Karakurt data extortion group: CISA issues alert

In a joint Cybersecurity Advisory by the FBI, the Cybersecurity and Infrastructure Security Agency (CISA), the Department of Treasury, and the Financial Crimes Enforcement Network (FinCEN), the four U.S. agencies warned businesses about the tactics, techniques, and procedures (TTPs) of the Karakurt data extortion group. Unlike ransomware groups, Karakurt does not encrypt data, it simply steals it. The group then threatens the victimized business with auctioning the sensitive data if the company does not pay the extortion fee. The alert says the fee typically ranges between $25,000 to $13,000,000 in Bitcoin.
