Law enforcement has seized the dark web extortion sites of the BlackSuit ransomware operation, which has targeted and breached the networks of hundreds of organizations worldwide over the past several years.
The U.S. Department of Justice confirmed the takedown in an email earlier today, saying the authorities involved in the action executed a court-authorized seizure of the BlackSuit domains.
Earlier today, the websites on the BlackSuit .onion domains were replaced with seizure banners announcing that the ransomware gang's sites were taken down by the U.S. Homeland Security Investigations federal law enforcement agency as part of a joint international action codenamed Operation Checkmate.
"This site has been seized by U.S. Homeland Security Investigations as part of a coordinated international law enforcement investigation," the banner reads.
BleepingComputer has confirmed that the seized sites include the dark web data leak blogs and negotiation sites used to extort victims into paying a ransom demand.
