## ANALYST NARRATIVE
----------------------------------------------------------------

Additionally, it appears on one security blocklist and is actively blocked by Maltrail, highlighting its reputation as a known malicious infrastructure.  To mitigate risks associated with crypto drainer phishing sites like underpt.cyou, users should avoid clicking on unsolicited links or downloading attachments from unknown sources. Always verify the legitimacy of websites by checking domain age, SSL certificates, and community blocklists. If in doubt, consult PhishDestroy for real-time threat intelligence and safe browsing guidance.

## EVIDENCE HASHES
----------------------------------------------------------------
PhishDestroy Case ID:  PD-20260507-FDCA0D
TLS cert SHA-256:      84a5c33c0c2eb7383101824a9c48ee64e5abc1c367b8a105753c215585100e9f

## 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.
