Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] PhishDestroy identifies signaturerepository.xyz as a live credential-harvesting phishing domain currently under active investigation. The infrastructure is designed to trick visitors into surrendering login credentials under the guise of a legitimate repository service. No specific brand is yet confirmed as impersonated, but the operational pattern aligns with high-volume identity-theft campaigns. This domain was flagged by 0 of 95 VirusTotal vendors at the time of analysis, indicating it remains undetected by most antivirus engines. It was registered through NICENIC INTERNATIONAL GROUP CO., LIMITED, resolves to IP 104.21.3.75, and holds a Let's Encrypt SSL certificate. The domain was created on October 23, 2025, placing it less than one week old at detection time. Current blocklist count is 0, and domain trust scores are critically low due to age and suspicious infrastructure. PhishDestroy recommends blocking signaturerepository.xyz at the network perimeter and disabling access via DNS sinkholing. Users who may have entered credentials should immediately rotate passwords on all related accounts and enable multi-factor authentication where available. Monitor outbound traffic for connections to 104.21.3.75 and flag any unusual authentication requests from this IP range. Organizations are advised to update threat intelligence feeds and firewall rules to block this domain and its associated IP until further analysis is complete. [Updates since narrative was generated:] - VirusTotal detections: now 1/94 (narrative was written when count was lower) ## EVIDENCE HASHES ---------------------------------------------------------------- PhishDestroy Case ID: PD-20260328-3DF042 ## 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/signaturerepository.xyz/ JSON API: https://api.destroy.tools/v1/check?domain=signaturerepository.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: volunteer-driven open-source threat-intelligence platform.
