Spear-Phishing Campaign Abuses Argentine Federal Court Rulings to Deliver Covert RAT

**Operation Covert Access:** Seqrite Labs documents a targeted spear-phishing campaign against Argentina’s judicial institutions that uses weaponized LNK files and a decoy court PDF to silently deploy a Rust-based RAT with robust anti-analysis checks, C2 communications (default 181.231.253.69:4444), modular post-exploitation features (credential harvesting, DLL-based ransomware/stealer modules), and persistent registry/scheduled-task techniques; IOCs and mitigation recommendations are provided.
