NSHC observed SectorA activity during December 2025 involving credential theft, remote access, and financially motivated targeting of finance, technology, and government environments. The DPRK-linked section highlights LummaC2 and OtterCookie use, WinRAR vulnerability exploitation, fake job interview and tax-authority social engineering, and malicious npm package activity aimed at developer and cryptocurrency-related data. SectorA also abused legitimate services such as GitHub, Dropbox, Slack, VPNs, and shared C2 infrastructure to support delivery, command-and-control, and exfiltration. The report places these findings in a broader monthly trend where some North Korea-linked operations blur state objectives with cybercriminal methods.
