Operation Covert Access: Rust RAT Infiltrates Argentina’s Judiciary

Operation Covert Access is a targeted cyber-espionage campaign against Argentina’s judicial system that leverages spear-phishing ZIP attachments containing malicious LNK files to run hidden PowerShell commands and fetch a Rust-based Remote Access Trojan from GitHub; the RAT hides as msedge_proxy.exe, performs VM and analysis-tool checks to evade detection, supports modular commands for persistence and data theft, and includes encryption routines that could enable ransomware-like operations.
