A recent data security incident involving OpenAI’s analytics provider, Mixpanel, has led to the exposure of limited customer information for some ChatGPT API users. This event did not involve a breach of OpenAI’s own infrastructure, and no sensitive data such as chat histories, passwords, API keys, or payment details were accessed. The situation highlights the risks associated with third-party service dependencies in modern software ecosystems.
Mixpanel, which supplies event analytics to monitor user interactions on OpenAI’s API frontend, experienced a security compromise traced to a smishing, or SMS phishing, attack. OpenAI clarified that only a subset of API customers were affected, while users of ChatGPT and other company products remained untouched. The analytics firm detected the intrusion on November 8, and OpenAI received specifics about the exposed dataset on November 25.
Information potentially accessed includes names tied to API accounts, associated email addresses, approximate geographic location data, operating system and browser details, referring websites, and organization or user IDs. Because credentials and sensitive usage data were not compromised, OpenAI has stated that affected individuals do not need to reset passwords or generate new API keys.
In response, OpenAI has initiated its own investigation, removed Mixpanel from production systems, and begun notifying administrators, organizations, and individual users. Although only API users were impacted, the company has proactively informed all subscribers out of caution.
OpenAI is urging users to remain vigilant against phishing or social-engineering attempts that may leverage the leaked information. Recipients of messages referencing the incident should verify that any links or attachments originate from official OpenAI domains. The company also recommends enabling two-factor authentication and never transmitting sensitive data, including passwords, API keys, or verification codes, via email, text, or chat.
Separately, cryptocurrency platform CoinTracker has also reported exposure through the same incident, with affected data including device metadata and limited transaction counts.
Mixpanel’s CEO, Jen Taylor, confirmed that all impacted customers have been contacted directly. The company has taken steps to secure affected accounts, revoke active sessions, rotate credentials, block threat actor IP addresses, and reset employee passwords. Additional security controls have been implemented to guard against similar incidents going forward.
