kucoim-login[.]gitbook[.]io

This domain, kucoim-login.gitbook.io, is actively flagged as a high-risk credential phishing site targeting KuCoin users. Infrastructure analysis reveals the domain was registered on March 30, 2014, through Cloudflare, Inc., and currently resolves to IP address 172.64.147.209, hosted on Cloudflare’s network in Canada. The page title, 'Kucoin Loℊin | Loℊ In Kucoin,' contains deliberate character substitutions (e.g., 'g' replaced with 'ℊ') to evade basic text-based detection while impersonating the legitimate KuCoin login portal. The domain is classified as a credential phishing site, consistent with the observed page title and brand impersonation. Security vendors have flagged this domain: 18 of 91 engines on VirusTotal detect malicious activity, and it appears on at least one blocklist. Google Safe Browsing categorizes the domain under 'SOCIAL_ENGINEERING,' further confirming its phishing classification. The domain employs Cloudflare nameservers (dahlia.ns.cloudflare.com and hugh.ns.cloudflare.com) and utilizes GitBook as its hosting platform, alongside Google Cloud and Cloudflare technologies, including HSTS and HTTP/3. The SSL certificate is issued by Google Trust Services (WE1), a common feature in both legitimate and malicious infrastructure. While the domain’s creation date predates typical phishing campaigns, this does not preclude its current malicious use. Defenders should treat this domain as active and high-risk, particularly for users attempting to access KuCoin services. The HTTP 307 redirect status suggests potential intermediary behavior, though the final destination remains unverified. No evidence indicates compromise of legitimate infrastructure, but the use of Cloudflare and GitBook may complicate takedown efforts. Organizations should block resolution to 172.64.147.209 and monitor for related subdomains or similar impersonation tactics.
