JPMorgan Chase CEO Jamie Dimon said Tuesday that while AI tools could eventually help companies defend against cyberattacks, they are first making them more vulnerable.
Dimon said JPMorgan was testing Anthropic’s latest model — the Mythos preview announced by the AI firm last week — as part of its broader effort to harness the benefits of artificial intelligence while protecting against bad actors using the same technology.
“AI has made it worse and made it more difficult,” Dimon told analysts on the bank’s earnings conference call Tuesday morning. “It creates additional vulnerabilities, and perhaps in the future, better ways to strengthen yourself as well.”
When asked by a reporter about Mythos, Dimon appeared to refer to Anthropic’s warning that the model had already found thousands of vulnerabilities in corporate software.
“I think you’ve read exactly what it is,” Dimon said. “This shows that many more vulnerabilities need to be addressed.”
The comments reveal how artificial intelligence, a technology welcomed by corporations as a productivity enhancer, has also transformed into a serious threat by giving bad actors new ways to hack into technological systems. Last week, Treasury Secretary Scott Bessent called bank CEOs into a meeting to discuss the risks posed by Mythos.
JPMorgan, the world’s largest bank by market capitalization, has for years invested heavily to stay ahead of threats, with dedicated teams and constant coordination with government agencies, Dimon said.
“We spend a lot of money. We have the best experts. We are in constant contact with the government,” he said. “It’s a full-time job and we do it all the time.”
‘Attack mode’
Still, the CEO warned that the risks extend beyond any one institution, given the interconnected nature of the financial system.
“That doesn’t mean that everything banks use is so well protected,” Dimon said. “Banks… are attached to stock markets and all those other things that create other layers of risk.”
Jeremy Barnum, JPMorgan’s chief financial officer, said the industry has long been aware that AI has two effects on cybersecurity.
“These tools can make it easier to find vulnerabilities, but they can also be deployed by bad actors in attack mode,” Barnum said on the results conference call. Recent advances by Anthropic and others have simply intensified an existing trend, he said.
Dimon also said that while advanced AI tools are important, old-school cybersecurity practices remain essential.
“A lot of this is hygiene…how do you protect your data? How do you protect your networks, your routers, your hardware, changing your password?” said. “Doing all those things right dramatically reduces risk.”
Goldman Sachs Chief Executive David Solomon said during an earnings call on Monday that his bank was testing Mythos, although he declined to comment further.
