In order to enact the attack, the cybercriminal uses the data leak that occurred on JUL 07, 2017, impersonated a Bithumb Customer Center agent, and contacted some people who provided them with data that they believed the Bithumb employee was the only one who would get it.
The hacker then sent a message to the victims stating that he discovered a suspicious login attempt on them accounts and that he needed a verification code.
Once he got the code, he withdrew them balance.
Victims attempted to get $ 126,000 and $ 38,000, respectively, for damages related to the data breach in 2017.
According to Fn News, plaintiffs Hong and Seo (both named only by their surname) stated that they had lost money due to a phishing attack using private data that was extracted in a hack of Bithumb. The third claimant, Jang, was granted $5,000 to cover his total loss. This amount reflects a much lower dollar value than his initial $27,200 claim.
In all three cases, the court said that the exchange was guilty of negligence, as they could have allocated more resources in terms of security to prevent the massive data breach incident.
The judge, however, found both Bithumb and Jang partially responsible, noting that the victim provided details that were not originally included in the data which was exfiltrated from the exchange.
The total amount Jang get is $ 5,000 of the original amount, so it seems that you will not get back much if there is a hack happen to the platform you are trading on.
