ThreatLabz has identified MLTBackdoor, a highly obfuscated post-exploitation framework delivered via ClickFix social engineering lures. The malware utilizes Mixed Boolean-Arithmetic (MBA), Control Flow Flattening (CFF), and indirect system calls to evade detection, while maintaining persistence and control through a custom encrypted protocol, a Domain Generation Algorithm (DGA), and a Beacon Object File (BOF) loader.
