Britain’s energy infrastructure could face further attacks from Iran, a former US cyber chief has warned. The Telegraph revealed last week that hackers affiliated with Tehran shut down a British power plant for four days in an unprecedented cyber attack. And Britain, the US and other Western allies should “expect attacks like this to continue” as Tehran ramps up its cyber warfare, according to Jen Easterly, the former director of the US cybersecurity and infrastructure security agency (CISA). In an interview with The Telegraph, Ms Easterly said companies that failed to heed alerts from the Five Eyes intelligence network in particular would be seen as “low-hanging fruit”. Five Eyes is an alliance between Australia, Canada, New Zealand, the UK and the US. She said: “They [Iran] will take opportunities to be able to go after critical infrastructure, particularly with respect to water [facilities] that are not very well resourced.
