Several states report cyberattacks as spy agencies suspect Iran is targeting water

Federal authorities are warning that critical infrastructure systems in the United States could be at risk after at least seven states reported cyberattacks that interrupted their water or wastewater operations this week.

According to a joint alert from the FBI and the Environmental Protection Agency, "malicious cyber actors" have been remotely tampering with some water systems' internet-connected programmable logic controllers, or PLCs, causing loss of water pressure and flooding.
