Some users report a loss of up to 10 million won ($ 8,700) of virtual money. Local newspapers estimated that the hacker had stolen billions of won in virtual currency, but Bithumb did not confirm the exact number of lost money.
According to the article on Monday, the trading floor does not seem to know the exact amount of money lost. However, they said that they would be willing to cover up to a maximum of 100,000 won ($ 897) for each affected user until the end of July 5. 'As soon as we confirm the lost amount, we will compensate the entire damage,' Bithumb said in an official statement.
According to users' complaints, hackers steal both Bitcoin and Ethereum from their accounts. Not only is the fourth largest virtual money trading platform, Bithumb is also the second largest Ethereum transaction on the Internet.
Bithumb told the Korean press that they had contacted police last week and announced the theft. Two months ago, an anonymous attacker also hacked the Bitcoin trading platform Yapizon of Korea and stole 3816.2028 Bitcoin (over $ 5.5 million).
This is not the only Ethereum-related hack in the past week. Last Thursday, an unknown hacker took control of the web domain of Classic Ether Wallet, an e-wallet system for customers of virtual money Ethereum Classic (ETC). Hackers created fake websites and used it to steal user password information and redirect ETC transactions.
