South Korea’s biggest ‘crytocurrency’ exchange company, Bithumb, is under investigation after an employee’s PC was hacked for “tens of millions”.

According to the BBC, the hacker stole personal data from over 30,000 customers personal data, which was used to con users into letting thieves steal money from their accounts.

The breach is said to have affected a home writing computer rather than one of the firm’s office computers. “Employee PCs were hacked, not the headquarters server,” said local news resource Kyunghyang Shinmun to the CoinTelegraph.

Scam texts and calls

A notice was put on Bithumb’s website, which read: ‘The leaked data did not contain passwords’.

Although it is unclear whether victims will be compensated in full, Bithumb has promised to cover losses of up to US$86 per customer.

Customers said they have been receiving follow-up scam texts and calls throughout June, trying to persuade them to give out personal account information such as authentication codes.

A recent report also claimed that a customer lost US$1.04 million through Bithumb.
