  • Anthropic mistakenly released the entire code for its AI model, Claude Code, and part of its software source map online, which could be used to reconstruct the proprietary source code.
  • The release was attributed to a human error, not a security breach and no sensitive data or login credentials were leaked.
  • The exposed code dates from version 2.1.88 of the software, released on March 31st.
  • This incident followed a previous leak that revealed Anthropic is working on an even more powerful AI model named Mythos, which also raised cybersecurity concerns.
  • Despite the accidental leak, the exposed code could potentially allow competitors to learn about the model’s work and architecture, leveraging this knowledge to craft rival versions.
  • Anthropic’s spokesperson at first claimed the leaked code was legitimate because it was open source, but later clarified that this was incorrect and it was actually proprietary code.
  • The files that were leaked were promptly removed from online platforms. Sole24Ore retrieved those files and analyzed them using Anthropic’s own newest model.
  • Despite Anthropic’s reassurance that the data didn’t contain sensitive details, it raised the question of the possible exposure of confidential project Mythos.
