hyrdf[.]top

On July 22, 2026, the domain hyrdf.top was observed to be taken offline but remains listed as a brand‑impersonation threat targeting x.com. The site was registered on December 5 2025 through NiceNIC International Group Co., Limited and is hosted behind Cloudflare (AS13335) with the IP address 104.21.62.163 located in the United States. DNS resolution uses the Cloudflare nameservers harlan.ns.cloudflare.com and lisa.ns.cloudflare.com, and the service is reachable via HTTP/3. The TLS certificate is issued by Google Trust Services under the WE1 root, indicating a valid HTTPS endpoint despite the malicious intent.

VirusTotal scans returned three positive detections out of ninety‑five submitted engines, and the domain appears on a single public blocklist operated by PhishDestroy. Gridinsoft assigned a trust score of 0 / 100, reflecting a high confidence of abuse. The only page content captured is the default nginx title “Welcome to nginx!”, offering no further clues about the payload or login flow.

Because the domain is currently offline, active exploitation cannot be confirmed, but the presence of a valid SSL certificate, Cloudflare edge, and multiple vendor detections suggests it was prepared for credential‑ harvesting. Defenders should continue to block hyrdf.top at network perimeter and DNS layers, add the IP to threat‑intel feeds, and monitor for any re‑appearance or similar domains registered by the same registrar. Ongoing vigilance is recommended, especially for users of x.com, to prevent potential credential compromise.
