A small power plant in the UK was shut down last month following a cyber attack.
The attack, carried out last month, involved hackers affiliated with the Iranian regime.
The power plant was shut down for four days, the first time an Iranian cyber attack has successfully taken a UK power plant offline.
This incident coincided with a series of attacks on US water infrastructure last month, affecting 12 states.
British and American intelligence agencies have repeatedly raised concerns about hackers from Iran, China, North Korea, and Russia.
Tehran increasingly uses cyber operations and other forms of asymmetric activity in its confrontation with Western states.
Despite the shutdown, the attack did not significantly impact the nation's energy supplies.

The UK has a highly resilient energy system. We work closely with the energy sector to protect infrastructure and ensure the highest security standards.

A government spokesman stated, "The UK has a highly resilient energy system. We work closely with the energy sector to protect infrastructure and ensure the highest security standards."
The spokesman added, "This story refers to an incident impacting a small-scale energy generator, and at no point was there a risk to the wider energy system."
The government claims that at no point was there a risk to the UK's energy system.
The UK's power network includes smaller gas generators for short-term power needs; the incident reportedly affected one such small-scale generator.
The government is updating its cybersecurity regulations and developing a new energy resilience strategy in response to such threats.
Security briefings and updated safety advice were issued to power companies and businesses across the country following the attack.
The UK has allowed the US to launch defensive operations from British bases hosting American planes since the start of its war on Iran but has refused to help in offensive operations.
This policy of not helping in offensive operations has not been altered by the new prime minister, Andy Burnham.
