Infrastructure Market: US warns AI-aided hackers target Siemens S7 water systems
U.S. security agencies including CISA, the FBI and the NSA issued an advisory saying hackers are actively exploiting Siemens S7 programmable logic controllers (PLCs) used in critical infrastructure. The agencies warned attackers are using AI to generate exploit scripts that leverage publicly available information to find and compromise out-of-date or poorly secured PLCs, with water supply and wastewater systems across multiple U.S. states already affected. CISA reiterated long-standing guidance to keep such devices disconnected from the internet and cautioned rural communities are often more vulnerable. The advisory follows a series of recent intrusions attributed to suspected Iranian-linked actors targeting U.S. water and energy providers.
A technical advisory from major U.S. security agencies warns of AI-enabled attacks against widely deployed industrial controllers in critical water infrastructure across multiple states, posing safety and operational risks and showing AI's growing role in automating cyber exploitation.
