“Rackspace Webmail: Hosted Email for Business”
証拠の概要
Analysis of tsor.info shows the site was registered on February 21 2026 through Cloudflare, Inc. The domain resolves to 66.135.18.64, an address owned by AS20473 The Constant Company, LLC in the United States. No TLS certificate is presented, and an HTTP GET returns a 200 response with the page title “Rackspace Webmail: Hosted Email for Business”, indicating an explicit attempt to impersonate Rackspace’s webmail service. The domain is listed on Cloudflare’s authoritative name servers jule.ns.cloudflare.com and ezra.ns.cloudflare.com.
Threat intelligence sources flag the site as a brand‑impersonation campaign targeting Rackspace; 16 of 95 VirusTotal scanners have marked the host as malicious, and it appears on at least one public blocklist and one AlienVault OTX pulse. PhishDestroy has already taken the domain offline, and current status is reported as offline. The available evidence confirms that the infrastructure was deliberately crafted to lure Rackspace users, but the lack of an SSL certificate and the offline status limit immediate observation of any credential‑harvesting page.
No additional indicators such as payload hashes, phishing URLs, or malware samples have been released, leaving the full scope of the campaign uncertain. Defenders should continue to block the domain at perimeter filters, monitor for any future resolution to the same IP or similar Cloudflare‑hosted nameserver pairs, and add the domain to internal IOC lists. Given the recent registration date and the relatively high VirusTotal detection count, organizations should also educate users about unsolicited Rackspace webmail login requests and enforce multi‑factor authentication for all Rackspace accounts.
