Threats Tagged 'remusstealer'

RemusStealer is a malware-as-a-service program exhibiting multiple similarities to LummaStealer, including anti-virtual machine checks, credential theft tactics, and Application-Bound Encryption bypass methods. A key distinction is RemusStealer's use of Ethereum smart contracts for C2 communications instead of Steam or Telegram dead drop resolvers. Written in Go, the stealer performs extensive system discovery, gathering information about antivirus products, hardware specifications, and operating systems. It employs hidden desktop environments to evade detection while launching Microsoft Edge and Brave browser processes on non-primary window stations to steal credential files. The malware establishes connections to suspicious domains ending in .shop or .biz and communicates with Ethereum-related infrastructure. This evolution demonstrates attackers' increasing sophistication in leveraging blockchain technology to masquerade malicious communications through smart contracts.
