# PhishDestroy threat dossier — opensea-site.github.io ================================================================ Fetched: 2026-07-13 09:11:42 UTC Canonical: https://phishdestroy.io/domain/opensea-site.github.io/ ## VERDICT ---------------------------------------------------------------- TAKEN DOWN (neutralised) Composite threat score: 100/100 (PhishDestroy scoring — see methodology below) Scam classification: NFT Scam Targeted brand: OpenSea ## DETECTION EVIDENCE ---------------------------------------------------------------- VirusTotal: 3/91 security vendors flagged this domain Flagging vendors: ChainPatrol, alphaMountain.ai, Kaspersky URLQuery: -1 detections Public blocklists: listed on 3 independent blocklists ## INFRASTRUCTURE ---------------------------------------------------------------- IP address: 185.199.108.153 (US, San Francisco) ASN: AS54113 Fastly, Inc. Hosting org: GitHub, Inc Registrar: GitHub, Inc. Nameservers: NS_NOT_FOUND Registered: 2026-06-22 Page title: OpenSea - NFT Marketplace App HTTP response: 404 ## TLS CERTIFICATE ---------------------------------------------------------------- Issuer: Let's Encrypt / YR2 Expires: 2026-09-02 Status: INVALID chain Fingerprint: 32491b26bfaf7bfb556029ef32299ac4374db34d09eecd4ffd01f21b2c5a8567 Subject Alternative Names (related infrastructure — often same operator): - github.com - github.io - githubusercontent.com ## 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: 2026-06-22 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-07-04 12:36:52 UTC (by PhishDestroy tracker) Last verified: 2026-07-13 08:20:41 UTC Current status: taken down (registrar suspended or DNS dead) ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019f2cb2-bae5-752c-90f8-a609a4a613ab/ Wayback Machine: https://web.archive.org/web/*/opensea-site.github.io crt.sh CT logs: https://crt.sh/?q=%25.opensea-site.github.io Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=opensea-site.github.io AlienVault OTX: https://otx.alienvault.com/indicator/domain/opensea-site.github.io URLhaus: https://urlhaus.abuse.ch/host/opensea-site.github.io/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-07-04 13:15:34 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] This domain, opensea-site.github.io, is flagged as a high-risk brand impersonation threat specifically targeting OpenSea, a major non-fungible token (NFT) marketplace. Analysis indicates the page presents itself as the legitimate OpenSea platform, using the title 'OpenSea - NFT Marketplace App' to deceive users into interacting with fraudulent content. No explicit cryptocurrency drainer kit signatures were identified, but the site's structure and branding align with known phishing tactics designed to harvest credentials or wallet connections. Infrastructure analysis reveals the domain is hosted on GitHub Pages, resolving to the IP address 185.199.108.153. The domain is registered through GitHub, Inc., and currently holds a VirusTotal detection score of 3/95 security vendors. The SSL certificate is issued by Let's Encrypt, a common feature in both legitimate and malicious sites. Technologies detected include Varnish, Fastly, and HTTP Strict Transport Security (HSTS), which are often employed to enhance performance and security—though in this case, they serve to lend credibility to the fraudulent page. No Google Safe Browsing (GSB) or blocklist entries were identified at the time of analysis, though the low detection rate may reflect the domain's recent deployment or evasion techniques. As of the latest assessment, opensea-site.github.io remains active and continues to present a significant risk to users. The domain's hosting on a legitimate platform (GitHub Pages) complicates takedown efforts, as it leverages trusted infrastructure to evade initial scrutiny. Users are advised to verify the authenticity of NFT marketplaces by cross-referencing official domains and avoiding interaction with pages hosted on subdomains of development platforms. Organizations should monitor for similar impersonation attempts, particularly those using free hosting services to distribute phishing content. The remaining risk is classified as high due to the domain's operational status and targeted nature. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon MD5: aff772a03c1af6a7b409aeb56e07459b TLS cert SHA-256: 32491b26bfaf7bfb556029ef32299ac4374db34d09eecd4ffd01f21b2c5a8567 ## 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/opensea-site.github.io/ JSON API: https://api.destroy.tools/v1/check?domain=opensea-site.github.io 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.
