BlackSuit ransomware extortion sites seized in Operation Checkmate

Law enforcement executed a coordinated international seizure of BlackSuit ransomware dark web domains and negotiation sites (Operation Checkmate), disrupting data leak blogs and extortion infrastructure; the report also traces BlackSuit’s evolution from Quantum/Royal, its ties to Conti, the large scale of its extortion activity (hundreds of victims and over $500M in demands), and Cisco Talos’ assessment that the group may rebrand as Chaos.
