hack into systems. Adam Barnett at Rapid7 said Microsoft today removed another couple of modem drivers from Windows for a broadly similar reason: Microsoft is aware of functional exploit code for an elevation of privilege vulnerability in a very similar modem driver, tracked as CVE-2023-31096.

“That’s not a typo; this vulnerability was originally published via MITRE over two years ago, along with a credible public writeup by the original researcher,” Barnett said. “Today’s Windows patches remove agrsm64.sys and agrsm.sys. All three modem drivers were originally developed by the same now-defunct third party, and have been included in Windows for decades. These driver removals will pass unnoticed for most people, but you might find active modems still in a few contexts, including some industrial control systems.”

According to Barnett, two questions remain: How many more legacy modem drivers are still present on a fully-patched Windows asset; and how many more elevation-to-SYSTEM vulnerabilities will emerge from them before Microsoft cuts off attackers who have been enjoying “living off the land[line] by exploiting an entire class of dusty old device drivers?”

“Although Microsoft doesn’t claim evidence of exploitation for CVE-2023-31096, the relevant 2023 write-up and the 2025 removal of the other Agere modem driver have provided two strong signals for anyone looking for Windows exploits in the meantime,” Barnett said. “In case you were wondering, there is no need to have a modem connected; the mere presence of the driver is enough to render an asset vulnerable.”

Immersive, Ivanti and Rapid7 all called attention to CVE-2026-21265, which is a critical Security Feature Bypass vulnerability affecting Windows Secure Boot. This security feature is designed to protect against threats like rootkits and bootkits, and it relies on a set of certificates that are set to expire in June 2026 and October 2026. Once these 2011 certificates expire, Windows devices that do not have the new 2023 certificates can no longer receive Secure Boot security fixes.

Barnett cautioned that when updating the bootloader and BIOS, it is essential to prepare fully ahead of time for the specific OS and BIOS combination you’re working with, since incorrect remediation steps can lead to an unbootable system.

“Fifteen years is a very long time indeed in information security, but the clock is running out on the Microsoft root certificates which have been signing essentially everything in the Secure Boot ecosystem since the days of Stuxnet,” Barnett said. “Microsoft issued replacement certificates back in 2023, alongside CVE-2023-24932 which covered relevant Windows patches as well as subsequent steps to remediate the Secure Boot bypass exploited by the BlackLotus bootkit.”

Goettl noted that Mozilla has released updates for Firefox and Firefox ESR resolving a total of 34 vulnerabilities, two of which are suspected to be exploited (CVE-2026-0891 and CVE-2026-0892). Both are resolved in Firefox 147 (MFSA2026-01) and CVE-2026-0891 is resolved in Firefox ESR 140.7 (MFSA2026-03).

“Expect Google Chrome and Microsoft Edge updates this week in addition to a high severity vulnerability in Chrome WebView that was resolved in the January 6 Chrome update (CVE-2026-0628),” Goettl said.

As ever, the SANS Internet Storm Center has a per-patch breakdown by severity and urgency. Windows admins should keep an eye on askwoody.com for any news about patches that don’t quite play nice with everything. If you experience any issues related installing January’s patches, please drop a line in the comments below.

Microsoft this week pushed security updates to fix more than 60 vulnerabilities in its Windows operating systems and supported software, including at least one zero-day bug that is already being exploited. Microsoft also fixed a glitch that prevented some Windows 10 users from taking advantage of an extra year of security updates, which is nice because the zero-day flaw and other critical weaknesses affect all versions of Windows, including Windows 10.

Affected products this month include the Windows OS, Office, SharePoint, SQL Server, Visual Studio, GitHub Copilot, and Azure Monitor Agent. The zero-day threat concerns a memory corruption bug deep in the Windows innards called CVE-2025-62215. Despite the flaw’s zero-day status, Microsoft has assigned it an “important” rating rather than critical, because exploiting it requires an attacker to already have access to the target’s device.

“These types of vulnerabilities are often exploited as part of a more complex attack chain,” said Johannes Ullrich, dean of research for the SANS Technology Institute. “However, exploiting this specific vulnerability is likely to be relatively straightforward, given the existence of prior similar vulnerabilities.”

Ben McCarthy, lead cybersecurity engineer at Immersive, called attention to CVE-2025-60274, a critical weakness in a core Windows graphic component (GDI+) that is used by a massive number of applications, including Microsoft Office, web servers processing images, and countless third-party applications.

