A security incident at Mixpanel, an analytics provider used by OpenAI, resulted in the exposure of limited data belonging to certain OpenAI API users. The leaked dataset included basic profile information such as names, email addresses, approximate location based on browser data, device details, and user or organization IDs. OpenAI confirmed that none of its own systems were breached and that no sensitive data like passwords, API keys, payment information, chat history, or usage logs was exposed. OpenAI has discontinued using Mixpanel, notified impacted users, and advised increased awareness regarding phishing or social engineering attempts.
