Coinone warns of phishing, identity theft after customer data breach

Coinone said an attacker accessed servers operated by its outsourced customer support provider MetaM on Thursday and viewed or extracted customer support records. Potentially exposed data includes names, phone numbers, email addresses, dates of birth, bank account numbers, passwords, national ID numbers, addresses, wallet addresses and transaction IDs, varying by customer. Coinone did not disclose how many customers were affected, says its account, trading and wallet systems show no direct compromise, and has reported the incident to South Korean authorities.
