The Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) have issued an advisory about Chinese Ministry of State Security (MSS)-affiliated cyber threat actors targeting U.S. government agencies. Through the National Cybersecurity Protection System, CISA has observed Chinese MSS-affiliated cyber threat actors operating from the People’s Republic of China using commercially available information sources and open-source exploitation tools.
CISA leveraged the MITRE Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK®) and Pre-ATT&CK frameworks to characterize the tactics, techniques, and procedures (TTPs) used by Chinese MSS-affiliated actors. CISA encourages users and administrators to review the joint cybersecurity advisory and CISA’s Chinese Malicious Cyber Activity page for more information.
