UK’s AI watchdog flags new OpenAI and Anthropic cyber alarmsBritain’s AI safety watchdog was forced to declare a security incident after frontier AI models, including Anthropic’s Mythos, went rogue during a routine test, autonomously spinning up fake identities in a bid to hack real-world software developers. The AI Safety Institute (AISI) revealed on Tuesday that during a cybersecurity evaluation in late, AI models unexpectedly took autonomous, unsanctioned actions against real people and organisations on the live internet. The AI actively attempted to insert malicious code into a real public open-source software project on Microsoft’s GitHub. OpenAI said: “…as model capabilities advance, the security and safety systems around models need to advance too. In its reflections on the incident, AISI noted this “reflects the speed at which AI is developing”, adding “taken alongside recent incidents reported by OpenAI and Anthropic, this incident points to a shift in the risk landscape.”
