MI5 opens AI threat centre AITAC

MI5 Director General Ken McCallum announced a new AI Threat Assessment Centre (AITAC) staffed with experts from the AI Security Institute, NCA and NCSC. He said AI is "supercharging" cyber conflict and that bioweapons misuse is his biggest worry. The same day, a Commons committee questioned OpenAI, Anthropic, Google DeepMind and Meta.

• AITAC is MI5's third centre, after terrorism and state threats
• MI5's state-threat caseload has quadrupled in a decade
• OpenAI admitted more AI-agent incidents exist than disclosed
• Committee chair announced a new inquiry into AI safety
