ruiheng.dev Generic Phishing Alert

Analysis of ruiheng.dev shows a newly registered domain (creation date February 25, 2026) that is actively resolving to the IPv4 address 216.198.79.1. The domain is hosted on name servers ns1.teodns.com and ns2.teodns.com and is protected by a Let’s Encrypt YR2 TLS certificate, indicating a recent acquisition of a valid certificate for encrypted traffic. Registration was performed via Name.com, Inc., and the domain appears in a single AlienVault OTX pulse, suggesting that it has already been flagged by the threat‑intel community. VirusTotal records indicate that the site has been scanned by 91 security vendors, with no current detections, but the absence of alerts does not confirm safety. The infrastructure—public DNS, standard TLS, and a generic .dev TLD—fits a pattern used by actors deploying generic phishing sites to harvest credentials or deliver malicious payloads. Uncertainty remains regarding the specific target brand or the content served, as no page title, brand reference, or phishing kit details have been disclosed. Defenders should monitor DNS resolution for ruiheng.dev, block network connections to the associated IP address, and add the domain to URL filtering lists. Continuous threat‑intel feed correlation is recommended to detect any emergence of malicious payloads or credential‑harvesting pages linked to this infrastructure.

## EVIDENCE HASHES
----------------------------------------------------------------
PhishDestroy Case ID:  PD-20260717-D378E2
TLS cert SHA-256:      4aa1b6701f1c4f6ed2fb9626796adaa70fc86b7838c6b468cad580a4eca210e4

## 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.
