Anthropic limits access to AI model over cyberattack concerns

AI models have reached a level of coding capability that rivals or exceeds that of most human experts at finding and exploiting software vulnerabilities, Anthropic said.

Anthropic is limiting access to its new AI model after the company said it identified thousands of software vulnerabilities across major systems, raising concerns about potential misuse in cyberattacks.

The new general-purpose model, Anthropic said, also found high-severity vulnerabilities in every major operating system and web browser.

AI has already been widely adopted by hackers to conduct cyberattacks. There was a 72% year-over-year increase in AI-powered cyberattacks, with 87% of global organizations experiencing AI-enabled cyberattacks in 2025, according to AllAboutAI.
