Bithumb’s Response

This is what Bithumb has said regarding the hack:

The employee PC, not the head office server, was hacked. Personal information such as mobile phone and email address of some users were leaked. However, some customers were found to have been stolen from because of the disposable password used in electronic financial transactions.

The information stolen in the hack may lead to vishing attempts where scammers call victims on their phones and pose as Bithumb representatives, which may lead to further damage.

Bithumb has published an official statement saying that “compensation for personal information leakage cases has been decided,” and they would pay up to 100,000 won per person.

It is also not known yet whether the exchange will be held legally responsible for the lost funds. As pointed out by experts, this situation is quite complicated due to lack of regulation in terms of digital currencies in South Korea.
