While Pentagon and Anthropic fight over what is right and wrong, US government is using Claude to ...

The Cybersecurity and Infrastructure Security Agency ( CISA ) is reportedly deploying Anthropic ’s advanced AI model Mythos to scan government software repositories for vulnerabilities, according to a report by Reuters. The audits conducted by CISA’s Attack Surface Evaluation team, aim to recognise bugs that could expose systems to foreign spies or cybercriminals. The report further adds that the scans had already uncovered a large number of vulnerabilities, though details on severity remain undisclosed. The revelation that CISA is actively using Mythos highlights the contradiction in US policy: while the Pentagon and White House spar with Anthropic over safeguards, federal agencies continue to embrace its AI for critical cybersecurity tasks.

Anthropic’s rocky ties with the government
The move comes as Anthropic navigates a tense relationship with the US government . Earlier this year, the Pentagon attempted to blacklist the company with a “supply-chain risk” designation after Anthropic refused to remove safeguards preventing its AI from being used for autonomous weapons or domestic surveillance. A judge later blocked the designation, easing tensions. Despite the standoff, US agencies have continued to adopt Anthropic’s tools. The NSA has been testing Mythos since April, with analysts reportedly impressed by its cybersecurity capabilities.

White House clash over public release
When Anthropic rolled out a public version of Mythos called Fable, the White House demanded that foreign users be banned, triggering a temporary global shutdown of the model. Access was restored only last week, underscoring the administration’s unease over the potential misuse of frontier AI systems.
