🛡️CISA: Hackers Use AI to Exploit Siemens S7 Water PLCs
TL;DR
CISA, the FBI and the NSA warned Wednesday that attackers are using AI to write exploit scripts against Siemens S7 controllers in US water systems. The agencies tie the campaign to escalating activity by suspected Iranian operators.

Key Points
All Siemens S7 PLC models are in scope, covering energy, water, manufacturing and agriculture
AI is being used to find internet-exposed controllers and to reason about how the devices work
Possible outcomes named by CISA: downtime, safety incidents, equipment damage
Intrusions already reported at water facilities in Minnesota, Michigan, Arkansas, Georgia and New Jersey
Rural utilities are hit hardest because a few systems cover large service areas
Why It Matters
AI is not creating new OT vulnerabilities here, it is collapsing the cost of finding and weaponizing old ones, which changes the math on how long unpatched PLCs can stay online.
