Cryptocurrency exchange Bithumb announced today (October 29) that the personal information of 6,444 customers was leaked due to an internal system hacking incident.
The company claims that among them, the personal information of 5,600 individuals was leaked in an encrypted state, while the information of the remaining 844 was directly exposed.
Separately, the personal information of 715 executives and employees was also leaked.
Bithumb stated through a notice on its website today that an unauthorized external party infiltrated the internal mobile groupware system 'DowOffice' on October 27, resulting in this scale of personal information leakage.
The hacking incident became known to the public the next day, October 28, and the company later additionally disclosed the scope of the damage, including customer information leaks.
Bithumb explained that out of the 6,444 customers, the information of 5,600 was leaked in the form of encrypted files.
For the other 844 individuals, sensitive information was exposed en masse, including names, mobile phone numbers, email addresses, resident registration numbers, driver's license numbers, as well as account numbers and copies of identification cards.
It was determined that this information was leaked while Bithumb employees were using the internal mobile system during the course of their work.
However, the company stated that the system where this incident occurred is separated from customer exchange accounts and asset holding information, so there were no circumstances indicating that the exchange service or customer database (DB) was directly compromised.
Bithumb urged customers not to comply with requests for verification codes or app installations impersonating employees, and to use the official customer center for damage reports and inquiries.
Bithumb CEO Lee Jae-won said, "We sincerely apologize for causing concern and anxiety to our customers," adding, "If secondary damage is confirmed for customers whose personal information was leaked, we will do our utmost for damage relief and compensation."
He also added, "Taking this incident as an opportunity, we will re-examine the security system of our internal business infrastructure from scratch and make every effort to prevent recurrence."
