U.S. sanctions six Iran-linked MOIS cyber actors over critical-infrastructure intrusions and U.S. government email breaches

The U.S. sanctioned six Iranian cyber actors it says carried out attacks on critical infrastructure and breached U.S. government and U.N. email accounts. Treasury says the men worked for or with Iran’s Ministry of Intelligence and Security, and since 2023 targeted energy, defense, healthcare, technology, finance, and government organizations, including the Department of Labor, the Federal Energy Regulatory Commission, and multiple U.N. entities.
Why it matters: This is a concrete attribution and sanctions action tied to intrusions affecting critical infrastructure and government networks, which helps defenders track the actors and sectors at risk. Organizations in the named sectors should review Iranian threat activity, harden email and remote access, and check for signs of compromise.
