US Government Agency Paid $1M to Data Extortion Group Kairos

• •A U.S. government agency paid $1 million to Kairos to prevent data leaks.
• •The extortion involved no encryption, focusing instead on keeping stolen files private.
• •The incident may be linked to Union County, Ohio, which experienced a data breach affecting over 45,000 individuals.

A U.S. government entity reportedly paid $1 million to the Kairos extortion group to prevent the public release of sensitive data. The payment was revealed in a Ransom-ISAC case study, which utilized a leaked negotiation chat and blockchain analysis. The incident appears to involve Union County, Ohio, although neither the county nor Kairos has confirmed this link. The extortion group did not employ traditional ransomware tactics, as there was no encryption or demand for a decryption key. Instead, they threatened to publish stolen files, including sensitive personal information from approximately 45,487 individuals. The negotiation lasted a month, with the initial demand set at $3 million, which was eventually settled at $1 million. The payment was made in bitcoin and subsequently laundered through various wallets. This case illustrates the evolving nature of ransomware, which increasingly involves extortion without encryption.
