Anthropic

said

late last year that state-sponsored Chinese hackers used its artificial intelligence technology in an effort to infiltrate the computer systems of roughly 30 companies and government agencies around the world.

In a

blog post

, Anthropic said it was the first reported case of a cyberattack in which A.I. technologies had gathered sensitive information with limited help from human operators. Human hackers, the company said, handled about 10 to 20 percent of the work needed to conduct the attack.

Five months later, that remains the only known example of a cyberattack driven largely by an “A.I. agent” —

technology that can write computer code and use software on its own

. But as Anthropic and its chief rival, OpenAI, prepare to release new and more powerful A.I. systems, cybersecurity experts have become increasingly vocal in their warnings that A.I. is fundamentally changing cybersecurity.

Technology from Anthropic, OpenAI, Google and other companies could allow hackers to identify security holes in computer systems far faster than in the past, vastly raising the stakes in the decades-long fight between hackers and the security experts guarding computer networks.

But like other tools from the long history of cybersecurity, the latest A.I. can be used for both offense and defense. As hackers deploy A.I. to break and steal, security experts are also leaning on A.I. to spot flaws in their systems — including some that had gone unnoticed for decades. The question is who finds the flaws first.

“This is the most change in the cyber environment, ever,” said Francis deSouza, the chief operating officer and president of security products at Google Cloud. “You have to fight A.I. with A.I.”
