## TLS CERTIFICATE
----------------------------------------------------------------

## 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: 2026-02-21 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration)
First detected:    2026-02-26 23:23:49 UTC (by PhishDestroy tracker)
Last verified:     2026-05-16 21:15:33 UTC
Current status:    taken down (registrar suspended or DNS dead)

## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-03-03 15:29:34 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.]

PhishDestroy identifies justback.io as a medium-risk phishing domain involved in generic social engineering attacks. Users are advised to exercise caution as the site attempts to deceive victims into divulging sensitive information.

The domain was registered on February 21, 2026, and is currently flagged by multiple security services including Google Safe Browsing for social engineering. It appears on one security blocklist and is detected by 9 out of 95 VirusTotal vendors.

At present, justback.io has been taken offline, reducing immediate risk. Users and organizations should maintain vigilance and ensure phishing filters are up to date to prevent future exposures.

## EVIDENCE HASHES
----------------------------------------------------------------
TLS cert SHA-256:      943eb9996d090225a601777de2f5314bfe70a9da8b2eaf2f6a4c15c672a2edef

## 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.
