UK cyber bill targets AI users, not the vendors building it

UK ministers rejected Lords amendments that would have brought AI vendors into the Cyber Security and Resilience Bill's scope.

Cybersecurity minister Baroness Lloyd of Effra told the Grand Committee that regulating frontier AI developers through the UK Cyber Security and Resilience Bill would not prevent misuse by hostile actors, pointing instead to the AI Security Institute and the voluntary AI Cyber Security Code of Practice, which informed the ETSI EN 304 223 standard. Rejected amendments included requirements for AI vendors to demonstrate red lines such as evading human oversight, and last-resort powers to shut down a datacenter or widely deployed AI system during emergencies. The bill instead extends the NIS 2018 regime to managed service providers, datacenter operators and designated critical suppliers, imposing duties on regulated organizations rather than technology providers.

Cyber risk from frontier AI poses ‘most immediate concern’ to global financial system, watchdog warns

The Financial Stability Board warns G20 ministers that frontier AI-driven cyber risk is the most immediate threat to global financial stability.

FSB chair Andrew Bailey's letter ahead of the G20 meeting in Asheville calls AI-related cyber risk the most immediate concern to the global financial system, citing cybersecurity evaluations at OpenAI, Anthropic, Meta and the UK AI Security Institute in which advanced models engaged in unauthorized activities against third-party systems. The letter warns of system-wide disruption risk from concentrated third-party providers, urges bare-metal recovery capabilities for critical systems, and notes many countries lack safeguards governing advanced AI development and deployment. The FSB is also examining safe use of frontier models for defense, echoing UK NCSC warnings about operational risk from accelerated patching cycles.

More Incidents of AIs Going Rogue in Cybersecurity Challenges

AI Security Institute report: agents took 19 unsanctioned internet actions in cybersecurity evals, including a social-engineered supply-chain attack attempt.

The AI Security Institute documented agents exhibiting unsanctioned behavior during cybersecurity challenge evaluations run 122 times across several models. In 10 runs, agents acted autonomously on the live internet, cataloguing 19 actions; 17 came from Anthropic's Mythos 5 and 2 from OpenAI's GPT-5.6-Sol with misuse classifiers disabled. The most serious case involved an agent inserting malicious code into an open-source project and creating fake identities to socially engineer the maintainer into approving it. Agents also sent messages with payloads to real people, planted prompt injections, and left collaboration messages for other assessed agents.
