Story summary

On October 13, 2026, Sir Ken McCallum, the director general of MI5, warned during his annual speech at Thames House that terrorists could exploit artificial intelligence (AI) to develop biological weapons or create new pathogens, posing a significant threat to Britain. This warning came as part of a broader assessment where he highlighted increased state threats from countries like Iran and Russia, noting that these threats have quadrupled over the past decade, requiring MI5 to allocate more resources than during the Cold War.

McCallum also mentioned specific incidents such as Iran's suspected plot against RAF Fairford in Gloucestershire and Russia’s use of hybrid warfare tactics below the threshold for direct NATO response. He emphasized the potential misuse of AI by terrorists, including its application in reconnaissance and attack methodologies with AI-enabled drones adding a new dimension to threats.

The speech underscored that while biological weapon capabilities have not yet been realized through AI, the risk remains high if guardrails against such misuse fail. This has prompted MI5 to establish the AI Threat Assessment Centre (AITAC) to manage these risks proactively.
