Bitkoex South Korean cryptoexchange, which was launched last month, reported on a leak of data of 19 Karma (KRM) tokens holders.
As Coindesk notes, the incident put at risk funds for a total of 750 million won ($ 620,000). Data contained email addresses of users of the trading platform, wallet addresses and private keys.
The problem arose because of the negligence of one of the employees of the recently opened trading floor. As it turned out, he published in the group chat of Kakao data on investments to Karma tokens, with the email addresses of the users of the trading platform and associated wallets, even with the relevant private keys.
Representatives of Bitkoex assured their clients that the actions were committed inadvertently. According to them, the funds that were compromised were immediately transferred to cold wallets, and therefore are in complete safety.
Last week largest South Korean exchange Bithumb was hacked. This event caused a significant response in the society and caused even greater tightening of the crypto regulation in the country.
