Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] docsign.dn3.co Safety Check — Phishing Campaign Detected This domain, docsign.dn3.co, was registered through Porkbun on 12 September 2022 and is currently hosted on Cloudflare infrastructure, indicated by the authoritative nameservers jihoon.ns.cloudflare.com and mallory.ns.cloudflare.com. The domain resolves to the IP address 172.67.142.187, which belongs to a Cloudflare edge node. TLS termination is provided by Google Trust Services under the WE1 certificate, demonstrating a valid HTTPS configuration that may lend credibility to malicious pages. Google Safe Browsing has classified the domain under the SOCIAL_ENGINEERING category, and VirusTotal reports that 9 of 91 scanned security vendors flag it as malicious. The combination of a relatively recent creation date, use of reputable CDN services, and active detection by multiple security tools aligns with a high-risk generic phishing profile. The threat remains active as of the report date. Defenders should treat the domain as hostile: block outbound connections to the IP, add the fully qualified domain to URL filtering lists, and monitor DNS queries for the domain. Continuous re-evaluation is advised, as the underlying infrastructure can shift behind Cloudflare's dynamic edge network. ## EVIDENCE HASHES ---------------------------------------------------------------- PhishDestroy Case ID: PD-20260718-A79361 TLS cert SHA-256: 0645775ddd01ff7013d4c4489f3dbd18b3d5df79d3335e0c61fc3c8ce97df609 ## 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/docsign.dn3.co/ JSON API: https://api.destroy.tools/v1/check?domain=docsign.dn3.co 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.
