The highly confidential internal design of the Amazon-backed tech was published due to “human error”.
AI giant Anthropic has mistakenly published its own top secret internal code, triggering a viral wave of github rewrites and inflicting potentially catastrophic commercial damage on the Amazon-backed business model.
The developer of the Claude chatbot described the incident as a release issue “caused by human error, not a security breach,” according to US technology news website VentureBeat on Tuesday.
Anthropic was designated a “risk to national security” by US Defense Secretary Pete Hegseth in February after disagreements with the Pentagon over the use of its artificial intelligence systems.
The leak involved more than 500,000 lines of code linked to Claude Code, Anthropic’s AI coding assistant, which helps users write and manage software through natural language commands, according to Axios and The Verge. The material included unreleased features, performance data, and developer notes.
The code spread rapidly online, with versions of the code being placed on code-sharing platform GitHub and replicated thousands of times within hours, according to Ars Technica and The Verge. Anthropic moved to remove the material and issued takedown notices, but the material had already been widely copied and circulated, the reports said.
According to VentureBeat, by exposing the “blueprints” of Claude Code, the leak may have given “bad actors” a “road map” to bypassing security checks or tricking the tool into running hidden commands or accessing data without the user’s knowledge.
A separate data leak reported in February exposed internal materials revealing details of Anthropic’s unreleased model, known as Claude Mythos, after thousands of draft documents were left accessible in a public data cache.
The model was described in the leaked material as the company’s most powerful system to date which could pose “unprecedented cybersecurity risks” if deployed widely. The company has withheld its release due to concerns over its capabilities and potential misuse, according to US business magazine Fortune.
