South Korean crypto exchange Coinone warned customers about possible phishing and identity theft after an attacker accessed servers run by its outsourced support provider, MetaM, and viewed or extracted customer support records. Coinone said the information potentially exposed includes names, contact details, dates of birth, bank account numbers, passwords, national identification numbers, home and wallet addresses, and transaction IDs.
Coinone said the affected information varies by customer, and people who never contacted its support center were unaffected. It did not say how many customers were affected. The exchange urged customers who shared passwords with support staff to change them and said it had no evidence that its separate account, trading or wallet systems were directly compromised.
