qusi.fr: Confirmed Phishing Site

On July 28, 2026, the domain qusi.fr is confirmed to be a phishing site. This domain has been registered through KEY-SYSTEMS GmbH and is currently active. The HTTP status of the domain is 200, indicating that the site is accessible and operational.

The domain appears on one security blocklist, specifically PhishDestroy, which has flagged it as a known phishing site. The nameservers for qusi.fr are ns1.abovedomains.com, ns2.abovedomains.com, ns3.abovedomains.com, and ns4.abovedomains.com, suggesting a standard nameserver configuration. While the domain has been scanned by 91 vendors on VirusTotal, none currently flag it as malicious.

However, the absence of detections does not guarantee the domain's safety, as phishing sites can often evade initial detection. Defenders should exercise caution and consider blocking this domain to prevent potential phishing attacks. The exact content and purpose of the site have not been fully analyzed, but given its presence on a security blocklist and active status, it is advisable to treat qusi.fr as a confirmed phishing site until further evidence is available.

## EVIDENCE HASHES
----------------------------------------------------------------
Favicon MD5:       7e840862161341271697daa99a40d76b
TLS cert SHA-256:      31d4b7e3e170ae9df564b92f95feb6d121cc427a1dc017f18cede39a804b37c6

## 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.
