uxlinkmantlechainmigration[.]pages[.]dev

The domain uxlinkmantlechainmigration.pages.dev was registered on March 10, 2026 through Cloudflare, Inc. and resolves to the Cloudflare edge address 172.66.47.107, an IP located in the United States and announced by AS13335. The site presented the page title "Suspected phishing site | Cloudflare" and is classified as a brand‑impersonation campaign targeting the Mantle brand. No TLS certificate is associated with the domain, indicating that HTTPS is not in use. Infrastructure analysis shows the presence of HSTS, Cloudflare services, and HTTP/3 support, consistent with the hosting provider’s default configuration.

The domain’s trust score from Gridinsoft is 0 out of 100, and three independent blocklists have already listed the host. Google Safe Browsing flags the site for social engineering, and VirusTotal reports five detections out of ninety‑four scanned security vendors, confirming malicious activity. The domain has been taken offline and is currently blocked by PhishDestroy, MetaMask, and the SEAL consortium. Nameservers kellen.ns.cloudflare.com and raegan.ns.cloudflare.com further confirm Cloudflare control.

While the exact content of the landing page has not been examined, the combination of a brand‑impersonation claim, low trust score, multiple vendor detections, and active blocklist entries provides strong evidence that the domain was being used for phishing or credential harvesting against Mantle users. Defenders should continue to block the domain at DNS and proxy layers, monitor for any re‑hosting attempts using the same sub‑domain pattern, and update detection rules to include the observed IP address and Cloudflare name‑server pair. Incident response teams should also alert end users of Mantle to the existence of this impersonation attempt and advise against any interaction with URLs matching the uxlinkmantlechainmigration.pages.dev pattern.
