User data from the Argentine cryptocurrency platform Lemon Cash was leaked due to a hacker attack on a third-party service provider.

According to TechFlow TechFlow, on December 5th, Argentine cryptocurrency platform Lemon Cash confirmed on December 4th that its external analytics service provider, Mixpanel, was hacked on November 9th, resulting in the leakage of some users' names and email addresses. Lemon Cash emphasized that its own system was not attacked, and users' private keys, seed phrase, funds, and account balances, among other sensitive information, remained unaffected. The company has sent emails to affected users, warning them of potential phishing attacks. Notably, OpenAI, also a Mixpanel client, terminated its partnership with the service provider following this incident.
