Original release date: February 24, 2022
CISA, the Federal Bureau of Investigation (FBI), U.S. Cyber Command Cyber National Mission Force (CNMF), the United Kingdom’s National Cyber Security Centre (NCSC-UK), and the National Security Agency (NSA) have issued a joint Cybersecurity Advisory (CSA) detailing malicious cyber operations by Iranian government-sponsored advanced persistent threat (APT) actors known as MuddyWater.
MuddyWater is conducting cyber espionage and other malicious cyber operations as part of Iran’s Ministry of Intelligence and Security (MOIS), targeting a range of government and private-sector organizations across sectors—including telecommunications, defense, local government, and oil and natural gas—in Asia, Africa, Europe, and North America.
CISA encourages users and administrators to review the joint CSA: Iranian Government-Sponsored Actors Conduct Cyber Operations Against Global Government and Commercial Networks. For additional information on Iranian cyber threats, see CISA’s Iran Cyber Threat Overview and Advisories webpage.
