Banks Face Complex Cyber Risks From Anthropic’s Mythos

Anthropic’s new artificial intelligence (AI) model Mythos poses a significant threat to the banking industry, as it could expose legacy systems to “unprecedented cyber risks,” Reuters reported Monday (April 13).

Experts interviewed by Reuters said Mythos could power complex cyberattacks as it can identify cyber vulnerabilities as well as ways to exploit them, according to the report.

Banks and other financial institutions are threatened by these sorts of attacks because they run technology stacks that include both new and decades-old technologies, house undiscovered vulnerabilities, and are closely connected, experts said, per the report.

It was reported Tuesday (April 7) that Anthropic unveiled a program called Project Glasswing that will allow select partners to gain early access to “Claude Mythos Preview” to allow these partners to identify vulnerabilities and strengthen systems before threats can be exploited.

The initiative includes participation from leading companies such as Amazon, Microsoft and Apple, alongside cybersecurity and infrastructure players like CrowdStrike, Palo Alto Networks, Google and Nvidia.

In its announcement of Project Glasswing, Anthropic said: “We are hopeful that Project Glasswing can seed a larger effort across industry and the private sector, with all parties helping to address the biggest questions around the impact of powerful models on security.”

In November, Anthropic reported that another of its AI models had been manipulated into carrying out a wide-reaching cyber-espionage operation.

It was reported Thursday (April 9) that the heads of the Treasury Department and the Federal Reserve held an “urgent” meeting with CEOs of major banks to discuss concerns about potential future cyber risks posed by Mythos and other AI models.

Reached by PYMNTS, a Treasury spokesperson said Friday (April 10) that Treasury Secretary Scott Bessent convened a meeting with bank CEOs to address developments in AI and that Treasury plans to lead more such meetings with regulators and institutions on an ongoing basis.

It was also reported Friday that America’s biggest banks are beginning in-house tests of Mythos and that the White House is encouraging banks to use Mythos to identify vulnerabilities. The report said JPMorganChase, Goldman Sachs, Citigroup, Bank of America and Morgan Stanley are among the banks testing the tool internally.
