NSA, CISA, FBI, DOE, and EPA Warn of Active AI-Assisted Attacks on Siemens S7 PLCs

U.S. agencies (CISA, NSA, FBI, DOE, EPA) warn of an active AI-assisted campaign targeting Siemens S7 PLCs across multiple critical infrastructure sectors; attackers use public scanning services to find Internet-exposed controllers and run AI-generated exploitation scripts (using legitimate snap7 libraries) to perform reconnaissance and pre-position for potential disruptive writes, with guidance provided for detection and mitigation.
