x-security[.]org

Analysis of x-security.org shows a newly registered domain (created May 14, 2026) that resolves to the Vercel‑hosted IP 76.76.21.21 in the United States. The site presents the page title “X Security Holding — Преміум холдинг безпеки” and serves a valid Let's Encrypt R13 certificate, but returns an HTTP 307 redirect, suggesting an attempt to steer visitors to a secondary location. Infrastructure data lists five nameservers (nsa4.srv53.org, nsb3.srv53.org, nsc3.srv53.org, nsd3.srv53.org, nsa3.s...), indicating use of a shared DNS service. Reputation metrics are poor: Gridinsoft assigns a trust score of 0/100, the domain appears on three security blocklists, and it is actively blocked by PhishDestroy, MetaMask, and SEAL. VirusTotal reports two detections out of 92 scanners, and AlienVault OTX references a single pulse linking the domain to malicious activity. The combination of a high‑risk classification, active blocklist listings, and recent registration points to a deliberate phishing operation, though the exact payload or targeted brand remains unverified because the page content has not been examined. Defenders should immediately block DNS resolution for x-security.org, add the domain to intrusion‑prevention and email‑filtering rules, and monitor for any related C2 traffic from the associated IP range. Continued observation of the nameserver set and any new detections is recommended to assess potential campaign evolution.
