Blindsided by AI Agents, Big Banks Scramble to Beef Up Security

Major U.S. banks including Morgan Stanley, Bank of America, and Wells Fargo are rapidly updating policies to restrict autonomous AI agents like Meta's Muse from accessing customer accounts due to security concerns. Muse has surged in popularity, reaching over 10 million U.S. downloads in 40 days, prompting banks to limit AI agent access amid risks of unpredictable behavior. Other AI developers like OpenAI and Anthropic have also launched similar agents, intensifying the challenge for financials.
