Claude’s code: Anthropic leaks source code for AI software engineering tool
Summary
Anthropic accidentally leaked nearly 2,000 internal files and 500,000 lines of code for its Claude Code AI tool due to human error, when an internal file was mistakenly included in a software update and pointed to an archive that was quickly copied to GitHub. The leaked source code spread widely on social media and became GitHub's fastest-ever downloaded repository before Anthropic issued copyright takedown requests to limit its distribution.
Solution / Mitigation
Anthropic issued copyright takedown requests to try to contain the code's spread.
