Anthropic's closed-source coding product Claude Code experienced a significant source leak exposing over 500k lines of orchestration logic, including autonomous modes and memory systems, but not model weights. The leak led to rapid public reverse-engineering, numerous forks with up to 32.6k stars and 44.3k forks, and subsequent DMCA takedowns by Anthropic. Suspicious npm packages emerged targeting users compiling the leaked code, creating a live security hazard. Discussions also mention unreleased model references like "mythos" and ongoing product feature updates despite the leak. "OFFICIAL STATEMENT from Anthropic regarding the leak" was noted but not detailed.
