This was in Reuters: “US warns that hackers are carrying out disruptive attacks on water systems”

The U.S. government is warning state governors that foreign hackers are carrying out disruptive cyberattacks against water and sewage systems throughout the country.

In a letter released Tuesday, National Security Advisor Jake Sullivan and Environmental Protection Agency Administrator Michael Regan warned that “disabling cyberattacks are striking water and wastewater systems throughout the United States.”

The letter singled out alleged Iranian and Chinese cyber saboteurs. Sullivan and Regan cited a recent case in which hackers accused of acting in concert with Iran’s Revolutionary Guards had disabled a controller at a water facility in Pennsylvania. They also called out a Chinese hacking group dubbed “Volt Typhoon” which they said had “compromised information technology of multiple critical infrastructure systems, including drinking water, in the United States and its territories.”

“These attacks have the potential to disrupt the critical lifeline of clean and safe drinking water, as well as impose significant costs on affected communities,” the letter said.

Russia is preparing to mount cyber attacks on Britain’s “critical infrastructure” including energy networks, the emergency services and the armed forces, GCHQ and the FBI have warned in the wake of the Syria air strikes.
