AI Summary
KREMLIN is a Brazilian banking malware operation active since May 2025 that targets Chromium-based browsers to steal credentials, session tokens, and sensitive data. It uses multi-stage JavaScript loaders, C++ installers, and malicious browser extensions, evading sandbox detection by checking hardware properties and process names. The malware leverages Ethereum smart contracts as dead drop resolvers to dynamically update C2 infrastructure and employs DLL sideloading via a legitimate SentinelOne binary. It installs a malicious extension named 'AVSync System Inc.' that exfiltrates browser data through WebSocket and HTTP-based polling mechanisms.
