Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] Is proposal-sei.xyz a Phishing Site Targeting Business Proposals? Analysis of the domain proposal-sei.xyz indicates it is an active phishing site under investigation as of July 25, 2026. The domain was registered on July 23, 2026, through NICENIC INTERNATIONAL GROUP CO., LIMITED, a registrar frequently associated with high-risk domains. Infrastructure analysis reveals the domain resolves to the IP address 104.21.43.40 and utilizes Cloudflare nameservers (leonidas.ns.cloudflare.com and monika.ns.cloudflare.com), a configuration commonly observed in phishing campaigns to obscure hosting origins and evade detection. At the time of this report, the domain appears on one security blocklist, and it is actively blocked by PhishDestroy, a specialized anti-phishing service. No detections were recorded by the 91 vendors that scanned the domain on VirusTotal, though the absence of detections does not confirm safety. The domain remains operational, and its content has not been fully analyzed for specific phishing tactics or targeted brands. Defenders should treat proposal-sei.xyz as a potential threat, particularly given its recent registration and use of Cloudflare infrastructure, which may indicate an attempt to exploit trust in business-related communications. Monitoring for additional blocklist inclusions and further vendor detections is recommended to assess its evolving risk profile. ## EVIDENCE HASHES ---------------------------------------------------------------- PhishDestroy Case ID: PD-20260725-042F82 Favicon MD5: 301f6569db4b13178c95c2eeb35140e4 TLS cert SHA-256: a4d5f87d2343b55c8901131af7deb3064b4be328fb610722dccbfd041aa9b826 ## 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/proposal-sei.xyz/ JSON API: https://api.destroy.tools/v1/check?domain=proposal-sei.xyz 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.
