summary: "UK intelligence chiefs warned the Cabinet that artificial intelligence poses a critical national security threat, with MI5 director Ken McCallum identifying AI as the most pressing issue during a September 8 briefing. The briefing highlighted that hostile nations such as Russia and Iran, along with terrorist groups, may weaponize AI to destabilize the country. A government testing session this summer found 407 vulnerabilities across nine government bodies, including one critical flaw, for £13,000, prompting comparisons to the 2008 financial crash and criticism of senior officials' outdated approach."
