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.
