Michigan has reported cyberattacks on nine of its water systems, following similar incidents in Minnesota. An official stated that all systems are operating safely. The source of the attacks is currently being investigated.

The reports in Michigan emerged after a federal cyber alert was issued on Tuesday, warning of attempts to tamper with water system technology. The state then received reports from several communities indicating activity consistent with the federal alert. Further details on the investigation and the cyberattacks are available from the source.

The incidents have occurred amid warnings of Iranian hackers targeting water systems, with over 30 systems affected in Minnesota earlier this week.
