## 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 23:22:12 UTC (by PhishDestroy tracker)
Last verified:     2026-04-13 13:11:36 UTC
Current status:    taken down (registrar suspended or DNS dead)

## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-03-24 00:53:36 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.]

PhishDestroy identifies join-alt5sigma.com as a domain associated with generic phishing activities. Classified under a low risk level, this domain was flagged due to suspicious behavior typical of phishing campaigns. Its creation date is notably set in the future (February 21, 2026), which could suggest data inconsistencies or an attempt to evade detection using manipulated domain registration details.

Technical indicators reveal that join-alt5sigma.com resolved to IP address 104.21.112.1 and was registered via MAT BAO CORPORATION. The domain appeared on two separate security blocklists, supporting the classification of potential malicious use. A VirusTotal scan showed only one out of 95 security vendors flagged the domain, indicating limited but present recognition of its threat. The landing page reported a "404 Not Found" status, which suggests the domain was either abandoned or taken down before delivering any payload or phishing content.

Currently, join-alt5sigma.com is offline, effectively neutralizing the threat it posed. PhishDestroy recommends maintaining vigilance and ensuring that no residual connections or cached links to the domain remain in use. Users and security professionals should continue monitoring related domains or IPs for any similar indicators to prevent future phishing incursions linked to this infrastructure.

## EVIDENCE HASHES
----------------------------------------------------------------
TLS cert SHA-256:      70520b2f9680088c4ae7d5f67b4b4f6279e32e395c6e78f753f2d75c1b17bf8a

## 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.
