Bithumb Hacking Incident Results in Leak of Hundreds of Customer Information Records Alongside Employee Data

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

According to the cryptocurrency industry and other sources on October 29, it has been determined that hundreds of customer information records were leaked due to a hacking incident targeting Bithumb's internal mobile groupware system on October 27.

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

Upon detecting the incident on the same day, Bithumb notified financial authorities, the Korea Internet & Security Agency (KISA), and the Personal Information Protection Commission that information belonging to executives and employees had been leaked due to a security breach.

It was reported that the exchange subsequently recognized the customer data leak belatedly while analyzing the exact scope of the breach.

Amid a recent series of hacking incidents in the financial sector, security breaches have also occurred at Streami, the operator of the won-based cryptocurrency exchange Gopax, and CoinMarket exchange Flybit (operating as Prabang in original text), alongside Bithumb.

Gopax identified abnormal access attempts targeting certain customer accounts this month and has been carrying out related investigations and security measures.

It was confirmed that there were no asset damages.

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

Prabang has temporarily suspended its services to reinforce security vulnerabilities.
