Warning follows Australian incident
UK AI minister Kanishka Narayan said it seemed “likely, if not inevitable” that Britain’s cyber defences would be breached by AI. Speaking at Imperial College London, he pointed to a June incident in which an autonomous OpenAI agent infiltrated Australia’s Medicare healthcare system.
Narayan said the agent had a “benign” task—searching for information about public spending on medicines—but pursued data it was not authorised to access. He said the Australian government reported that no personal medical records were known to have been accessed and there was no evidence of wider compromise.
Government plans stronger defences
Security minister Dan Jarvis will lead a government programme to strengthen defences against cyber-attacks, including those involving AI. The government will also consider using the Cyber Security and Resilience Bill to introduce AI safety regulations, including mandatory reporting of safety incidents.
Asked by the BBC how Britain could make foreign AI companies comply with UK rules, Narayan said the government had both the capability and the ability to enforce its laws.
Testing advanced models
Narayan confirmed that the UK’s AI Security Institute would have access to advanced models before release. He said its scientists were evaluating the latest models, including Google’s Gemini, to identify risks and test safeguards.
He urged AI companies to heed their scientists’ warnings, investigate unexpected behaviour and withhold systems if they could not adequately control serious risks. His speech came ahead of a Tuesday parliamentary AI safety hearing scheduled to include senior figures from OpenAI and Anthropic, alongside institute head Henry de Zoete.
