EDRKillShifter is getting a dangerous upgrade
The new malware can disable AV and EDR from reputable vendors
Sophos, Bitdefender, and Kaspersky among the tools being targeted
Cybercriminals appear to have improved their antivirus-killing capabilities, as recent research suggest a new tool being shared within the underground community.
In a new report, security researchers from Sophos said multiple ransomware groups are successfully disabling endpoint detection and response (EDR) systems before deploying the encryptor.
Originally, the group known as RansomHub developed a tool called EDRKillShifter, which Sophos says is now made obsolete thanks to this new and improved variant. The new tool can disable security software from multiple high-end vendors such as Sophos, Bitdefender, and Kaspersky.

Shifting strategies
The malware is often packed using a service called HeartCrypt, which obfuscates the code to evade detection.
Sophos found the attackers are using all sorts of obfuscation and anti-analysis techniques to protect their tools from security defenders, and in some cases, they’re even using signed drivers (either stolen or compromised).
In one case, the malicious code was embedded inside a legitimate utility, Beyond Compare’s Clipboard Compare tool, the researchers explained.
Sophos also said that multiple ransomware groups are using this new EDR-killing tool, suggesting a high level of collaboration between players.

EDRKillShifter was first spotted in mid-2024, after a failed attempt to disable an antivirus and deploy ransomware.
Sophos then uncovered that the malware dropped a legitimate, but vulnerable driver.
Now, it seems there is a new method – taking an already legitimate executable and modifying it locally by inserting malicious code and payload resources (as was the case with Beyond Compare’s tool). This is often done after the attacker has access to a

Gamers seeking performance enhancements or special abilities through third-party patches and mods may be unwittingly exposing themselves to sophisticated malware, experts have warned.
Recent findings from Dr.Web revealed a malware family known as “Trojan.Scavenger” which targets Windows users by disguising itself as cheats or enhancements for popular games.
This seemingly harmless mod can ultimately compromise crypto wallets, password managers, and web browsers, posing serious risks to user privacy and digital assets.

When cheats become covert threats
The infection chain begins when users download ZIP archives claiming to improve performance in games including the likes of Grand Theft Auto 5 or Oblivion Remastered.
These archives contain modified dynamic libraries, sometimes renamed with extensions like .ASI to resemble legitimate plugin formats.
When the user follows the installation instructions, the malicious library is placed in the same folder as the target game. If the game does not properly validate its libraries, the trojan loads automatically at startup.
In some cases, flaws in library search priorities are essential to the malware’s success, allowing it to hijack execution within the host application.

Once loaded, the malware establishes contact with a command-and-control server using encrypted communication. This process includes verifying encryption keys and checking timestamp consistency, which is meant to evade analysis and block antivirus detection.
The malware doesn’t stop with the initial payload. In more complex infections, it deploys additional trojans that embed themselves in Chromium-based browsers like Chrome, Edge, Opera, and Yandex.
