Cyberattack Shuts Down UK Power Plant

October 1, 2026

INCIDENT

As suspected Iranian-based hackers hit water facilities in 12 states in the United States, the same country also ended up linked shutting down a UK power plant for four days, government officials said.
The incident involved a small-scale energy generator, according to the UK government, which said that at no point was there a risk to the wider energy system. However, it marks an apparent escalation in the threat posed by Iran after the UK said it had given permission for the U.S. to launch “defensive” operations against Tehran from British bases.
The incident took place at the same time as a series of attacks on U.S. water infrastructure last month, which affected 12 states.
Iran’s Islamic Revolutionary Guard Corps (IRGC) is suspected in the attack
