Recent research from Dr.Web has identified a malware family called Trojan.Scavenger that targets Windows users by disguising itself as game performance boosters or enhancements. This malware exploits vulnerabilities in games like Grand Theft Auto 5 and Oblivion Remastered, typically arriving as modified dynamic libraries with extensions like .ASI. When installed, it can automatically load if the game does not validate its libraries properly. Once activated, it connects to a command-and-control server using encrypted communication and can deploy additional trojans that infiltrate Chromium-based browsers, disrupting their security features and replacing legitimate extensions with malicious ones. This puts applications at risk, including crypto wallets like MetaMask and Phantom, and password managers like Bitwarden and LastPass, as the malware captures sensitive information and sends it to attackers. Exodus wallet is also targeted, with the malware extracting critical JSON entries for private key generation. To mitigate these risks, users are advised to avoid downloading unofficial content from unverified sources, keep antivirus software updated, manage social media interactions carefully, and verify file paths and digital signatures.
