InfoSecurity Magazine reports:

BlackSuit’s dark web data leak site and private negotiation panels have been taken offline in what appears to be a large-scale law enforcement operation.

On July 24, the ransomware group’s leading site, usually accessible via The Onion Router (TOR), displayed a banner stating, “This site has been seized by U.S. Homeland Security Investigations as part of a coordinated international law enforcement investigation.”

The international coalition included the US, the UK, Ukraine and Latvia, as well as Europol and Bitdefender, a private cybersecurity firm based in Romania and the US.
