NSHC's November 2025 threat actor intelligence report summarizes activity from 82 observed groups between 21 October and 20 November 2025, with SectorA among the most active tracked clusters. The SectorA section describes targeting of technology, defense, aerospace, Web3, mobile, cryptocurrency, and IT personnel through job-offer impersonation, fake coding tests, video-call impersonation, messenger approaches, spear-phishing documents, LNK and VHDX chains, and trojanized development projects. The group is described abusing legitimate platforms including GitHub, Bitbucket, Telegram, LinkedIn, and WhatsApp to distribute malicious scripts, backdoors, and information-stealing modules across macOS, Windows, and Android. The report emphasizes multi-stage attack chains, DLL side-loading, obfuscated scripts, LOLBins, and encryption such as ChaCha20, AES-128, and RC4 to hide payload decryption and C2 communications.
