Seized Gentlemen Ransomware C2 Server Exposes 1,570 Victims — GPO Deployment Reveals Full Domain Compromise

Check Point Research's analysis of a seized SystemBC command-and-control server linked to The Gentlemen ransomware operation exposed 1,570+ victim IP addresses and documented the group's use of Group Policy Objects to deploy ransomware domain-wide. GPO-based distribution is a forensic marker that attackers achieved Domain Admin access days before encryption — defenders should treat it as an indicator of extended dwell time, not a starting point.
