kucoiin-customer-ssupport-numbber[.]webflow[.]io

This domain, kucoiin-customer-ssupport-numbber.webflow.io, is identified as a brand impersonation threat targeting KuCoin, a prominent cryptocurrency exchange platform. Analysis confirms the domain was designed to deceive users by presenting itself as an official customer support portal, complete with fabricated contact numbers and account access guidance. The current status of the domain is offline, though prior activity suggests it was actively used in fraudulent operations to mislead victims seeking legitimate assistance. Infrastructure analysis reveals critical technical indicators associated with this threat. The domain was flagged by 19 of 95 security vendors on VirusTotal, indicating broad recognition of its malicious nature. It was registered through NameCheap, Inc. on February 21, 2026, an unusually future-dated entry that may suggest registry manipulation or an attempt to evade detection. The domain resolved to IP address 172.64.151.8, hosted on Cloudflare infrastructure (AS13335), a common tactic to obscure the true origin of phishing sites. An SSL certificate issued by Google Trust Services (WE1) was present, lending a superficial layer of legitimacy. The domain appeared on one security blocklist, specifically PhishDestroy, further corroborating its fraudulent intent. The risk level for this domain is assessed as elevated due to its targeted impersonation of a high-value cryptocurrency brand and the use of technical obfuscation techniques. While the domain is currently offline, users who may have interacted with it should take immediate action. It is recommended to verify all communications through official KuCoin channels only, avoid clicking on unsolicited links, and monitor accounts for unauthorized activity. Organizations should update blocklists to include this domain and its associated IP address, and security teams should review logs for any prior engagement with the site. Proactive measures, such as user education on recognizing brand impersonation tactics, are essential to mitigate similar threats in the future.
