Coinone's customer service outsourcing provider's server was hacked, resulting in the leakage of some users' personal information.

On November 12, the server of the customer service outsourcing provider for the South Korean cryptocurrency exchange Coinone was illegally hacked by external attackers, resulting in the leakage of personal information of some users who had consulted the customer service center. The leaked information includes phone numbers, names, email addresses, dates of birth, bank account numbers, passwords, resident registration numbers, document issuance dates, home addresses, wallet addresses, and transaction IDs (TXIDs) provided by users during the consultation process, with specific details varying from person to person. Users without consultation records are unaffected. Coinone's member accounts, trading and virtual asset wallet systems are independent of the outsourced server, and no signs of direct intrusion have been found so far.
