Last Revised

The Federal Bureau of Investigation (FBI) and the United States Secret Service (USSS) have released a joint Cybersecurity Advisory (CSA) identifying indicators of compromise associated with BlackByte ransomware. BlackByte is a Ransomware-as-a-Service group that encrypts files on compromised Windows host systems, including physical and virtual servers.

CISA encourages organizations to review the joint FBI-USSS CSA and apply the recommended mitigations.
