## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-07-26 10:35:09 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.]

Is h21b.top a Phishing Site?

Analysis indicates that h21b.top is currently active and resolves to a web server that returns HTTP 200. The domain was registered through NameMart Pte. Ltd. and uses four nameservers under the 1111343.com zone. It appears on a single security blocklist and is listed by PhishDestroy as blocked. VirusTotal has recorded detections from six of ninety‑one scanning engines, confirming that at least a subset of security vendors consider the domain malicious.

No public Safe Browsing or OTX entries are available in the supplied data, and no SSL certificate details have been disclosed. The page title and content have not been captured, so the exact lure or credential‑harvesting technique remains unknown. The limited visibility suggests that the infrastructure is deliberately minimal, likely to reduce attribution surface.

Defenders should continue to block the domain at perimeter and DNS levels, monitor for any traffic to the listed nameservers, and consider adding the domain to internal blocklists. Ongoing observation of the hosting provider and periodic rescanning with VirusTotal or similar services are advised to detect any changes in detection ratios. Because the domain is already flagged by multiple vendors and a dedicated anti‑phishing feed, organizations should treat any email or web reference to h21b.top as high‑risk and enforce strict user awareness controls.

## EVIDENCE HASHES
----------------------------------------------------------------
TLS cert SHA-256:      3b137e80b317dd92bec10080b70afa74ebcab217ffca2eed9c7bb67497f07430

## 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.
