About the breach
The Gemini Data Breach refers to a security incident from late 2022 where a third-party vendor exposed user data from the Gemini cryptocurrency exchange.
What Happened
• Exposed Data: The breach leaked nearly 6 million email addresses and redacted (incomplete) phone numbers of Gemini users, which were later shared and circulated on public hacking forums.
• Security of Funds: Gemini’s core systems, customer accounts, and cryptocurrency funds remained secure; the incident did not involve a direct breach of Gemini's internal servers or user wallets.
Risks and Impacts
• Phishing & Impersonation: Scammers have used the leaked contact information to launch targeted phishing attacks via email, SMS, WhatsApp, and Telegram, often impersonating Gemini support or promising fake airdrops and fund recoveries.
