UK and allies have narrowing window to stay ahead in tech race, spy chief says

Britain Faces Heightened Security Threats Amid Rapid Technological Change

By Michael Holden

LONDON, May 27 (Reuters) - Britain is at a "moment of consequence" amid hybrid attacks from Russia and other adversaries and a narrowing window to stay ahead in the race to develop AI and other technology to protect itself, a British spy chief said on Wednesday.

GCHQ's Warning on Emerging Threats

Delivering the first annual lecture for her GCHQ organisation, Anne Keast-Butler said Britain and businesses needed to take urgent action to address advances from AI and quantum computing to space. The world was in a "new era of radical uncertainty, contested geopolitics and rapidly changing technology," she warned.  

"The risk of miscalculation is as high as I’ve ever seen it," Keast-Butler said.

Role of GCHQ and Intelligence Community

GCHQ, whose role includes eavesdropping on communications and providing national cybersecurity, is one of the three arms of British intelligence, which have for years been warning about the threats posed by Russia and China.

Last month, the head of the National Cyber Security Centre, which is part of GCHQ, warned that Britain should brace for a rise in cyberattacks linked to hostile states.

Efforts to Counter Russian Threats

In her speech at Bletchley Park, the secret home of Britain's codebreakers in World War Two, Keast-Butler said British intelligence and defence partners were "working tirelessly" to degrade the threat from Russia, from cyberattacks, to countering sabotage and assassination attempts.

Support for Ukraine and Intelligence on Casualties

While reiterating Britain's steadfast support for Ukraine, she also said that new intelligence had shown almost half a million Russian soldiers had been killed in Ukraine since the conflict began in 2022.

Neither side publishes casualty figures and both accuse each other of exaggerating their enemy's losses, while assessments by Western intelligence officials and analysts agree that hundreds of thousands of men have been killed and wounded on each side.

Keast-Butler said Moscow was "scaling up its daily hybrid activity against the UK and Europe, stretching from the seabed to cyberspace". 

Protecting Critical Infrastructure

"One area in sharp focus for us is protecting the data and energy flowing through the critical cables and pipelines in and around British waters – we do this by exposing Russia’s intent, motive and underwater capabilities," she said.

Both Moscow and Beijing have routinely denied accusations of cyberattacks or attacks targeting critical infrastructure. There was no immediate response from the Russian embassy in London.

The Unstoppable Force of AI

UNSTOPPABLE FORCE OF AI

With the speed of technological change, such as the advancements in artificial intelligence, she said the "ground beneath our feet is shifting" and Britain and its allies faced a challenge to stay ahead of the competition, not least from China.

Opportunities and Risks of Artificial Intelligence

"AI is an unstoppable force with great opportunity. But it’s also a force with risks," she said. "As AI gains increased autonomy, we all have an intergenerational duty to harness and secure it for good; to protect our national security, our economy and our way of life."

Developing National Cyber Defence Capabilities

She said GCHQ was developing a blueprint for a new national cyber defence capability to speed up its response using agentic AI.

Securing Space-Based Technology

Securing and defending space-based technology was also critical, Keast-Butler said, with both China and Russia investing heavily in space to support both peace and war ambitions. 

"When it comes to technology and data, there’s a narrowing window for the UK and our allies to stay ahead."
