What happened
CISA disclosed that over 100 internet-exposed water and wastewater systems across at least a dozen US states were targeted in July 2026, primarily via PLCs connected directly to cellular modems. The campaign is suspected to be linked to Iran but remains unattributed, and a separate federal warning notes attackers are now using AI-generated exploitation scripts against Siemens S7 Series PLCs.
Why it matters
The only AI-relevant detail is that attackers are reportedly using AI-generated exploitation scripts to break into Siemens S7 PLCs — a signal that AI-assisted vulnerability exploitation is moving from theory to observed critical-infrastructure attacks. For builders shipping AI tools or agents, this is a watch-item, not an action-item; there is no specific tool, patch, or workflow to change here.
Discussion angle
Whether AI-generated exploitation scripts represent a meaningful escalation in OT/ICS attacks or are just automation of existing known-vulnerability exploitation — and what that means for AI safety narratives builders may face from regulators.
