Three Minnesota water utilities report cyber incidents days after CISA PLC warning

Three Minnesota cities reported cyber incidents affecting municipal water technology on Monday: South St. Paul, Braham, and Plymouth.

Edit: A fourth water utility in Maple Plain was impacted.

All three cities said drinking water remained safe. Braham officials also said they were told at least four other communities were attacked “with the same result,” suggesting at least two affected municipalities have not been publicly named.

The timing is notable because CISA and federal partners updated an advisory five days earlier warning that Iranian-affiliated actors were targeting internet-connected programmable logic controllers used across U.S. critical infrastructure. The advisory describes operational disruptions involving control configurations, sensor readings and interfaces.

That said, there is currently no public evidence connecting these Minnesota incidents to the activity in the CISA advisory. The cities have not disclosed the affected vendors, PLC models, access methods or threat actors, and officials have not confirmed that the three incidents share a common source.

For people working in water or operational technology security, do the reported symptoms resemble the activity CISA described, or is the available information still too limited to draw a meaningful comparison?

Cyberattack halts U.S. production at Coca-Cola’s fairlife dairy business

Coca-Cola’s fairlife dairy business suspended U.S. production after a ransomware incident involving production-related systems, prompting the company to activate its incident response plans, notify law enforcement and begin restoring affected operations. The company said product quality and safety were not affected, and Canadian production continued uninterrupted, but it did not identify which U.S. facilities or systems were directly compromised. Coca-Cola has not disclosed whether data was stolen, files were encrypted or a ransom demand was received, and no ransomware group had publicly claimed responsibility or been attributed to the attack at the time of publication.

Greene County, Georgia, cybersecurity incident disrupts services

Greene County, Georgia, took its government network offline after discovering a cybersecurity incident on July 9, disrupting payment processing and services across tax, court and administrative offices. County officials said their contracted technology provider disconnected servers to contain the incident while cybersecurity specialists work to rebuild systems. The outage affected numerous county departments, including the courthouse, tax offices, elections and public works, though officials said the 911 communications system and the Greene County Sheriff’s Office remained fully operational. The county has found no evidence that information was accessed or removed from its systems, but the investigation remains ongoing and officials have not disclosed the nature of the incident, identified a threat actor or provided a timeline for restoring services.
