Analysis indicates that coinetextensionbase.gitbook.io is an active brand‑impersonation site targeting Coinbase users. The page title "Coinbase® Wallet Extension® - Getting Started: Wallet Extension | u" suggests it is masquerading as an official Coinbase wallet guide. The domain was registered on March 14, 2026 and resolves to 104.18.40.47, an IP owned by Cloudflare (AS13335) located in the United States. Infrastructure details show Cloudflare DNS (dahlia.ns.cloudflare.com, hugh.ns.cloudflare.com) and a Google Trust Services / WE1 SSL certificate, with HTTP status 307 and support for HTTP/3, HSTS, Google Cloud Trace, and GitBook. The site appears on three security blocklists and is blocked by PhishDestroy, MetaMask, and SEAL. VirusTotal reports 14 of 94 scanners flagging the domain, and Gridinsoft assigns a trust score of 0/100, reinforcing the high‑risk assessment. Defenders should immediately add the domain to outbound and inbound deny lists, enforce strict URL filtering for any Coinbase‑related traffic, and educate users to verify the correct Coinbase domain before entering credentials. Continuous monitoring of DNS queries for this host and related Cloudflare‑served IP ranges is advised to detect potential re‑use of the same infrastructure in future campaigns.
