The largest bitcoin exchange in South Korea and the fourth largest in the world, Bithumb, suffered a hacker attack, as a result of which cybercriminals stole several million dollars from customer accounts, writes TJ .
The exact amount of damage caused by the hackers has not yet been established, but it is known that the attackers gained access to the accounts of 31 thousand Bithumb users, including personal data, phone numbers and email addresses. According to one of the victims, bitcoins worth about 9 thousand US dollars instantly disappeared from his account. About 100 people filed complaints against the exchange with the police.
According to Bithumb representatives, hackers hacked the accounts of 3% of the exchange's clients. They gained access to them by hacking the computer of one of the Bithumb employees, and some data was stolen using one-time passwords that users receive when making transactions. Thus, one of the victims reported that he was contacted by a representative of the exchange, who reported suspicious activity on the account and asked to send an identification number by email, which turned out to be a one-time password for withdrawing funds.
Representatives of the exchange also reported that they had asked the prosecutor's office and the South Korean cybersecurity agency for help in investigating the incident and promised to compensate for losses for some clients.
