MI5 Expands Resources Against State Threats
Tap title to read story
MI5 chief Sir Ken McCallum announced that the service is devoting more resources to countering state threats than during the Cold War, noting a quadruple rise in foreign adversary activity over the last decade.
He warned that Russia, Iran and emerging AI technologies pose equal operational scale threats, with Russia engaging in hybrid warfare and Iran targeting Jewish communities and military sites. The National Security Act of two thousand and twenty‑three is now heavily used to tackle threats from China, Iran and Russia, while AI‑enabled drones and potential bioweapons remain a growing concern.
McCallum highlighted that MI5 has expelled nearly one thousand Russian spies since the Ukraine invasion, weakening the Kremlin’s covert operations. He urged the UK to stay ahead of AI‑driven propaganda and radicalisation, stressing that extremist groups could soon harness AI to develop bioweapons, a threat he described as not yet realised but imminent.
