OVERCAST: Tracking 1,900 Nation-State RDP Nodes Across Cloudzy's C2P Ecosystem

We received 50 validated IPs linked to a suspected Russian state-sponsored APT, profiled them through ClusterHawk, and extracted a common fingerprint. Pivoting that profile against internet scanning data surfaced about 1,900 matching assets across 15 countries. We call this tracking effort OVERCAST.

SideWinder's Click Once campaign - independent validation with ClusterHawk

We confirm Trellix's reporting on SideWinder's PDF ClickOnce chain and targets. Testing the method, we pivoted on VirusTotal-communicated IPs and separated CDN/search noise (about 85%) from a compact nginx micro-cluster (about 15%), then built ready-to-run SIEM/Sigma and Shodan/Censys hunts.
