Municipal water systems in several states have been targeted by hackers, prompting a warning from the FBI and the Environmental Protection Agency. The agencies have reported incidents of malicious activity that have disrupted water operations in at least seven states. The warning was issued in a public service announcement, although the states affected were not named.

This comes after a similar incident in Minnesota, where over 30 municipal water facilities were targeted. Further details on the incidents and the investigation are available from the source. The FBI and Environmental Protection Agency are urging utilities nationwide to be aware of the potential threat to critical water infrastructure.
