linktron64[.]worker-ef3f16fe[.]workers[.]dev

The domain linktron64.worker-ef3f16fe.workers.dev was observed as an offline cryptocurrency‑related phishing infrastructure on July 24, 2026. Registration data shows the domain was created on February 08, 2019 and was provisioned through Cloudflare, Inc., using the authoritative nameservers clyde.ns.cloudflare.com and sofia.ns.cloudflare.com. DNS resolution points to IP address 104.21.31.129, which belongs to Cloudflare’s AS13335 network and is geolocated to the United States. The TLS certificate presented for the host is issued by Google Trust Services under the WE1 label, indicating the site was served over HTTPS with HSTS enabled.

HTTP probing returned a 404 status code and the page title "Coming Soon," confirming that the site currently hosts no active content. Automated scanning on VirusTotal recorded a single positive detection out of 93 security vendors, and the domain is listed on one public blocklist operated by PhishDestroy. Additional fingerprinting identified the use of Cloudflare’s edge services and support for HTTP/3. The available intelligence does not include any captured payload, login forms, or malicious scripts, so the exact phishing vector remains unverified beyond the classification as a crypto scam.

Defenders should immediately block the FQDN at perimeter filters, add the IP address 104.21.31.129 to network‑level deny lists, and monitor for any re‑registration attempts or new subdomains that resolve to the same Cloudflare edge. Continuous observation of the Cloudflare nameserver set may reveal future deployments, and correlation with other domains sharing the same IP or certificate could surface related campaigns. Until more detailed content is obtained, the precautionary measures outlined provide the most effective mitigation against potential credential harvesting or cryptocurrency theft attempts associated with this infrastructure.
