Bank of America hires 1,000 staff to defend systems against rogue AI agents

The story first became public on October 14. According to The Next Web, Bank of America CEO Brian Moynihan said in a CNBC interview that day — which took place after the bank reported its third-quarter results — that the bank had brought in about 1,000 outside contractors in the second quarter to repair software weaknesses exposed by AI models. He singled out one of those models by name: Anthropic's Mythos.

The next day, October 15, Business Insider reported a different framing of the same disclosure. In its account, Moynihan told analysts that BofA had hired 1,000 extra staff for what he called "Mythos remediation," work aimed at protecting the bank's software from damage by rogue AI agents. Business Insider described it as the first time a major bank has disclosed a large-scale defensive hiring effort against malicious or runaway AI agents.

The two reports agree on the headline figure of roughly 1,000 people and both tie the effort to the name Mythos, but they part ways on the details. The Next Web describes outside contractors brought on in the second quarter to fix weaknesses that AI models surfaced in the bank's code; Business Insider describes additional employees hired to guard critical systems against destructive AI agents. Neither report explains how the two accounts fit together, and Business Insider does not explicitly connect the "Mythos" in "Mythos remediation" to the Anthropic model. As of October 15, there has been no further development or clarification from the bank.
