Rust-based VENON banking malware targets 33 banks in Brazil
🛡️ Brazilian cybersecurity firm ZenoX disclosed a Rust-based banking trojan named VENON that targets Windows users and 33 financial and digital-asset platforms. The threat chain uses DLL side-loading and a PowerShell-delivered ZIP to drop a malicious DLL that performs nine evasion techniques (anti-sandbox checks, indirect syscalls, ETW and AMSI bypasses) before executing payloads. VENON fetches configuration from Google Cloud Storage, installs a scheduled task, and connects to a WebSocket C2 while employing banking overlays, active window monitoring, and an Itaú-specific LNK hijack implemented via embedded VBS; it also supports a remote uninstall to restore altered shortcuts. ZenoX noted the Rust code reflects knowledge of Latin American trojans and appears to have been rewritten or expanded with the aid of generative AI.
