koin-basepro-logn[.]pages[.]dev

Analysis of the domain koin-basepro-logn.pages.dev indicates a high-risk phishing operation targeting Coinbase users, hosted on Cloudflare Pages infrastructure. The domain, registered on February 21, 2026, resolves to IP address 172.66.44.172 within Cloudflare's network (AS13335, United States). As of July 23, 2026, the domain returns an HTTP 403 status, and Cloudflare's interstitial page titles it 'Suspected phishing site,' confirming its detection and partial mitigation. The site appears on one security blocklist (PhishDestroy), and Google Safe Browsing flags it for social engineering.

Eleven of 93 security vendors on VirusTotal detect the domain as malicious, though the exact payload or phishing kit remains unconfirmed. SSL certificate data shows issuance by Google Trust Services (WE1), consistent with Cloudflare's managed certificates. Nameservers (hasslo.ns.cloudflare.com, jamie.ns.cloudflare.com) and registrar details further tie the domain to Cloudflare's ecosystem. Gridinsoft assigns a trust score of 0/100, reinforcing its classification as brand impersonation.

Defenders should treat this domain as compromised and block all resolutions at the DNS level. While the domain is currently offline, historical DNS records and certificate transparency logs should be reviewed for prior resolutions or subdomains. No evidence suggests lateral movement or additional C2 infrastructure, but monitoring for related domains using the same Cloudflare Pages pattern (e.g., *-logn.pages.dev) is recommended.
