Iran is the prime suspect in a series of cyberattacks targeting municipal water systems across at least a dozen U.S. states.
A series of cyberattacks targeting municipal water systems across at least a dozen U.S. states has led federal investigators to tentatively conclude that Iran is the prime suspect. The attacks exploited vulnerabilities in internet-connected programmable logic controllers (PLCs) used to remotely monitor and control pumps and valves. While some systems, such as those in New Jersey and Minnesota, shifted to manual operations to maintain service, others, like the Clayton County Water Authority in Georgia, briefly issued boil-water advisories. Despite the disruptions, officials confirmed that drinking water remained safe throughout the incidents. The FBI and the Environmental Protection Agency issued a public warning to critical infrastructure operators, advising them to secure PLCs with firewalls and stronger passwords. The administration announced that the attacks occurred during a period of heightened tension with Iran. However, during a Cabinet meeting, President Trump baselessly claimed that Minnesota was responsible for the attacks rather than Iran. This highlights a growing concern regarding the nation's aging infrastructure and its vulnerability to modern cyber threats.
