u21n.vip Fake Login Portal Alert

Analysis of the domain u21n.vip indicates a high-risk phishing infrastructure active as of July 28, 2026. The domain is registered through NameMart Pte. Ltd. and currently resolves with an HTTP 200 status, suggesting an operational web server. Infrastructure review reveals four nameservers—ns1.1111343.com, ns2.1111343.com, ns3.1111343.com, and ns4.1111343.com—all of which are associated with prior malicious activity clusters.

The domain appears on one security blocklist (PhishDestroy) and is flagged by three of ninety-one security vendors on VirusTotal, though the specific detection rationale remains unverified. No brand impersonation has been confirmed in available metadata; the exact content served by the site is not yet analyzed. Defenders should treat this domain as hostile infrastructure, block resolution at DNS and proxy layers, and monitor for connections from internal endpoints.

Further investigation is warranted to determine the target brand or service, as well as potential credential-harvesting mechanisms. The domain's continued activity despite blocklist presence suggests ongoing malicious intent.

## EVIDENCE HASHES
----------------------------------------------------------------
TLS cert SHA-256:      a06f53b394bb7744b671df0b2a1dcbdb5141c27c370b787e96ce9ae4665d0457

## 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.
