Iranian hackers carry out unprecedented attack on UK's power network

Iranian-affiliated hackers reportedly shut down a small-scale power generator in the UK for four days in a cyber attack last month, marking what The Telegraph calls an unprecedented success against a UK energy facility of that type. The report says the incident did not threaten the wider grid. It was believed to have been reported to the National Cyber Security Centre (NCSC), part of GCHQ, and the government issued briefings to power companies and guidance to businesses. Earlier, NCSC head Dr Richard Horne warned that most major cyber attacks on Britain are carried out by hostile states including China, Iran and Russia, and cautioned companies to prepare without relying on ransom options. GCHQ has also developed plans for a national AI “cyber shield” intended to help protect critical infrastructure.
