Fake Notepad++ Plugin Delivers MATCHBOIL.V2 in UAC-0099 Attacks
- Engineer — Learn: Social engineering via trojanized software plugins is a recurring delivery vector; audit Notepad++ plugin directories on developer and admin workstations for unexpected DLLs, but no patch exists and no KEV or PoC signals elevate this to urgent action.
- SOC/IR — Plan: UAC-0099 is an active Russia-aligned actor with evolving delivery chains; build or tune detections for anomalous files dropped into Notepad++ plugin directories and monitor for MATCHBOIL.V2 indicators once CERT-UA publishes full IOC sets.
- Leader — Learn: Russia-aligned UAC-0099 campaign primarily flagged by CERT-UA; relevant context for organizations with Ukraine exposure or in sectors targeted by Russian threat actors, but no board-level event or vendor-breach action required.
