The claim is false because the available reporting describes a cyberattack on Minnesota water systems whose suspected origin is Iranian, while Minnesota officials have not publicly attributed it to Minnesota actors.
Minnesota (not Iran) is behind cyberattacks on Minnesota

U.S. investigating if Iran was behind cyberattack on water systems in 7 states, including Minnesota - CBS News

Key Evidence
Multiple July 30, 2026 reports said U.S. Officials believed Iran was likely responsible, although the assessment was preliminary. CBS News, AP, and Minnesota IT Services reporting also made clear that Minnesota had not publicly identified a perpetrator; none of the provided sources says Minnesota itself conducted the attacks.
What the Evidence Shows
The statement appears to reject the reported Iranian connection and assert that Minnesota itself was responsible. The provided evidence does not support that assertion.
- CBS News and the Associated Press reported that more than 30 Minnesota community water systems were affected, but that investigators had not publicly identified the perpetrator.
- Later reporting dated July 30, 2026, including The New York Times, Valley News Live, WIRED, and Fox News, said U.S. Officials considered Iran the likely source. Those reports also emphasized that the assessment was preliminary and had not been formally announced or conclusively established.
- Minnesota IT Services reportedly stated that Minnesota had not attributed the activity to a specific actor. That means the Iranian attribution remained an investigative assessment rather than a final public finding; it does not provide evidence that Minnesota was behind the attacks.
- The Reddit result is secondary and points to the WIRED reporting, so it adds little independent evidentiary weight.
Accordingly, the evidence supports describing the claim as unsupported and contrary to the available reporting. The most accurate formulation is that Iranian involvement was considered likely by some U.S. Officials, but the investigation was still active and attribution was not final.
