U.S. Sanctions LockBit Leader, Disrupts a Quarter of All Ransomware Attacks

The Treasury Department designated Dmitry Yuryevich Khoroshev as LockBit's leader and imposed sanctions on him and his network. LockBit operated as a ransomware-as-a-service platform—essentially a criminal business renting attack tools to other criminals—and was behind roughly 25% of recorded ransomware incidents. The disruption marks one of the most significant enforcement actions against ransomware to date.
