Federal Chief Information Officer Greg Barbaccia said Tuesday the government is approaching Anthropic’s Mythos model with measured expectations, acknowledging both its potential to strengthen federal cyber defenses and the significant uncertainties that remain about how it would perform in real-world conditions.

Barbaccia said his direct exposure to Mythos has been limited to evaluations and benchmarking tests, and that no federal agencies have deployed it yet. While he says the Office of the National Cyber Director is coordinating the government’s approach, his broader assessment of where AI-assisted cybersecurity is heading was direct.

“We’re going to get to a world soon where AI defense will be able to catch up,” Barbaccia told CyberScoop on Tuesday at the Workday Federal Forum, produced by Scoop News Group. “We must get to a point where the bots are finding the bots.”

Earlier this month, Barbaccia sent an email to cabinet agencies to inform them that the Office of Management and Budget has started laying the groundwork for a controlled rollout of the model to federal agencies.

His framing reflects a view that the same capabilities making Mythos a potential offensive threat are precisely what make it valuable as a defensive tool. Anthropic has said the model identified thousands of previously unknown, high-severity vulnerabilities across major operating systems and web browsers during testing, many of them decades old. The question for federal security teams is not whether those capabilities are real, but whether they translate from controlled laboratory settings to the complex, defended networks that government agencies actually run.

Barbaccia was candid about that gap.

“I think it’ll uplevel people and make a novice cybersecurity offensive operator more efficient,” he told CyberScoop. “But the jury is still out on how effective it’ll be against real-world conditions, meaning a network that’s guarded by…
