Unverified claims of ex-DOGE and Cathedral breaches at Anthropic
Overview
Social media posts from Hugging Face CEO Clément Delangue and OpenAI-linked researcher Will Depue claim Anthropic's systems were breached, but neither provides verified evidence.
Delangue cites a Washington Post report that ex-DOGE cyber researchers penetrated Anthropic's systems in under 12 hours using AI agents, reaching Slack channels where sensitive models are discussed. The Washington Post article has not been checked, and Delangue gives no further detail.
Depue says he has heard that Cathedral gained full administrator access to Anthropic's Slack workspace, and that Anthropic is underplaying the incident. He also says China has full access to OpenAI and Anthropic's GitHub, Slack and docs, and argues that the labs' race for speed weakens security. He offers no evidence for these claims. An unsourced Chinese-language post from AI Era (新智元) says Anthropic's internal systems were breached and employee salary data exposed, but its text gives no attack method, data taken, or scope. Anthropic has not responded in these reports.

will depue@willdepueXDepue says AI lab velocity races undermine security against nation-state adversariesAIWill Depue, an OpenAI-linked researcher, argues that CISOs at OpenAI and Anthropic cannot lock down security because leadership prioritizes speed over security in their competition. He says the sprint leaves the results of billions in R&D exposed to national adversaries, calling "security by velocity" workable only for market share, not for the balance of world power. He cites a reported Slack admin-access breach at Anthropic, which he says is underplayed.
will depue@willdepueXWill Depue alleges Anthropic underplays a Slack breach by CathedralAIWill Depue, an OpenAI employee, says he has heard that Cathedral gained full administrator access to Anthropic's Slack workspace, exposing every message and research secret. He says Anthropic and OpenAI keep much of their internal work in Slack, and compares the incident to OpenAI's 2023 breach through an external app's access token. These are unverified claims from a social media post.

He adds that he would not be surprised if Chinese open-source models contain architecture methods stolen from them. He also says a rumor claims Cathedral received a lot of Slack access, possibly all of research.
