US Confirms Shutdown of BlackSuit Ransomware That Hacked Over 450 Organizations

U.S. and international law enforcement carried out Operation Checkmate to dismantle the BlackSuit ransomware operation — a successor to the Royal group blamed for attacks on over 450 organizations across healthcare, education, public safety, energy, and government sectors and for extorting more than $370 million via double extortion — by seizing servers, domains, and digital assets; authorities emphasized cross-border cooperation and urged continued vigilance despite the disruption of the group’s infrastructure.
