An employee at Elon Musk's xAI accidentally leaked an API key on GitHub, which allowed unauthorized access to private large language models (LLMs) used by xAI for internal data from Musk's companies, including SpaceX and Tesla. Despite GitGuardian alerting xAI about the leak nearly two months prior, the key remained active until the repository was removed shortly after direct notification to the security team. Experts warn that the exposure of these internal models poses significant security risks, potentially allowing malicious actors to manipulate sensitive information.
