## ABUSE-REPORT HISTORY (evidence of registrar non-response)
----------------------------------------------------------------
Status: CLOSED — no report required.
This domain was neutralised before the abuse-report cycle could be dispatched — either
the hosting provider / registrar suspended it on their own, the DNS went dead, or the
operator abandoned the infrastructure. PhishDestroy keeps the evidence bundle on file
for audit but no formal notice was sent.

## TIMELINE
----------------------------------------------------------------
Domain registered: 2026-05-06 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration)
First detected:    2026-05-06 22:54:00 UTC (by PhishDestroy tracker)
Last verified:     2026-06-07 02:33:38 UTC
Neutralised:       2026-05-12 00:01:13 UTC
Current status:    taken down (registrar suspended or DNS dead)

## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-05-06 22:55:29 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.]

PhishDestroy identifies captcha-security.biz as an active fake CAPTCHA phishing domain registered through PDR Ltd. d/b/a PublicDomainRegistry.com on May 06, 2026. This impostor mimics legitimate CAPTCHA services to harvest user credentials and session tokens, deploying a drainer kit hosted on IP 188.114.96.3. The domain’s SSL certificate issued by Let’s Encrypt lends false legitimacy, while its recent creation date and fraudulent branding aim to deceive users into surrendering sensitive login data.  This domain was flagged by 3 of 95 VirusTotal security vendors and appears on 1 public blocklist, including the Open Information Security Database (OISD). Its technical indicators include a Let’s Encrypt SSL certificate, registration via PDR Ltd., and resolution to IP 188.114.96.3. The deceptive domain was created on May 06, 2026, and currently remains unblocked by major browsers and services despite its elevated phishing risk.  As of this report, captcha-security.biz is active and poses an elevated threat. Immediate response includes blocking the domain at the network and DNS levels, revoking the SSL certificate via Let’s Encrypt, and updating browser-based phishing filters. The remaining risk remains elevated due to the domain’s recent registration and active hosting infrastructure.

## EVIDENCE HASHES
----------------------------------------------------------------
Favicon MD5:       16a75c7824b5223b8e22864354e9e33f
TLS cert SHA-256:      cdda7295157beb0a07b364d5e701595949d385863de55f1343cc537f39c0ee3f

## 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 (volunteer 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.
