CISA and FBI Release Advisory on ALPHV Blackcat Affiliates

Today, CISA and the Federal Bureau of Investigation (FBI) released a joint Cybersecurity Advisory (CSA), #StopRansomware: ALPHV Blackcat, to disseminate known ALPHV Blackcat affiliates’ tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) identified through FBI investigations as recently as Dec. 6, 2023. The advisory also provides updates to the FBI FLASH BlackCat/ALPHV Ransomware Indicators of Compromise released April 19, 2022.

ALPHV Blackcat affiliates have extensive networks and experience with ransomware and data extortion operations. FBI investigations, as of September 2023, place the number of compromised entities at over 1000—over half of which are in the United States and approximately 250 outside the United States.

CISA and FBI encourage critical infrastructure organizations to review and implement the mitigations provided in the joint CSA to reduce the likelihood and impact of ALPHV Blackcat ransomware and data extortion incidents. For more information, see CISA’s #StopRansomware webpage, which includes the updated #StopRansomware Guide.
