The record
Written from the 1 report below. Nothing here is unsourced.
- A coordinated cyberattack hit operational technology at more than 30 community water systems in Minnesota on July 26 and 27, causing plant outages and communications failures in several cities, including Braham, Plymouth, South St. Paul and Maple Plain.
- Residents in Braham were asked to minimize water use while its plant was offline, though the state said on July 28 it was not aware of any active requests to change drinking-water use.
- Minnesota IT Services is working with federal agencies including CISA, the FBI and the EPA to contain the incident and investigate.
- No attacker has been identified, but security firm Tenable noted similarities to Iranian-affiliated hacking of water systems, which officials have not confirmed.
What to watch next
- Whether MNIT finalizes attribution or identifies the vulnerability, access method, or affected controllers used in the attacks
- Whether any official link is established between the Minnesota incidents and the Iranian-affiliated campaign targeting programmable logic controllers
- Any new requests for residents to change water use or further operational disruptions as the investigation continues
