Iran-linked hackers target UK power plant and US water infrastructure

Security Affairs reports that Iran-linked hackers successfully shut down a British power plant for four days, marking the first confirmed cyberattack of its kind against UK energy infrastructure. This incident occurred concurrently with a series of attacks targeting water infrastructure across 12 US states.

The UK power plant, which was not named due to security concerns, was offline for four days before being restored by staff. Although the plant was small and did not impact the wider UK power supply, the incident prompted warnings to power companies and businesses. The attack was reported to the National Cyber Security Centre.

In the US, dozens of wastewater treatment plants in 12 states were affected, leading to flooding and loss of water pressure. The FBI attributed these incidents to malicious cyber actors, with US government sources confirming the threat likely originated in Iran. The UK attack's intent is believed to be a demonstration of capability rather than direct harm. Iran has increased cyberattacks on Western countries since February, with operations reported in several European nations. Experts have warned of the UK's unpreparedness for such threats, and AI is noted as a factor lowering the barrier for cyberattacks.
