Hackers linked to Iran successfully shut down a small British power plant for four days, marking the first known cyberattack of its kind against UK energy infrastructure. The incident occurred last month and coincided with a series of cyberattacks targeting water infrastructure across 12 states in the US. British officials have not disclosed the name of the affected facility due to security concerns, but confirmed that the outage did not impact the wider electricity supply or national energy generation. The National Cyber Security Centre (NCSC) has been notified, and the UK government has briefed energy sector executives on the incident. This attack reflects a growing trend of Iranian cyber operations against Western targets amid escalating geopolitical tensions. The UK's energy system remains described as highly resilient, with no immediate risk to critical infrastructure reported.

Key Points: • The cyberattack on a UK power plant lasted four days and was linked to Iranian hackers. • The incident is the first successful cyberattack of its kind against UK energy infrastructure. • The UK government has issued guidance to energy companies in response to the attack.
