Cryptocurrency exchange Gemini appears to have suffered a data breach on or before Dec. 13. According to documents obtained by Cointelegraph, hackers gained access to 5,701,649 lines of information pertaining to customers’ account numbers, email addresses and partial phone numbers. In the case of the latter, hackers apparently did not gain access to the full phone numbers, as certain numeric digits were obfuscated.
The leaked database did not include sensitive personal information such as names, addresses and other Know Your Customer information. In addition, some emails were repeated in the document; thus, the number of customers affected is likely lower than the total rows of information. Gemini currently has 13 million active users.