“The patch for this should be an organization’s highest priority,” McCarthy said. “While Microsoft assesses this as ‘Exploitation Less Likely,’ a 9.8-rated flaw in a ubiquitous library like GDI+ is a critical risk.”

Microsoft patched a critical bug in Office — CVE-2025-62199 — that can lead to remote code execution on a Windows system. Alex Vovk, CEO and co-founder of Action1, said this Office flaw is a high priority because it is low complexity, needs no privileges, and can be exploited just by viewing a booby-trapped message in the Preview Pane.

Many of the more concerning bugs addressed by Microsoft this month affect Windows 10, an operating system that Microsoft officially ceased supporting with patches last month. As that deadline rolled around, however, Microsoft began offering Windows 10 users an extra year of free updates, so long as they register their PC to an active Microsoft account.

Judging from the comments on last month’s Patch Tuesday post, that registration worked for a lot of Windows 10 users, but some readers reported the option for an extra year of updates was never offered. Nick Carroll, cyber incident response manager at Nightwing, notes that Microsoft has recently released an out-of-band update to address issues when trying to enroll in the Windows 10 Consumer Extended Security Update program.

“If you plan to participate in the program, make sure you update and install KB5071959 to address the enrollment issues,” Carroll said. “After that is installed, users should be able to install other updates such as today’s KB5068781 which is the latest update to Windows 10.”

Chris Goettl at Ivanti notes that in addition to Microsoft updates today, third-party updates from Adobe and Mozilla have already been released. Also, an update for Google Chrome is expected soon, which means Edge will also be in need of its own update.

The SANS Internet Storm Center has a clickable breakdown of each individual fix from Microsoft, indexed by severity and CVSS score. Enterprise Windows admins involved in testing patches before rolling them out should keep an eye on askwoody.com, which often has the skinny on any updates gone awry.

As always, please don’t neglect to back up your data (if not your entire system) at regular intervals, and feel free to sound off in the comments if you experience problems installing any of these fixes.

[Author’s note: This post was intended to appear on the homepage on Tuesday, Nov. 11. I’m still not sure how it happened, but somehow this story failed to publish that day. My apologies for the oversight.]

The scourge of ransomware continues primarily because of three main reasons: Ransomware-as-a-Service (RaaS), cryptocurrency, and safe havens.

• RaaS platforms enable aspiring cybercriminals to join a gang and begin launching attacks with a support system that help extract ransom payments from their victims.
• Cryptocurrency enables cybercriminals to receive funds from victims around the world without the option to freeze or refund them due to the immutable nature of the virtual funds.
• Safe havens are countries that permit cybercriminals to launch attacks without immediate fear of arrest, enabling them to earn vast fortunes through ransomware campaigns.

With these three challenges in mind, law enforcement and governments have a very difficult job to do when it comes to fighting ransomware but fight it they must. In this blog we shall recall what counter-ransomware activities took place in 2024, analyse their effectiveness, and assess how the landscape shall evolve as a result.

A podcast version of this blog is also available here.

Ransomware Operator Arrests and Sanctions

During 2024, there were significant disruption operations by law enforcement and financial authorities targeting individuals behind ransomware campaigns (see the Table below). The main focus of 2024 for Western law enforcement was squarely on the LockBit RaaS and its affiliates as it was the largest and highest earning ransomware operation to date.

Several key players of the ransomware ecosystem were arrested, including the main developer of LockBit ransomware. Interestingly, Russian law enforcement also decided to arrest ransomware threat actors located in Moscow and Kaliningrad as well.

The ransomware ecosystem has fragmented due to the law enforcement disruptions of the largest players, such as ALPHV/BlackCat and LockBit. In the case of ALPHV/BlackCat, the operators staged a law enforcement takedown as they put up a fake seizure notice as part of an exit scam in March 2024 after the attack on UnitedHealth.

Following these disruptions, some affiliates have migrated to less effective strains or launched their own strains. This includes Akira and RansomHub at the top of the list as well as Hunters International and PLAY.

Cryptocurrency Exchanges Disrupted

During 2024, law enforcement seized funds from and sanctioned a number of cryptocurrency exchanges and individuals running payment processors using cryptocurrency (see the Table below).

One of the most interesting disclosures this year came from the UK National Crime Agency (NCA) around Operation Destablise. The NCA linked payments to ransomware gangs to money laundering networks used by Russian oligarchs to covertly purchase property and Russia Today, the state-run media organization, to covertly fund pro-Russia foreign entities.

