auth-dydx-exchangee-io-us[.]pages[.]dev

Analysis of auth-dydx-exchangee-io-us.pages.dev indicates a high-risk brand impersonation attempt targeting dYdX, a cryptocurrency exchange. The domain, registered on February 21, 2026, through Cloudflare, Inc., was flagged by 10 of 95 security vendors on VirusTotal, though no detailed scan artifacts are available for review. Google Safe Browsing classified the site as engaging in social engineering, and it appears on at least one security blocklist. The domain resolved to IP 172.66.47.115 (AS13335, Cloudflare, Inc., US) and employed Cloudflare nameservers (malcolm.ns.cloudflare.com, olivia.ns.cloudflare.com).

HTTP requests returned a 403 status, and the page title was explicitly labeled 'Suspected phishing site | Cloudflare,' confirming its detection and takedown by the hosting provider. SSL certification was issued by Google Trust Services (WE1), a common practice for both legitimate and malicious Cloudflare-hosted domains. Infrastructure analysis reveals the use of HSTS, a security feature often leveraged to lend credibility to phishing sites. The domain is currently offline, likely due to enforcement actions by Cloudflare or security vendors.

Defenders should treat this domain as confirmed malicious and prioritize blocking it at the DNS and network levels. Historical logs should be reviewed for connections to 172.66.47.115 or interactions with the domain prior to takedown. Given the targeting of cryptocurrency users, wallet addresses or transaction patterns associated with this campaign should be cross-referenced with known dYdX phishing clusters. No evidence of a specific phishing kit or payload delivery was identified in the available data.
