No abuse reports filed yet — this domain is waiting for the next cycle of our automated abuse-reporter. ## TIMELINE ---------------------------------------------------------------- First detected: 2026-07-19 12:38:03 UTC (by PhishDestroy tracker) Last verified: 2026-07-23 00:22:22 UTC Current status: ACTIVE / observable ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-07-20 01:50:51 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] Is yubico-app.com a Cloudflare Impersonation Scam? Analysis of the domain yubico-app.com, registered through Dynadot Inc, indicates active brand impersonation targeting Cloudflare. The domain resolves to the IP address 188.114.96.3, which is geolocated in Canada and associated with Cloudflare, Inc. Nameservers are configured as damian.ns.cloudflare.com and yolanda.ns.cloudflare.com, suggesting an attempt to mimic legitimate Cloudflare infrastructure. The SSL certificate is issued by Google Trust Services (WE1), a common provider for both legitimate and malicious domains, offering no definitive indication of intent. The domain is currently active, returning an HTTP 403 status with the page title 'Suspected Malware | Cloudflare,' which aligns with known patterns of brand impersonation. It appears on one security blocklist and is flagged by PhishDestroy. As of the latest scan, 17 out of 91 security vendors on VirusTotal detect this domain as malicious. The scam type is explicitly classified as brand impersonation, with Cloudflare identified as the targeted brand. Defenders should note that while the domain exhibits multiple indicators of malicious activity, its association with Cloudflare’s IP range may complicate network-based blocking. The use of Cloudflare nameservers and a Cloudflare-hosted IP suggests an effort to blend into expected traffic patterns. No evidence of a phishing kit or specific payload is currently available, and the exact content served by the domain remains unconfirmed. Organizations are advised to block the domain at the DNS or proxy level and monitor for related infrastructure using the same nameserver or IP patterns. Further investigation into the registration details and historical DNS records may provide additional context for takedown efforts. ## EVIDENCE HASHES ---------------------------------------------------------------- TLS cert SHA-256: 881c7aa000385186926ced5af0366d86338b5ed5ac63e281c71b7531108b785b ## 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 (operator 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/yubico-app.com/ JSON API: https://api.destroy.tools/v1/check?domain=yubico-app.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: independent open-source threat-intelligence platform.
