kocuinloginu[.]webflow[.]io

This domain, kocuinloginu.webflow.io, poses a direct threat to users of the KuCoin cryptocurrency exchange by impersonating its official login interface. The site presents itself as a "KuCoin Login Guide | Step-by-Step Access to Your Exchange," designed to deceive users into entering their credentials. Once submitted, these credentials are harvested by threat actors, enabling unauthorized access to victims' exchange accounts, potential theft of funds, and further exploitation such as phishing campaigns or crypto draining attacks. The use of a seemingly legitimate guide format increases the likelihood of successful deception, particularly among users unfamiliar with secure authentication practices. Analysis indicates this domain was created on March 06, 2026, and is registered through MarkMonitor, Inc., a registrar commonly used for both legitimate and malicious domains. The domain is flagged by 19 out of 95 security vendors on VirusTotal, a clear indicator of its malicious nature. Additionally, it appears on one security blocklist, further confirming its classification as a threat. Infrastructure analysis reveals the domain resolves to the IP address 172.64.151.8, hosted on Cloudflare's network (AS13335), which is frequently leveraged by threat actors to obfuscate their operations and evade detection. The SSL certificate, issued by Google Trust Services (WE1), adds a layer of apparent legitimacy, though it does not mitigate the underlying malicious intent. Users who have visited kocuinloginu.webflow.io or entered credentials on this site should take immediate action to mitigate potential risks. First, revoke access to any active sessions on the legitimate KuCoin platform and change the account password using a secure, unrelated device. Enable multi-factor authentication (MFA) if not already active, and monitor the account for unauthorized transactions or suspicious activity. If funds have been transferred without authorization, report the incident to KuCoin support and relevant law enforcement or cybercrime reporting agencies. Additionally, scan the device used to access the site for malware, as credential harvesters often deploy secondary payloads. Finally, review connected applications or API keys linked to the account and revoke any that are unrecognized or unnecessary.
