Federal agencies said there is an “active threat” targeting critical infrastructure organizations using AI-generated exploit scripts, in what they called an “evolution” in capabilities.

Organizations were urged to treat Wednesday’s advisory “with urgency” and initiate response efforts centered around programmable logic controllers (PLCs) — tools used by the energy, water and agricultural industries to control pumps and monitor processes.

The National Security Agency (NSA), FBI and other federal agencies said the campaign is targeting Siemens S7 Series PLCs and was being fueled by “AI-assisted development” alongside exploitation of known vulnerabilities.
