Mixpanel data breach, and thanks for honesty OpenAI

AI OpenAI Security

Attacker gained unauthorised access to Mixpanel platform and OpenAI user data was collected (names, emails, location and organisation info, etc.).

I am not using Mixpanel myself and I can not say how soon were their customers notified of this incident, but based on public info it happened almost 20 days ago.

This stolen info can now be used as part of ‘phishing or social engineering attacks’, so be vigilant.
