improvxf.run Safety Check — Generic Phishing Detected

The domain improvxf.run is presently active and has been classified as a generic phishing site with a high risk rating. Registration records show the domain was acquired through MarkMonitor Inc., and its authoritative name servers are ns911a.microsoftinternetsafety.net and ns911b.microsoftinternetsafety.net. An HTTP request to the root URL returns a 302 redirect, indicating that the site is directing visitors to another location, a common technique used in phishing campaigns to obscure the final landing page.

The domain appears on a single security blocklist, PhishDestroy, which has already flagged it for malicious activity. VirusTotal analysis reveals that 20 out of 91 scanning vendors have identified the domain as malicious, providing additional corroboration of its phishing intent. No additional evidence such as SSL certificates, IP address attribution, or page title information is currently available in the intelligence set.

Defenders should block improvxf.run at the network perimeter and include it in web filtering policies. Continuous monitoring of the domain's resolution and any changes to its hosting infrastructure is advised, as the 302 redirect could be updated to point to new malicious resources. Organizations using threat intelligence feeds should ensure that the domain is marked as high‑risk and that any inbound traffic to it is denied or logged for further investigation.

## EVIDENCE HASHES
----------------------------------------------------------------
TLS cert SHA-256:      57827fa88083035e2381d11a25a7825f58138a6d1a4c8d389c6a9b841720f4bd

## 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.
