## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-03-25 20:02:06 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-browser-extension.pages.dev as an active phishing domain designed to impersonate the Coinbase Wallet Extension, misleading users into believing they are accessing a legitimate Web3 service. Classified under generic phishing, this domain aims to harvest sensitive user credentials by exploiting trust in a well-known cryptocurrency brand. The page title "Coinbase Wallet Extension - Secure Web3 Access" attempts to reinforce legitimacy and lure unsuspecting victims.

Technical analysis reveals the domain resolves to IP address 172.66.47.49 and is registered through Cloudflare, Inc., a common infrastructure provider that can sometimes shield malicious actors. Despite being flagged by only 3 out of 95 security vendors on VirusTotal, the domain’s active status and deceptive naming convention underline its potential risk. Use of Cloudflare’s platform may complicate takedown efforts but also provides valuable attribution data.

Currently, base-browser-extension.pages.dev remains operational and poses a medium risk level. Users are strongly advised to refrain from interacting with this domain and to access cryptocurrency wallets exclusively via official channels. PhishDestroy continues to monitor the domain’s status and coordinates with cybersecurity partners to mitigate threats emerging from this fraudulent site, urging vigilance to prevent credential compromise in the evolving Web3 ecosystem.

## EVIDENCE HASHES
----------------------------------------------------------------
TLS cert SHA-256:      d69b953d0f1b022e9c26dea811c526a36762af1f5b3d947fc1732c57478b3138

## 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.
