Britain and its allies risk losing a conflict in cyberspace against adversaries such as Russia unless citizens, corporations and governments treat cybersecurity with much greater urgency, a UK spy chief is warning.

Anne Keast-Butler, director of the communications intelligence agency GCHQ, will warn Wednesday that Moscow is “relentlessly targeting critical infrastructure, democratic processes, supply chains and public trust” in Britain and Europe. In a speech at a World War II code breaking center near London, she will accuse Russia of stealing technology and plotting sabotage and assassination attempts.

Keast-Butler plans to say that rapid advances in artificial intelligence mean that “the ground beneath our feet is shifting” and there is a “narrowing window for the UK and allies to stay ahead” of countries such as China, a science and technology “superpower.”

She plans to argue there must be an effort “from boardrooms to living rooms” to make cybersecurity “10 times more urgent,” according to extracts released in advance by GCHQ, short for Government Communications Headquarters.
