Coinone Customer Service Outsourcing Vendor Server Breached, User Inquiry Data Leaked

on November 15, according to an official announcement from Coinone, the server of its customer consultation outsourcing provider MetaM was illegally accessed by external attackers on November 12, resulting in customer consultation information stored on the server being viewed or leaked. Users without customer center consultation records were not affected by this data breach.

Coinone stated that the potentially leaked information may include names, phone numbers, email addresses, passwords, account numbers, and wallet addresses provided by users during chat or phone consultations, with specific details varying by individual. The company's member accounts, trading operations, and cryptocurrency asset wallet systems are isolated from the outsourcing contractor's server, and no signs of direct intrusion have been detected as of now.

The company has transitioned outsourced customer service to email-based inquiries, blocked unauthorized access pathways, reported the incident to relevant authorities, and is conducting an investigation alongside the outsourcing contractor and professional cybersecurity firms.
