## INFRASTRUCTURE
----------------------------------------------------------------
IP address:      216.198.79.1 (US, Walnut)
ASN:             ASAS16509 Amazon.com, Inc.
Hosting org:     AS16509 Amazon.com, Inc.
Registrar:       Name.com, Inc
Nameservers:     ns1.vercel-dns.com, ns2.vercel-dns.com
Registered:      2026-02-21
Expires:         2027-02-16
Page title:      Coinbase Support

## TLS CERTIFICATE
----------------------------------------------------------------
Issuer:     none
Status:     INVALID chain

## 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:    2026-02-25 02:39:27 UTC (by PhishDestroy tracker)
Earliest abuse rec: 2026-02-16 13:39:23 UTC — PREDATES current WHOIS registration; retained from a previous registration cycle of the same domain name
Last verified:     2026-05-31 13:20:39 UTC
Neutralised:       2026-02-23 03:15:03 UTC
Current status:    taken down (registrar suspended or DNS dead)

Note: one or more events above predate the WHOIS creation date. This typically means
the same domain name was previously registered, detected, dropped, and then re-registered
by a new party. PhishDestroy preserves the full historical record for operator-attribution
research even when the underlying infrastructure changes hands.

## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-03-03 00:25:54 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.]

PhishDestroy identifies base.assist-us.xyz as a high-risk phishing domain pretending to be Coinbase. This site aims to deceive users by appearing as official Coinbase Support, tricking visitors into revealing sensitive data.

This phishing works by mimicking Coinbase’s branding and interface to convince users they are on a legitimate site. Users may be asked for login credentials or personal information, which attackers then capture for fraudulent use.

If you visited base.assist-us.xyz, immediately change your Coinbase password and enable two-factor authentication. Avoid clicking links from unknown sources and report suspicious sites to help protect others.

## EVIDENCE HASHES

PhishDestroy Case ID:  PD-20260216-95DC3F

## 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.
