Encrypted lending service Celsius has discovered a data breach in one of its third-party service providers, which has exposed the personal information of its customers. According to the email, the hacker gained access to the "third-party email distribution system" used by Celsius. Hackers use this information to send fraudulent emails and text messages to trick them into revealing the private keys of their funds. On April 14, Celsius users started reporting a fraudulent website claiming to be the official Celsius platform. Some users also receive text messages and emails claiming to be Celsius official, can link to the website, and prompt the recipient to enter sensitive information. It is reported that Celsius' competitor BlockFi suffered a similar data breach last spring.
