FBI investigates as Michigan joins Minnesota in reporting cyberattacks on its water systems

Michigan has reported cyberattacks on nine of its water systems, following similar incidents affecting over 30 systems in Minnesota earlier this week. The FBI is investigating the source of these attacks, which occurred amid warnings from U.S. agencies about Iranian hackers targeting water and wastewater systems. While Michigan officials stated all affected systems operated safely and issues were addressed by local operators, the FBI has not identified a culprit. These attacks highlight the vulnerability of critical infrastructure, which often lacks robust cybersecurity measures. In Minnesota, the attacks primarily targeted technology used for remote monitoring and control, with one city briefly asking residents to minimize water use due to an offline plant.
