More than 30 water systems across Minnesota were hit by cyberattacks on 26 and 27 July, and investigators are examining whether Iranian hackers were behind them. The FBI and Cybersecurity and Infrastructure Security Agency had already warned the previous week that Iranian-linked groups were actively targeting water infrastructure. No residents lost access to safe drinking water, though the city of Braham — about 70 miles north of Minneapolis — briefly asked residents to conserve water after attackers disabled the operating controls for its well and treatment plant. Plymouth's water communications were also knocked offline, and restored by the afternoon of 28 July. Investigators haven't officially named a suspect. But Cynthia Kaiser, former deputy assistant director of the FBI's cyber division, says Iran's track record and motive make it the obvious starting point: most credible researchers, she argues, would be right to treat it as Iran until proven otherwise. _Updated 11 Aug 2026: The FBI has since confirmed the campaign targeted water systems in at least seven states, including Michigan and Georgia._ **Source:** [SecurityWeek](https://www.securityweek.com/cyberattacks-on-minnesota-water-systems-investigated-as-officials-warn-about-iranian-hackers/) Share this article [![Share on facebook](https://codekeeper.co/hubfs/Codekeeper%202025/Icons/Blog%20-%20Facebook.svg)](http://www.facebook.com/share.php?u=https%3A%2F%2Fcodekeeper.co%2Fticker%2Fminnesota-water-systems-cyberattack-iranian-hackers%3Futm_medium%3Dsocial%26utm_source%3Dfacebook) [![Share on linkedin](https://codekeeper.co/hubfs/Codekeeper%202025/Icons/Blog%20-%20Linkedin.svg)](http://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fcodekeeper.co%2Fticker%2Fminnesota-water-systems-cyberattack-iranian-hackers%3Futm_medium%3Dsocial%26utm_source%3Dlinkedin) [![Share on twitter](https://codekeeper.co/hubfs/Codekeeper%202025/Icons/Blog%20-%20X.svg)](https://twitter.com/intent/tweet?original_referer=https%3A%2F%2Fcodekeeper.co%2Fticker%2Fminnesota-water-systems-cyberattack-iranian-hackers%3Futm_medium%3Dsocial%26utm_source%3Dtwitter&url=https%3A%2F%2Fcodekeeper.co%2Fticker%2Fminnesota-water-systems-cyberattack-iranian-hackers%3Futm_medium%3Dsocial%26utm_source%3Dtwitter&source=tweetbutton&text=) [![Share on email](https://codekeeper.co/hubfs/Codekeeper%202025/Icons/Blog%20-%20Mail.svg)](mailto:?subject=Check%20out%20https%3A%2F%2Fcodekeeper.co%2Fticker%2Fminnesota-water-systems-cyberattack-iranian-hackers%3Futm_medium%3Dsocial%26utm_source%3Demail%20&body=Check%20out%20https%3A%2F%2Fcodekeeper.co%2Fticker%2Fminnesota-water-systems-cyberattack-iranian-hackers%3Futm_medium%3Dsocial%26utm_source%3Demail) ![Copy link](https://codekeeper.co/hubfs/Codekeeper%202025/Icons/Blog%20-%20Copy.svg) ![blog_book_a_demo_cta_3x](https://codekeeper.co/hubfs/_sized/Codekeeper%202025/blog_book_a_demo_cta_3x-768x512.webp) Have questions about protecting your software?
