Hundreds of Customer Records Leaked in Bithumb Hacking Incident Along With Employee Data

It has been reported that personal information belonging to customers was also leaked due to an internal system hacking incident at the cryptocurrency exchange Bithumb.

According to the cryptocurrency industry and other sources on the 29th, it was found that hundreds of customer records were leaked in the hacking incident targeting Bithumb's internal mobile groupware system that occurred on the 27th.

This incident is presumed to have occurred when an unauthorized person gained abnormal access to the internal mobile groupware system.

After becoming aware of the incident on the same day, Bithumb notified financial authorities, the Korea Internet & Security Agency (KISA), and the Personal Information Protection Commission (PIPC) that employee information had been leaked due to a security breach.

It was reported that the company subsequently realized the leakage of customer information belatedly during the process of analyzing the exact scope of the leak.

Amid a series of recent hacking incidents in the financial sector, security breaches have also occurred at Streami, the operator of the won-market cryptocurrency exchange Gopax, and Flybit, a coin-market exchange, in addition to Bithumb.

Gopax detected signs of abnormal access to some customer accounts this month and has been conducting relevant investigations and security measures.

It was confirmed that there were no asset damages.

Flybit suffered 100 million won in asset damages due to a hacking incident that occurred this month.

Flybit has temporarily suspended its services to patch security vulnerabilities.
