Supplemental Info:


The Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), the Department of Defense Cyber Crime Center (DC3), and the National Security Agency (NSA) strongly urge organizations to remain vigilant for potential targeted cyber activity against U.S. critical infrastructure and other U.S. entities by Iranian-affiliated cyber actors.
