The cyberattack that raised alert in Britain: "Adapt infrastructure to 21st-century threats"

Hackers linked to Iran's Revolutionary Guards disabled a small "peaker" power plant in Britain for four days. The National Cyber Security Centre and the Energy Ministry briefed energy companies. The British government emphasized that there was no threat to the national power grid.

Hackers linked to Iran's Revolutionary Guards disabled a small "peaker" power plant in Britain for four days. The peaker plant operates during peak hours when localized reinforcements to the power grid are needed. The identity of the facility's owner and its location were not disclosed. Following the incident, the UK's National Cyber Security Centre and the Energy Ministry briefed energy company managers, providing them with instructions on next steps and precautions. The centre operates under the GCHQ intelligence agency. An industry source claimed that due to the small size of the site, it was not subject to a formal cybersecurity framework, and that programmable logic controllers are considered a known vulnerability. The British Energy Association stated that the rise in threat level is concerning and that the incident illustrates the need to adapt infrastructure to 21st-century threats. The government stressed that the energy system is resilient and that at no point was there a threat to the wider system. In March, UK cyber officials warned of potential consequences from activity by Iran-linked hackers. The Telegraph newspaper revealed the details yesterday.
