Mixpanel–OpenAI security incident (2025)

In November 2025, OpenAI disclosed that its third-party analytics provider Mixpanel had experienced a security incident involving unauthorized access to part of Mixpanel’s systems. [11] According to OpenAI, an attacker exported a dataset containing limited customer-identifiable analytics information for some users of OpenAI’s API platform. Exposed data included names and email addresses associated with API accounts, coarse location metadata, browser and operating-system details, referring websites, and organization or user IDs. No chat data, API request content, logs, passwords, API keys, payment information, or other sensitive data were affected.

OpenAI removed Mixpanel from its production environment, began notifying impacted users, and initiated a broader review of external vendors. Mixpanel stated that the incident resulted from a targeted SMS-based social-engineering attack and said it had revoked sessions, rotated credentials, blocked malicious IPs, and engaged external cybersecurity investigators. OpenAI advised affected users to remain vigilant against phishing or social-engineering attempts.
