OpenAI has disclosed a security breach affecting its API customers due to a hack on its third-party analytics provider, Mixpanel. In this article, we will delve into the details of the incident, the implications for users, and what measures OpenAI is taking to rectify the situation.
On November 27, 2025, OpenAI notified some ChatGPT API customers that limited identifying information was exposed following a breach at its third-party analytics provider, Mixpanel. The breach occurred when Mixpanel's CEO, Jen Taylor, revealed in a statement that an attack on their system had compromised data related to "limited analytics data" from users of the API.
According to OpenAI, the cyber incident did not impact users of ChatGPT or other products and did not involve the exposure of sensitive credentials such as chat requests, API usage data, passwords, credentials, API keys, payment details, or government IDs. However, it is worth noting that some users have reported that another cryptocurrency portfolio tracker and tax platform, CoinTracker, has also been impacted by the breach.
Mixpanel's statement also revealed that the attack resulted from a smishing (SMS phishing) campaign that the company detected on November 8. The incident was first reported to OpenAI after November 25, when Mixpanel informed them of the affected dataset.
OpenAI received details of the exposed data and has warned its users about the potential for phishing or social-engineering attacks related to the incident. In an effort to prevent further exploitation, OpenAI has started removing Mixpanel from its production services and is notifying all its subscribers directly.
The implications of this breach are significant, particularly for API customers who use Mixpanel's analytics tools. While no sensitive information was exposed, data breaches can have far-reaching consequences, including identity theft, financial losses, and reputational damage.
In light of the incident, it has never been more important for organizations to prioritize security measures such as two-factor authentication (2FA) and to take steps to prevent phishing attacks. OpenAI is taking proactive measures by removing Mixpanel from its production services and notifying affected customers directly.
Furthermore, this incident highlights the importance of maintaining robust vendor relationships and due diligence when selecting third-party providers. Organizations must ensure that their vendors have adequate security measures in place to protect sensitive data and that they are able to detect and respond quickly to security incidents.
In conclusion, the breach at Mixpanel has significant implications for OpenAI API customers and organizations that rely on analytics tools. While OpenAI's response has been swift and proactive, it serves as a cautionary tale of the importance of prioritizing security measures and due diligence when selecting third-party vendors.
