Frequently asked questions about the active threat to Siemens S7 Series PLCs
US government agencies warn that unattributed actors using AI-generated exploit scripts are targeting internet-exposed Siemens S7 PLCs in critical infrastructure.
A joint advisory from multiple U.S. government agencies warns that threat actors are exploiting known weaknesses and unnecessary internet exposure of Siemens S7 Series PLCs for reconnaissance and possible pre-positioning for future disruptive attacks. The attackers use AI to generate and refine exploit scripts faster than manual development would allow, lowering the technical bar for ICS attacks. There is no single patch, so defenders must reduce internet exposure and improve monitoring of ICS environments.
