Hosting org: AS13335 Cloudflare, Inc. Registrar: Cloudflare, Inc. Nameservers: ["kevin.ns.cloudflare.com", "marjory.ns.cloudflare.com"] Registered: 2018-07-07 Page title: Rackspace Webmail: Hosted Email for Business ## TLS CERTIFICATE ---------------------------------------------------------------- Issuer: none Status: INVALID chain ## ABUSE-REPORT HISTORY (evidence of registrar non-response) ---------------------------------------------------------------- Status: CLOSED — no report required. This domain was neutralised before the abuse-report cycle could be dispatched — either the hosting provider / registrar suspended it on their own, the DNS went dead, or the operator abandoned the infrastructure. PhishDestroy keeps the evidence bundle on file for audit but no formal notice was sent. ## TIMELINE ---------------------------------------------------------------- Domain registered: 2018-07-07 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-02-25 02:39:27 UTC (by PhishDestroy tracker) First reported: 2026-02-21 03:20:45 UTC (abuse notice filed) Last verified: 2026-06-26 04:20:34 UTC Neutralised: 2026-04-13 06:00:53 UTC Current status: taken down (registrar suspended or DNS dead) ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019c7d90-a1b4-72e9-8c0d-77ff08853a73/ Wayback Machine: https://web.archive.org/web/*/criterion-est-connections-periodic.trycloudflare.com crt.sh CT logs: https://crt.sh/?q=%25.criterion-est-connections-periodic.trycloudflare.com Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=criterion-est-connections-periodic.trycloudflare.com AlienVault OTX: https://otx.alienvault.com/indicator/domain/criterion-est-connections-periodic.trycloudflare.com URLhaus: https://urlhaus.abuse.ch/host/criterion-est-connections-periodic.trycloudflare.com/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-06-25 19:54:09 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] The domain criterion-est-connections-periodic.trycloudflare.com is flagged for an elevated-risk brand impersonation threat targeting Rackspace, a well-known cloud computing and managed hosting provider. The threat does not involve any crypto drainer kits but is designed to deceive users into believing they are interacting with a legitimate Rackspace service. Analysis indicates that the domain has been flagged by 24 out of 95 security vendors on VirusTotal, suggesting a significant level of suspicion among the cybersecurity community. The domain is registered through Cloudflare, Inc., and resolves to the IP address 104.16.231.132, which is located in the United States and is part of the AS13335 Cloudflare, Inc. network. The domain was created on July 07, 2018, and it appears on one security blocklist. The page title found on the domain is 'Rackspace Webmail: Hosted Email for Business,' further supporting the brand impersonation threat. The current status of the domain is offline, indicating that it has been taken down or is no longer active. Despite this, the domain remains a point of concern due to its previous malicious activities and the elevated risk level. Organizations and individuals should remain vigilant and ensure that their security measures are up to date to prevent any potential residual risks. It is recommended to avoid interacting with any links or services associated with this domain and to report any suspicious activities to the relevant authorities or security teams. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon SHA-256: 63440a8fca600cf5710c2dc163c88d6b1ba2314b88929b18864dc38f3028b698 ## SCORING METHODOLOGY ---------------------------------------------------------------- Composite score is NOT derived from VirusTotal alone. PhishDestroy aggregates: - VirusTotal positive ratio - Public blocklist consensus (MetaMask, ScamSniffer, OpenPhish, PhishTank, URLhaus, CryptoFirewall, SEAL, Polkadot, Enkrypt, Phishunt, DiscordPhishing, PhishingDB) - Cloaking detection (HTTP 666 or rendering delta between bot and real visitor) - DNS-filter consensus (Quad9, CleanBrowsing, NextDNS, AdGuard, Cloudflare, etc.) - AlienVault OTX pulses + Cloudflare Radar + Google Safe Browsing - URLScan / URLQuery verdicts - Brand-impersonation heuristics (DOM analysis of forms, logos, wording) - Known phishing-kit fingerprinting (favicon hash, JS obfuscation signatures) - Wallet-drainer family classification (Angel, MS, Rainbow, Pink, Inferno, ...) - Free-TLS vs paid-cert ratio (throwaway infrastructure signal) - Registrar/hosting abuse history (this registrar's track record) - Human researcher sign-off (volunteer takedown team) A domain present in our database is ALREADY flagged. A low VT count by itself does NOT mean the domain is safe — new scam domains routinely show 0/95 VT for their first 7–30 days while actively draining wallets. Always cross-reference the composite score and the individual indicators above, not just VT. ## CORRECTIONS / APPEALS ---------------------------------------------------------------- Full HTML report: https://phishdestroy.io/domain/criterion-est-connections-periodic.trycloudflare.com/ JSON API: https://api.destroy.tools/v1/check?domain=criterion-est-connections-periodic.trycloudflare.com Appeal a flag: https://phishdestroy.io/appeals/ (responded to within 48 hours, FP rate <0.01%) Submit a report: https://t.me/PhishDestroy_bot About PhishDestroy: volunteer-driven open-source threat-intelligence platform.
