Coinone says hackers breached its outsourced customer-support vendor, exposing national ID and bank account numbers | #hacking | #cybersecurity | #infosec | #comptia | #pentest | #hacker

The records cover information customers left during chat and phone support: the phone number used for the call, name, email, date of birth, bank account number, password, resident registration number, ID card issue date, home address, crypto wallet address and transaction ID (TXID) [1]. Coinone said the list covers every item that could have been exposed and that the actual data differs by customer; it plans a lookup service so people can check what applies to them [1].Coinone said every login requires a second factor, an OTP or KakaoTalk verification on the customer’s own phone, so the leaked details alone cannot be used to log in or withdraw assets [1]. It told customers who shared a password with support to change it, along with the same password on other sites, and warned that fraudsters may pose as Coinone using details from past support conversations [1][2].
