UK not heeding warning over China threat, says ex-cybersecurity chief

Ciaran Martin says US warning that China is targeting key infrastructure should be taken more seriously

The UK is not paying enough attention to a gamechanging" shift in China's cyber-espionage tactics towards infiltrating critical infrastructure including energy and communications networks, a former head of Britain's cybersecurity agency has warned.

Ciaran Martin, the ex-chief executive of the National Cyber Security Centre, said a warning from the US this year that Chinese state-backed hackers were targeting key sectors was a pivotal moment in Beijing's approach to cyberwarfare.
