JPMorgan Chase & Co. CEO Jamie Dimon said Tuesday that while artificial intelligence tools may ultimately help protect companies from cyberattacks, they first make them more vulnerable.
Dimon said JPMorgan is testing Anthropic’s latest model, the Mythos preview the AI company announced last week, as part of a broader effort to reap the benefits of AI while protecting against attackers who exploit the same technology.
“AI has made things worse and more difficult,” Dimon told analysts during the bank’s earnings call Tuesday morning. “It creates further vulnerabilities, but perhaps also creates better ways to strengthen ourselves in the future.”
When asked about Mythos by a reporter, Dimon seemed to be referring to Anthropic’s warning that the model has already discovered thousands of vulnerabilities in corporate software.
“I think I read exactly what it was,” Dimon said. “This shows that even more vulnerabilities need to be fixed.”
The remarks reveal how artificial intelligence, a technology hailed by businesses as a productivity boon, is also morphing into a serious threat by giving bad actors new ways to hack technology systems. Last week, Treasury Secretary Scott Bessent called bank CEOs to a meeting to discuss the risks posed by Mythos.
JPMorgan, the world’s largest bank by market capitalization, has invested heavily over the years to stay ahead of threats with a dedicated team and constant collaboration with government agencies, Dimon said.
“We are spending a lot of money. We have top experts. We are in constant contact with the government,” he said. “This is a full-time job and we do it all the time.”
“Attack mode”
Still, the CEO warned that given the interconnected nature of the financial system, risks extend beyond a single institution.
“That doesn’t mean everything that banks rely on is that well protected,” Dimon said. “Banks…are tied to exchanges and everything else that creates risk.”
JPMorgan Chief Financial Officer Jeremy Burnham said the industry has long known that AI works both ways in cybersecurity.
“While these tools make it easier to discover vulnerabilities, they can also be deployed by malicious parties in attack mode,” Burnham said on the earnings call. Recent advances by Anthropic and others have simply reinforced existing trends, he said.
Dimon also said that while advanced AI tools are important, old-fashioned cybersecurity practices remain essential.
“A lot of it is hygiene… How do you protect your data? How do you protect your network, routers, hardware, change passcodes?” he said. “If you do all of this correctly, the risk is dramatically reduced.”
Goldman Sachs CEO David Solomon said on an earnings call Monday that his bank was testing Mythos, but declined to comment further.
