Cyber attack shut down small power plant
The government says at no point was there a risk to the UK's energy system during the attack in July.
A minor power plant experienced a four-day shutdown last month due to a cyber attack, according to government sources. While the Department for Energy Security and Net Zero (DESNZ) confirmed that the incident posed no threat to the UK's overall energy system, it has since issued advisories to power companies regarding the risk of such attacks.
The Daily Telegraph identified the perpetrators as hackers with ties to the Iranian regime. Citing security concerns, neither the government nor the National Cyber Security Centre, which handles critical infrastructure attacks, would disclose further details about the affected site. They did, however, clarify that the target was not an essential service like a major power station.
DESNZ reiterated that the incident impacted a small-scale generator and did not jeopardize the broader energy network. The UK's power infrastructure includes several smaller gas generators designed to provide short-term power as needed.
Safeguarding the nation's energy supplies remains a critical government priority. Efforts are underway to update cybersecurity regulations and develop a new energy resilience strategy, expected later this year.
Iran has a recognized capability in cyber warfare. Despite expectations within the Western cybersecurity community of potential attacks from the Iranian state or state-affiliated hackers, particularly in light of its conflict with the US this year, there has been minimal activity to date.
