Bithumb, a top-five Bitcoin and Ethereum cryptocurrency exchange, announced on Wednesday that hackers have compromised its database.
The thieves stole a database of user information off the personal computer of an employee, rather than off the company's internal network. The attackers allegedly stole the names, email addresses, and mobile phone numbers of more than 31,800 customers, according to a Monday report from Yonhap, a South Korean news wire. No passwords were taken, but “some customers were found to have been stolen from because of the disposable password used in electronic financial transactions."
BraveNewCoin reports that nearly billions of won was stolen (1 bln won = $870,000), but the exact number was not released.
Bithumb said in a notice that it would reimburse victims of the data leak 100,000 won, or about $87, per person. The exchange said it would also compensate people for additional losses related to the attacks. "For those who have suffered additional damage due to this incident, as soon as the amount of damages is confirmed, we will reimburse the entire amount of damages," the company added.
The incident underscores the fact that it is not just investors and digital-currency enthusiasts who are excited by the current surge of interest in cryptocurrencies — criminals are also eyeing up businesses that hold bitcoin and its sister currencies, and no one can promise absolute security. There has been a wild surge of interest in bitcoin, Ethereum, and other digital currencies over the past month, with prices surging to all-time highs. Bitcoin is currently worth about $2,600 per coin, with a total global market cap of $43 billion, while Ethereum trades at about $260 with a market cap of $24 billion.
