US: Suisun City hit by malware attack

Suisun City, California, declared a state of emergency after a malware attack disrupted the 911 system, police and fire dispatch, and other essential municipal services.

Impact on local services

The city did not provide other concrete effects in the available material, but the disruption reached functions critical to emergency response and municipal operations. The emergency declaration reflects the pressure these incidents can place on local governments when communication and dispatch systems are affected.

A wave of water incidents

At the same time, the FBI and the EPA issued a joint alert saying that since July 27, 2026, incidents had been reported at water and wastewater services in at least seven U.S. states, and that some of that activity had degraded water operations. Tenable reported on those attacks in Minnesota and said there was no public attribution to any specific actor in that case.

The BBC added that, beyond Minnesota, local authorities in New Jersey, South Dakota, and Georgia said they had been hit in a similar wave of incidents against water systems. El Español reported that U.S. authorities had not publicly attributed the campaign to any specific gang and that the investigation still lacked definitive forensic evidence.

Response and preventive steps

Moncloa reported that, according to the FBI and EPA advisory, some plants were operating manually and boil-water notices were issued in specific areas, although contamination of the supply had not been confirmed. In that context, Diario Bitcoin reported that New York allocated $9 million to protect 153 water systems from cyberattacks.

The available material points to two clear lines. On one hand, a California city had to declare an emergency after an attack that cut off essential services. On the other, multiple water utilities in different states came under pressure in a campaign whose public attribution remains unconfirmed.
