# Iran-Linked Hackers Force UK Power Plant Offline for Four Days

> Iran-linked hackers forced a small UK power plant offline for four days in July, the first such successful attack on British energy infrastructure, officials say.

Hackers linked to Iran's Islamic Revolutionary Guard Corps knocked a small British power plant offline for four consecutive days in July, UK officials confirmed this week. It is believed to be the first time Iran-affiliated hackers have successfully forced a UK energy facility to shut down entirely.

The National Cyber Security Centre and GCHQ investigated the breach, but the affected facility was small enough that it fell below legal reporting thresholds and was not named publicly. A UK government spokesperson said "at no point was there any risk to the broader national grid," noting the plant's output was "less than a rounding error" compared to national capacity. The NCSC reportedly handles at least four "nationally significant" cyberattacks every week.

Security analysts described the incident as a proof-of-concept demonstration rather than an attempt at widespread damage — a signal that Iran-linked groups can penetrate UK infrastructure at will. The disclosure comes as US officials separately warn that Iranian-linked hackers are using AI to target industrial control systems at water utilities.
