A suspected Iran-linked cyberattack forced a small UK power plant offline, coinciding with a wave of digital intrusions that disrupted American water utilities across 12 states. The UK government confirmed the incident to The Register, stressing that the affected facility was a "small-scale energy generator" and that there was no risk to the wider energy system, though the episode is believed to be the first disruptive Iranian cyberattack of its kind in Britain.

The Telegraph, which first reported the story, said the plant was shut down for four days, though officials have not named the site or formally attributed the attack to Iran. Energy Minister Michael Shanks said his department briefed energy company CEOs and issued security advice following the incident. It follows similar suspected Iranian intrusions in late July that hit more than 30 water facilities in Minnesota and spread to at least 11 other US states, largely via internet-connected programmable logic controllers; federal agencies have since warned that attackers are now using AI-generated exploitation scripts to target Siemens S7 PLCs across critical infrastructure sectors.
