Iran-Linked Cyberattack Targets 30+ Minnesota Water Systems
A cyberattack this week compromised over 30 municipal water systems across Minnesota, with a senior law enforcement official indicating the incident bears the hallmarks of Iran-backed hackers. While U.S. and state authorities have not publicly attributed the attack to a specific group, the timing aligns with recent federal warnings about Iranian threat actors targeting critical infrastructure.
The breach occurred days after the U.S. issued alerts regarding heightened cyber threats to water and wastewater systems. Federal agencies have since urged operators to bolster defenses, though no further details on the attack’s methods or impact have been disclosed. The investigation remains ongoing.
