kucoinleogin[.]gitbook[.]io

Analysis of the domain kucoinleogin.gitbook.io indicates confirmed brand impersonation targeting KuCoin, a cryptocurrency exchange. The domain was registered on February 21, 2026, through Cloudflare, Inc., and currently resolves to the IP address 172.64.147.209, hosted on Cloudflare's infrastructure (AS13335). Nameservers dahlia.ns.cloudflare.com and hugh.ns.cloudflare.com further confirm Cloudflare as the DNS provider. The site was flagged by 13 of 93 security vendors on VirusTotal, with detection categorized as a crypto scam.

It appears on one security blocklist and is blocked by PhishDestroy. The page title, 'KuCōin - us login | KuCoin: Log In | Sign In,' explicitly mimics KuCoin's branding, including a Unicode character substitution ('ō' for 'o') likely intended to evade basic detection mechanisms. The domain returned an HTTP 403 status at the time of assessment, suggesting it was either taken offline or restricted access. SSL certification is provided by Google Trust Services (WE1), and the site employs HSTS and HTTP/3, which are common in both legitimate and malicious sites leveraging Cloudflare's services.

No evidence of a phishing kit or additional infrastructure was provided, limiting further classification of attack methodology. Defenders should treat this domain as high-risk for KuCoin users and prioritize blocking it at the DNS or network level. Given the detection count and blocklist presence, retrospective analysis of logs for connections to 172.64.147.209 or the domain itself is recommended to identify potential compromised accounts or credential harvesting activity. The Unicode character in the page title may also serve as a signature for detecting similar impersonation attempts.
