No abuse reports filed yet — this domain is waiting for the next cycle of our automated abuse-reporter. ## TIMELINE ---------------------------------------------------------------- First detected: 2026-06-28 11:56:23 UTC (by PhishDestroy tracker) Last verified: 2026-07-01 16:20:35 UTC Current status: ACTIVE / observable ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019f0da7-44e7-73de-bf05-181b0a5ba5fb/ Wayback Machine: https://web.archive.org/web/*/saiyuuuo.github.io crt.sh CT logs: https://crt.sh/?q=%25.saiyuuuo.github.io Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=saiyuuuo.github.io AlienVault OTX: https://otx.alienvault.com/indicator/domain/saiyuuuo.github.io URLhaus: https://urlhaus.abuse.ch/host/saiyuuuo.github.io/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-06-28 12:00:18 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] This domain, saiyyuuuo.github.io, is identified as a high-risk phishing endpoint hosted on GitHub Pages infrastructure. Analysis indicates it operates as a credential harvesting site, likely targeting users through cloned authentication portals for popular services. No specific brand impersonation or drainer kit signature has been confirmed, though the generic_phishing classification suggests broad targeting of login credentials across multiple platforms. The domain exhibits no overt branding, increasing its versatility for threat actors to adapt templates dynamically. Technical indicators reveal the domain is flagged by 4 out of 95 security vendors on VirusTotal, with a detection ratio of 0.042. It is registered through GitHub, Inc., leveraging the platform’s legitimate hosting service to evade initial scrutiny. The domain resolves to the IP address 185.199.108.153, a known GitHub Pages server, which complicates network-based blocking due to shared infrastructure. No creation date is publicly available, as GitHub Pages domains are dynamically generated upon repository creation. Google Safe Browsing (GSB) status is currently unconfirmed, though historical blocklist data indicates prior inclusion in at least two threat intelligence feeds. Infrastructure analysis reveals no additional subdomains or associated certificates, suggesting a standalone operation. As of the latest assessment, saiyyuuuo.github.io remains active, with no takedown or repository deletion observed. Response actions by GitHub have not been confirmed, though the platform’s abuse reporting mechanisms may have been engaged. The remaining risk is classified as high due to the domain’s operational status, low detection rate, and reliance on trusted hosting infrastructure. Organizations are advised to implement network-level blocking of the domain and IP 185.199.108.153, while endpoint protection systems should prioritize signatures matching the 4 existing detections. Users should be educated to verify URLs before entering credentials, particularly on pages hosted under github.io, as threat actors continue to exploit legitimate services for phishing campaigns. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon MD5: b8a0bf372c762e966cc99ede8682bc71 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 (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/saiyuuuo.github.io/ JSON API: https://api.destroy.tools/v1/check?domain=saiyuuuo.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: volunteer-driven open-source threat-intelligence platform.
