Is 13903.xyz a phishing site?

Analysis indicates that the domain 13903.xyz is currently active and serves a generic phishing threat. The site returns HTTP 200 responses, confirming it is reachable. It is listed on a single security blocklist and is flagged by Google Safe Browsing for social engineering, demonstrating that major web safety services recognize malicious intent. VirusTotal scans show that 15 of 95 security vendors have flagged the domain, providing additional corroboration of its risk profile. The domain is also blocked by the PhishDestroy feed, reinforcing its classification as a phishing source. While the available intelligence confirms the domain’s malicious status, details such as the underlying hosting infrastructure, registration data, or targeted brands have not been disclosed, leaving those aspects uncertain. Defenders should proactively block 13903.xyz at network perimeter devices, update intrusion detection signatures, and monitor outbound connections for any attempts to contact the domain. Continuous re‑evaluation is recommended, as the threat landscape may evolve and additional indicators could emerge.

## EVIDENCE HASHES
----------------------------------------------------------------
TLS cert SHA-256:      39731d1b60cb7214c0358d0da6b3c6fdd8ddb2b70cdd7efe0f11032bf5477386

## 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.
