double0[.]xyz

Analysis of the domain double0.xyz, created on 21 February 2026 and currently taken offline, shows multiple indicators of malicious activity consistent with a generic phishing operation. The domain is registered through PDR Ltd. d/b/a PublicDomainRegistry.com and uses Cloudflare nameservers lamar.ns.cloudflare.com and sarah.ns.cloudflare.com. DNS resolution points to IP address 188.114.97.3, which belongs to AS13335 Cloudflare, Inc., and is geolocated in the United States. No TLS certificate is present, indicating that the site was served without HTTPS encryption. VirusTotal reports that 11 of 93 scanned security vendors flagged the domain, reinforcing the suspicion of abuse.

Google Safe Browsing classifies the URL as a social‑engineering threat, and AlienVault OTX includes the domain in a single threat‑intel pulse. The page title returned from the site is “Web Development Studio,” but no further content analysis is available because the service is offline. Reputation scoring from Gridinsoft assigns a trust score of 0 / 100, the lowest possible rating. The domain appears on two public blocklists and is actively blocked by PhishDestroy and ScamSniffer.

Overall, the observable evidence—registrar information, Cloudflare hosting, lack of TLS, low trust score, multiple vendor detections, and inclusion on blocklists—corroborates the classification as a high‑risk phishing host. Defenders should add double0.xyz and its resolving IP 188.114.97.3 to network deny lists, ensure that email filters reference the listed blocklists, and monitor Cloudflare‑associated address ranges for related activity. Because the site is offline, continuous probing is not possible, but periodic re‑resolution of the domain is recommended to detect any re‑activation. The combination of vendor detections, Safe Browsing flag, and blocklist presence justifies immediate mitigation.
