JPMorgan Chase CEO Jamie Dimon says the release of Anthropic’s AI model, Mythos, sharply increases cybersecurity risks for banks. In interviews and conference remarks reported by multiple outlets, Dimon says AI has exposed vulnerabilities that were not previously known and that AI-related threats have risen significantly.

Bloomberg reports Dimon as saying the risk of cyber attacks has increased “10-fold” since Mythos was released. Quartz similarly quotes Dimon describing AI as creating vulnerabilities “we didn’t know about,” while PYMNTS frames the same point around threats rising ten times after Mythos. Business Insider presents the comments as heightened scrutiny on advanced frontier AI models’ safety and cybersecurity implications. Across the coverage, the central difference is emphasis: some outlets focus on the magnitude of the jump in risk, while others highlight the broader safety scrutiny around advanced AI systems.

Dimon also indicates that banks need to address the newly identified vulnerabilities, though the specific technical details and mitigation steps are not described in the cited summaries.
