Technical Analysis of MLTBackdoor

The report provides a technical analysis of MLTBackdoor, a sophisticated Windows backdoor observed distributed via a ClickFix lure and a date-based DGA; it details the full infection chain, extensive LLVM-based obfuscation (MBA, CFF, stack-built strings), indirect system-call trampolines, DJB2 API hashing, anti-analysis checks, a BOF loader compatible with Cobalt Strike imports, and a custom AES-256-GCM-over-TLS protocol using ECDH (P-256) with fixed path and User-Agent to blend in with legitimate traffic.
