UK energy companies and other “critical infrastructure” were targeted by hackers believed to have been backed by Russia during last month’s general election, according to Motherboard and The Telegraph. GCHQ’s National Cyber Security Centre recently sent a letter to UK energy companies, manufacturers, and water companies that was leaked to Motherboard, Vice’s technology website.
The letter warns that the spy agency detected “advanced state-sponsored hostile threat actors, who are known to target the energy and manufacturing sectors,” according to Motherboard.
The attack began on June 8, the day of the snap election. The letter does not name the state thought to be behind the attack but the Telegraph reported on Wednesday that it believes Russia to be the country behind the attack.
