OpenAI Cuts Mixpanel After Vendor Breach Exposes API User Metadata
OpenAI removed Mixpanel after a smishing attack exposed limited API user data, affecting a small number of customers with no passwords or payment details compromised.
- This past week OpenAI notified some ChatGPT API customers after a breach at its third‑party analytics provider Mixpanel and informed all subscribers despite only API users being affected.
- Mixpanel, the analytics vendor, attributes the access to an SMS‑phishing campaign detected on November 8, linking compromised data to frontend API interactions used by OpenAI.
- Exposed analytics reportedly include names, emails, coarse location and device/browser metadata, while some third parties like CoinTracker reported impact with device metadata and limited transaction counts.
- OpenAI, which removed Mixpanel from production, opened an investigation while notifying organizations, administrators and individual users, as Mixpanel secured accounts, revoked sessions, rotated credentials and blocked attacker IPs.
- With contact data exposed, companies warn users and organizations to expect phishing and verify suspicious messages come from official OpenAI domains; Mixpanel CEO Jen Taylor says all impacted customers have been contacted.
