Cyberattacks hit water facilities in seven states across the US
The FBI has issued a warning after water facilities from seven states reported that they were hacked.
Cyberattacks have targeted water facilities in seven US states, according to the FBI and the Environmental Protection Agency (EPA). Seven water and wastewater utility companies experienced degraded operations since July 27, 2026. Hackers target Programmable Logic Controllers (PLCs) by changing IP addresses and passwords, disrupting monitoring and control capabilities.
The FBI recommends secure gateways, firewalls, stronger passwords, and access control lists to protect systems. Loss of pressure and flooding could result from attacks, causing untreated groundwater to infiltrate pipes. Recently, more than 30 municipal water facilities in Minnesota were infiltrated, possibly linked to Iranian meddling, though investigation is ongoing.
The US Cybersecurity and Infrastructure Security Agency (CISA) has also warned of Iranian-affiliated hackers targeting water infrastructure.
