kucoin18[.]org

This domain, kucoin18.org, has been identified as a brand impersonation threat specifically targeting KuCoin, a prominent cryptocurrency exchange platform. Analysis indicates the site was designed to deceive users into believing they were interacting with the legitimate KuCoin interface, likely for the purpose of credential theft or unauthorized account access. The page title 'Welcome' and detected technologies suggest a front-end framework consistent with phishing kits used in crypto-related fraud campaigns. No direct evidence of a cryptocurrency drainer kit was observed, though the infrastructure aligns with credential harvesting tactics commonly employed in such schemes. Technical indicators reveal multiple red flags associated with kucoin18.org. The domain was registered on July 20, 2025, through Gname.com Pte. Ltd., a registrar frequently associated with suspicious registrations. It resolves to the IP address 104.21.80.1, which is part of a content delivery network known for hosting both legitimate and malicious content. At the time of analysis, the domain appeared on one security blocklist and was flagged by 4 out of 95 security vendors on a malware aggregation platform. The Gridinsoft trust score of 0/100 further corroborates its malicious classification. Detected technologies include Vue.js, HSTS, and Cloudflare infrastructure, which may have been leveraged to obfuscate the site's true intent and evade detection. As of the latest assessment, kucoin18.org has been taken offline, reducing immediate exposure risk to potential victims. However, the domain's infrastructure and registration details remain a concern, as threat actors may repurpose similar domains or IPs for future campaigns. Users who may have interacted with this site are advised to reset credentials associated with KuCoin or other cryptocurrency services immediately. Organizations should monitor for domains registered through the same registrar or resolving to the identified IP range, as these may indicate follow-up attacks. The elevated risk level persists due to the targeted nature of the impersonation and the potential for credential reuse across platforms.
