Iran-Linked Cyberattacks Disrupt U.S. Water Utilities

Core Event: Multi-State Hacks Target Municipal Water Systems
In the past week, municipal water and wastewater utilities in at least seven states experienced cyber intrusions that disabled remote monitoring and control functions. Sites in Michigan, Minnesota, New Jersey, Georgia and Wisconsin shifted to manual operation, preventing any interruption to drinking-water service. Federal investigators said the attacks exploited internet-exposed programmable logic controllers (PLCs) used to manage pumps, valves and chemical dosing.
Background & Context
Most U.S. water infrastructure predates modern networking. Roughly 97 % of the nation’s 151 000 water facilities are small, locally run entities that lack dedicated IT staff and were not built with cybersecurity in mind. When legacy control systems are connected to Wi-Fi or public-facing webpages, they become “low-hanging fruit” for attackers.
Data & Statistics
- EPA lists about 150 000 public water systems nationwide.
- 420 utilities voluntarily share cybersecurity information with federal partners.
- Since July 27, the FBI has received reports of incidents in at least seven states.
Official Statements & Responses
Federal agencies—including the FBI, CISA and the New Jersey Cybersecurity and Communications Integration Cell (NJCCIC)—issued alerts warning of “ongoing Iranian-affiliated” hacks and advised operators to remove direct internet connections from PLCs, enforce strong passwords and deploy firewalls.
President Donald Trump dismissed Iranian involvement, blaming Minnesota Governor Tim Walz and calling the claim “a distraction.”
NJCCIC spokesperson Christopher Thoresen said the two affected New Jersey utilities have been “secured with strengthened access controls.”
Criticism & Opposition
Caitlin Durkovich, a former assistant secretary for infrastructure protection, argued that the administration has “normalized” attacks on critical infrastructure, placing U.S. systems on the front lines of geopolitical conflict.
Joshua Corman, founder of I Am The Cavalry, warned that many water plants are exposed without passwords or firewalls.
On-the-Ground Reports
- In Braham, Minnesota, a hack knocked the town’s water supply offline for a few hours before operators restored service manually.
- New Jersey’s two unnamed municipal utilities shifted to manual control, maintaining uninterrupted drinking-water access.
- Clayton County, Georgia, briefly issued a boil-water advisory, while Columbus, Ohio, detected an intrusion but reported no service impact.
Conflicting Reports & Gaps
State and local officials have “tentatively concluded” that the attacks may trace back to Iran, citing the tactics and lack of ransom demand. The FBI has not publicly linked the intrusions to any nation-state, and some analysts note the methods could be mimicked by other actors. Attribution remains unconfirmed.

- “They are not equipped for dealing with … state-sponsored cyberattacks,” — Lennart Maschmeyer
- “They still have a lot of manual systems, so if they need to, they can disconnect and continue to operate in a manual state,” — Jeff Greene
