A significant cybersecurity incident impacting Coincheck occurred on May 31, 2020. Attackers successfully compromised the exchange's domain registrar account, leading to the hijacking of its primary domain name. This breach allowed the hackers to manipulate DNS records, redirecting legitimate email communications intended for Coincheck users to servers controlled by the attackers. Utilizing this access, the perpetrators executed spear-phishing campaigns specifically targeting Coincheck customers. Approximately 200 users interacted with these fraudulent communications. The exchange detected the ongoing attack through anomalies in network traffic patterns, enabling its security team to intervene and regain control of the compromised domain. Coincheck reported that no confirmed theft of customer funds or breaches of user accounts resulted directly from this specific domain hijacking and phishing incident, highlighting their detection and mitigation efforts during this event.
