Zscaler’s ThreatLabz discovered a case in early 2024 where a victim paid $75 million to the group. The list of companies that reportedly paid large ransoms in the past include CNA Insurance ($40 million), CDK Global ($25 million) and Change Healthcare ($22 million).
“In most cases, the Dark Angels group steals a vast amount of information, typically in the range of 1-10 TB. For large businesses, the group has exfiltrated between 10-100 TB of data, which can take days to weeks to transfer.” reads the report. “The highest-profile attack conducted by Dark Angels was in September 2023, when the group breached an international conglomerate that provides solutions for building automation systems among other services. Dark Angels demanded a $51 million ransom, claimed to have stolen over 27 TB of corporate data, and encrypted the company’s VMware ESXi virtual machines. A RagnarLocker ransomware variant was used to encrypt the company’s files during the attack.”
Researchers from blockchain intelligence firm Chainalysis confirmed that early this year they saw the largest ransomware payment ever at $75M.
