The Communications Commission of South Korea (KCC) fined Bithumb's largest trading platform for 60 million won ($ 55,000) "for allegedly leaking the private data of its users”. This is reported by the Yonhap.
According to the commission, hackers twice abducted personal data of Bithumb users: in April, data leakage of 31,506 users occurred, and in July - 3,434 users of the exchange.
We took into consideration the fact that the vulnerability occurred due to failure to comply with the safeguards clause and was directly or indirectly exploited by the hacker. Personal information was leaked and monetary damage occurred. The punitive action was taken as the operator did not comply with protective steps, making it vulnerable to hacks and causing leaks of personal data and financial damage.
It is also worth noting that there is no additional information on this situation at official Bithumb website or Twitter.
