kuccoin-custtomer-sserrvice-nnumber[.]webflow[.]io

This domain is flagged for elevated-risk brand impersonation phishing, specifically targeting KuCoin users by masquerading as official customer support channels. The site presents itself as a legitimate contact portal for account access, using deceptive page titles such as 'Kucoin Customer Service number - Access Your Account Easily' and variations with intentional typographical errors to evade detection while mimicking the brand's identity. Analysis indicates this is a calculated attempt to harvest sensitive credentials or personal information under false pretenses, a common tactic in cryptocurrency-related phishing campaigns. Infrastructure analysis reveals the domain kuccoin-custtomer-sserrvice-nnumber.webflow.io was registered through Webflow on March 12, 2026, and resolves to IP address 104.18.36.248, hosted on Cloudflare’s network (AS13335). Security vendor detections on VirusTotal report 17/95 flags, while the domain appears on at least one security blocklist and is actively blocked by enterprise phishing detection systems. The SSL certificate is issued under the identifier WE1, and the domain is currently offline, though historical records confirm its prior operational status. The use of Cloudflare infrastructure is notable, as it provides anonymity and resilience against takedown efforts, complicating attribution and mitigation. Mitigation for this threat type requires a multi-layered approach. Organizations should immediately update web filtering policies to block the domain and its associated IP address, ensuring all endpoints are protected against potential redirects or cached malicious content. Security teams are advised to monitor for indicators of compromise, including unusual login attempts or support requests originating from users who may have interacted with the domain. User awareness training should emphasize the risks of engaging with unsolicited customer service links, particularly those containing typographical errors or hosted on third-party platforms. Additionally, KuCoin users should be directed to verify all official communications through the company’s authenticated channels, avoiding reliance on phone numbers or contact details presented on unverified sites.
