Original release date: September 21, 2022

CISA and the Federal Bureau of Investigation (FBI) have released a joint Cybersecurity Advisory (CSA), Iranian State Actors Conduct Cyber Operations Against the Government of Albania, detailing malicious cyber operations that included ransomware and disk wiper, rendering websites and services unavailable. The advisory indicates Iranian state cyber actors acquired initial access to the victim’s network approximately 14 months before launching the destructive cyber attack, periodically accessing and exfiltrating email content.

Joint CSA: Iranian State Actors Conduct Cyber Operations Against the Government of Albania outlines tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) likely used by Iranian state cyber actors as recently as July 2022. CISA and FBI encourage users and administrators to review the advisory and apply the recommended mitigations to limit the risk of compromise.

U.S. Government Attributes Cyberattacks on SATCOM Networks to Russian State-Sponsored Malicious Cyber Actors

05/10/2022 09:27 AM EDT

Original release date: May 10, 2022

CISA and the Federal Bureau of Investigation (FBI) have updated the joint cybersecurity advisory, Strengthening Cybersecurity of SATCOM Network Providers and Customers, originally released March 17, 2022, with U.S. government attribution to Russian state-sponsored malicious cyber actors. The United States assesses Russia launched cyberattacks in late February against commercial satellite communications networks to disrupt Ukrainian command and control during the Russia invasion, and those actions had spillover impacts into other European countries.

CISA is working with both international and JCDC partners to strengthen our collective cybersecurity resilience—especially in the critical infrastructure that governments and citizens rely on—and to protect against and respond to malicious cyber activity.  We continue to urge public and private sector partners to review and implement the guidance contained in U.S. government cybersecurity advisories, including Strengthening Cybersecurity of SATCOM Network Providers and Customers, the January 2022 cybersecurity advisory on Protecting VSAT Communications, and the April 2022 cybersecurity advisory on Russian State-Sponsored and Criminal Threats to Critical Infrastructure. CISA also recommends partners review the CISA Shields Up, Shields Up Technical Guidance, and Russia webpages to stay current on the preventive measures that can help guard against Russian cyber threats and tactics.
