Suspected Iran-linked attack knocked UK power plant offline for days

Suspected Iranian hackers knocked a small UK power plant offline for four days in July 2026, with no noticeable impact on the national grid.

Sources told The Telegraph that a British power plant was offline for four days in July 2026 following a suspected Iranian cyberattack, reported to the National Cyber Security Centre. The UK energy minister said the incident affected a small-scale energy generator with no noticeable effect on the power supply, and energy CEOs were briefed and given further advice afterward. The attack followed warnings about Iranian cyber activity against US energy, water, and government networks, including a coordinated attack on 30+ US community water utilities.

UK and allies expose spyware used by Iranian state actors to target dissidents, activists and journalists

Joint advisory details Iranian spear-phishing campaign deploying CHOSEN BRICK spyware to surveil dissidents, activists, and journalists across UK, US, Netherlands.

The NCSC (part of GCHQ), FBI, and AIVD jointly warned that Iranian state actors impersonate trusted contacts on WhatsApp and Telegram to deploy the CHOSEN BRICK spyware against dissidents, activists, and journalists worldwide. The Windows-only malware is persistent across reboots and collects contacts, emails, social media messages, screen captures, and microphone audio. Stolen personal details of some victims have been published on pro-Iranian leak sites. The FBI published complementary technical analysis, and the NCSC offers free cyber defence services for high-risk individuals.
