JPMorgan's Dimon Urges Firms to Harden Cyber Defenses as AI Threats Escalate
JPMorgan Chase CEO Jamie Dimon told business leaders that cyber risk has grown since new AI models emerged, calling it the company's biggest risk "by far." In a WSJ Leadership Institute conversation with Alan Murray, he urged firms to act immediately: segment their networks, tighten identity and access management, and use their strongest AI tools to find weaknesses before attackers do. He also said companies must get better at fixing the flaws they find and should make remediation a standing item in management meetings. Dimon is focused on critical infrastructure and the supplier networks companies rely on. He chairs the Alliance for Critical Infrastructure on an interim basis. The group includes about 50 companies, among them JPMorgan and Mastercard, and he has been recruiting more CEOs to join. He has linked the escalation to Anthropic's Mythos model, saying in an October 6 Bloomberg TV interview that risk rose tenfold after Mythos. Separately, the same day brought news of doubleAI, a Tel Aviv startup backed by Nvidia, which launched Maxwell, a product it describes as a code execution model that runs inside live programs to improve performance. The company says Maxwell cut an early customer's compute costs by 67% and that it plans to charge customers a share of the savings.
