Powell and Bessent Meet Top US Banks Over Anthropic Mythos Cyber Threats

The U.S. Government has convened an urgent series of high-level meetings to address the cybersecurity implications of a new artificial intelligence model that has reportedly uncovered vulnerabilities in every major computer operating system. Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell met with the chief executives of the nation’s largest banks this week to discuss the potential for systemic financial instability caused by the release of Anthropic’s Mythos model.

The meetings, which took place on Tuesday in Washington, D.C., were described as a signal that the advanced capabilities of AI are a primary concern for the Trump administration. The gathering occurred while bank heads were already in the capital for a Financial Services Forum board meeting, leading to a special summons at the Treasury Department to discuss the cyber threat of Anthropic’s Mythos model and its potential to threaten the foundation of the U.S. Financial system.

Anthropic, the developer of the Claude chatbot, rolled out Mythos this week in a limited capacity. The company stated that the model’s advanced capabilities are so significant that a wide release would be premature, as it could be exploited by hackers to compromise national security and global economies. To mitigate these risks, Anthropic has launched “Project Glasswing,” a collaborative effort with tech giants including Amazon, Apple, and Nvidia to utilize the model’s capabilities for defensive cybersecurity purposes.

Emergency Summit at the Treasury Department

The closed-door meeting on Tuesday served as a critical briefing for the leaders of the U.S. Banking sector. According to reports from CNBC, the session included the most powerful federal monetary regulators and the heads of several major financial institutions. The urgency of the meeting was underscored by the fact that the CEOs were called to the Treasury Department shortly after a dinner early in the week.

The attendance list for the meeting included Brian Moynihan of Bank of America, Jane Fraser of Citigroup, David Solomon of Goldman Sachs, Ted Pick of Morgan Stanley, and Charlie Scharf of Wells Fargo. Jamie Dimon, CEO of JPMorgan Chase, was invited but was the only major banking CEO unable to attend the session.

A spokesperson for the Treasury Department told CBS News that the agency is actively pushing financial institutions to prepare for these new security threats. The spokesperson further noted that the White House is leading an ongoing core interagency taskforce, which includes the Treasury, to execute a plan ensuring that Americans and the United States are protected from AI-driven vulnerabilities.

Understanding the Mythos Threat and Project Glasswing

The concern surrounding Mythos stems from its ability to identify weaknesses in major operating systems and web browsers. Anthropic has acknowledged that the rate of AI progress means such capabilities will eventually proliferate, potentially reaching actors who are not committed to safe deployment. The company warned that the fallout from such a scenario could be severe for public safety and national security.

In response, Anthropic announced the creation of Project Glasswing. This initiative is described as an “urgent attempt” to pivot these offensive capabilities toward defensive use. By partnering with hardware and software leaders like Nvidia, Apple, and Amazon, Anthropic aims to strengthen the very defenses that Mythos has proven it can breach.

The financial sector is particularly vulnerable to these threats given that of the critical nature of its infrastructure. The ability of an AI model to find zero-day vulnerabilities in operating systems could allow malicious actors to bypass traditional security layers, potentially leading to unauthorized access to financial data or the disruption of payment systems.

Key Takeaways of the AI Security Crisis

  • Government Action: Treasury Secretary Scott Bessent and Fed Chair Jerome Powell summoned top bank CEOs to discuss systemic risks.
  • The Vulnerability: Anthropic’s Mythos model has reportedly found weaknesses in all major computer operating systems and web browsers.
  • Defensive Strategy: Anthropic has launched Project Glasswing with Amazon, Apple, and Nvidia to harden cybersecurity defenses.
  • Limited Release: Due to the severity of the risks, Mythropic is not releasing Mythos to the general public.
  • Interagency Coordination: A White House-led taskforce is coordinating the government’s response to AI security threats.

Systemic Risks to the Financial Foundation

The involvement of the Federal Reserve and the Treasury Department indicates that the government views the Mythos model not merely as a corporate security issue, but as a potential systemic risk. When the most powerful monetary regulators in the U.S. Convene with bank CEOs, it typically suggests a concern that a single point of failure—in this case, a vulnerability in a common operating system—could trigger a wider financial crisis.

The Treasury Department’s push for financial institutions to “prepare for new security threats” suggests that current cybersecurity protocols may be insufficient against the speed and precision of AI-driven attacks. The ability of Mythos to autonomously discover vulnerabilities means that the window for patching software is shrinking, as AI can identify and exploit flaws faster than human teams can typically remediate them.

This development places the U.S. Financial system in a race between “offensive” AI, which can dismantle security, and “defensive” AI, such as the goals set by Project Glasswing. The success of these defensive efforts will be critical in determining whether the financial sector can maintain the trust and stability required for global economic operations.

As the Trump administration continues to engage on AI security, the focus remains on the first phases of a national plan to protect critical infrastructure. The ongoing coordination between the Treasury, the Federal Reserve, and the private sector marks a shift toward a more proactive, albeit urgent, stance on the intersection of generative AI and national cybersecurity.

The Treasury Department and the Federal Reserve have not provided further public comments on the specific details of the Tuesday meeting, citing the confidential nature of the discussions.

The administration’s next steps involve the continued execution of the interagency taskforce’s plan to protect U.S. Infrastructure. Further updates on the progress of Project Glasswing and the implementation of new security mandates for banks are expected as the government continues its engagement with tech and financial leaders.
