CISA, the Federal Bureau of Investigation (FBI), and the National Security Agency (NSA) have released a joint Cybersecurity Advisory (CSA) highlighting regular targeting of U.S. cleared defense contractors (CDCs) by Russian state-sponsored cyber actors. These CDCs support contracts for the U.S. Department of Defense and Intelligence Community. The CSA provides incident response and remediation recommendations as well as mitigations to reduce the risk of compromise.
CISA encourages all critical infrastructure organizations to review the joint CSA: Russian State-Sponsored Cyber Actors Target Cleared Defense Contractor Networks to Obtain Sensitive U.S. Defense Information and Technology and apply the necessary mitigations. For more information on Russian state-sponsored malicious cyber activity see CISA's Russia Cyber Threat Overview and Advisories page.