Another notable investigation in 2024 was when the US Treasury sanctioned more Russian cryptocurrency exchanges, such as PM2BTC and Cryptex, that led to money launderers that facilitate the cashing out of ransom payments being arrested by Russian law enforcement.

Safe Havens Enabling Ransomware

While ransomware is a global problem, there are only a few countries that are to blame for this rapid expansion of the ransomware ecosystem. The state that is blamed the most for preventing many ransomware operators from facing justice is Russia. There are explicit rules posted to Russian-speaking cybercrime forums that state as long as members avoid targeting Russia and the Commonwealth of Independent States (CIS), they are free to operate.

The Russian ransomware safe haven theory was further proven following sanctions levied against Evil Corp by the UK, US, and Australia. One of the sanctioned men connected to Evil Corp was Eduard Benderskiy, a former Russian federal security service (FSB) official. Benderskiy is reportedly the father-in-law of Maksim Yakubets, the leader of Evil Corp, an organized cybercrime group responsible for multiple ransomware strains including BitPaymer, WastedLocker, Hades, PhoenixLocker, and MacawLocker. In total, Evil Corp has reportedly extorted at least $300 million from victims globally, according to the UK NCA. It is now clear that Evil Corp has protection from a highly connected Russian FSB official who has also been involved in multiple overseas assassinations on behalf of the Kremlin, according to Bellingcat investigators.

While a number of ransomware operators were arrested in 2024 and some were extradited to the US, the work done by law enforcement specializing in cybercrime was put in the spotlight during the August 2024 prisoner swap. Multiple countries decided to release cybercriminals, spies and an assassin as part of a historic prisoner exchange with Russia at an airport in Ankara, Turkey. The US negotiated the release of 16 people from Russia, including five Germans as well as seven Russian citizens who were political prisoners in their own country.

Notably, from a cybercrime intelligence perspective, the Russian nationals released from the West included the infamous cybercriminals Roman Seleznev and Vladislav Klyushin. The latter, Klyushin, was sentenced in 2023 to nine years in US prison after he was caught in a $93 million stock market cheating scheme that involved hacking into US companies for insider knowledge. The other cybercriminal, Seleznev, was sentenced to 27 years in prison in 2017 for stealing and selling millions of credit card numbers from 500 businesses using point-of-sale (POS) malware and causing more than $169 million in damage to small businesses and financial institutions, including those in the US.

In 2024, we saw several more Russian nationals get extradited to the US after being arrested by law enforcement in the country they were residing in. This includes the Phobos operator living in South Korea and the LockBit developer living in Israel. This follows others arrested in previous years such as a TrickBot developer arrested in South Korea as well as the two LockBit affiliates extradited to the US. There is a potential that these Russian nationals involved in ransomware could be used in prisoner exchanges in the future.

Further, another curious trend in 2024 was that some Russians inside Russia, which is firmly considered a safe haven for ransomware gang, did get arrested. This includes the SugarLocker operators arrested in Moscow and the LockBit affiliate Wazawaka who was arrested in Kaliningrad. This is alongside the money launderers arrested around Russia linked to the Cryptex exchange.

The arrests of Russian nationals in Russia for ransomware activities appear to be more symbolic than a true crackdown on this type of activity. This is because there are several dozen Russian-speaking ransomware gangs that continue to operate, as well as a plethora of other types of cybercrime in the Russian-speaking underground.

Outlook

In 2024, there was lots of significant action by law enforcement to shake up the ransomware economy. One of the main successes of the notable Operation Cronos action taken against LockBit was the sowing of distrust and disharmony in the ransomware ecosystem. Despite the admins of LockBit trying to recover, their reputation and army of affiliates have been smashed.

Many of Russian law enforcement activities could all be related to the costs of the Russian invasion of Ukraine. Russian authorities seizing funds of the illicit cryptocurrency exchanges could be to pay for the war in Ukraine and they could be recruiting arresting cybercriminals for offensive cyber operations related to the war in Ukraine. The true motivations of Russian law enforcement arresting these specific ransomware operators but allowing others to operate are unclear. The cybercriminals could also simply have not paid their protection money or lack connections in the FSB like Evil Corp has.

Due to the fall of LockBit and ALPHV/BlackCat in 2024, there has been a rise of other ransomware groups like RansomHub and Akira to fill the vacuum. However, the rate of attacks by these emerging groups is still noticeably lower than when LockBit was operating at full force. This should be perceived as a success for law enforcement operations in 2024 due to the overall number of ransomware attacks lowering, which we should all be thankful for.
