GCHQ warns Russia is intensifying hybrid attacks against the UK and Europe

Russia is “relentlessly” targeting critical infrastructure, democratic processes, supply chains, and public trust in the UK and Europe, the head of GCHQ will warn.

Anne Keast-Butler is set to give the inaugural GCHQ annual lecture on Wednesday, detailing how Russia is increasing its daily hybrid activity against countries including Britain and urging the public and businesses to make cyber security “10 times more urgent.”

She is expected to highlight the organisation’s efforts in “disrupting Russia’s attempts to smuggle western tech, fending off cyber attacks, and countering reckless sabotage and assassination attempts,” adding, “as we remain steadfast in our support for Ukraine, Putin is going backwards on the battlefield.”

Russia is “relentlessly targeting critical infrastructure, democratic processes, supply chains, and public trust,” she is expected to tell the audience, and the speed of advancements in technology means there is a “narrowing window for the UK and allies to stay ahead,” she will say.

“China is now a science and tech superpower, with sophisticated capabilities across their intelligence, cyber, and military agencies,” and rapid progression in AI means “the ground beneath our feet is shifting,” the audience will hear.

She will urge the technology industry and those working in national security to “anticipate and drive advancements, together, at the speed of the frontier,” as well as calling on the public to take action “from boardrooms to living rooms” to increase cyber security.

“At home, that means taking important action now to switch passwords for passkeys, and for wider society, it means hardwiring security into new technologies, protecting supply chains, and making cyber security 10 times more urgent,” she will say.

Earlier this year, Dr. Richard Horne, head of the National Cyber Security Centre which is part of GCHQ, warned that most nationally significant cyber attacks on Britain were carried out by hostile states including China, Iran, and Russia.

He said the body dealt with around four of these attacks each week and warned businesses to be prepared to protect themselves against cyber attacks without needing the option of paying ransoms, because the UK could be targeted “at scale” if it were to become involved in an international conflict.
