dydx-exchangee-eng-us[.]pages[.]dev

Analysis of dydx-exchangee-eng-us.pages.dev indicates a confirmed brand‑impersonation campaign targeting the dYdX cryptocurrency exchange. The domain was registered on 2026-02-21 through Cloudflare, Inc. and resolves to the IP address 172.66.44.213, which belongs to AS13335 Cloudflare, Inc., located in the United States. DNS resolution uses the Cloudflare authoritative nameservers peaches.ns.cloudflare.com and gordon.ns.cloudflare.com, confirming the hosting provider. The site presents a TLS certificate issued by Google Trust Services under the WE1 intermediate, suggesting a valid HTTPS connection despite the malicious intent. HTTP response codes return 403, indicating the site is currently offline or blocked.

Technical fingerprints show the presence of HSTS, Cloudflare, and HTTP/3, all typical of Cloudflare‑hosted services. A Gridinsoft trust score of 0 / 100 flags the domain as highly untrusted. The page title, "dYdX Exchange – Decentralized Crypto Trading Platform," directly mirrors the legitimate dYdX branding, reinforcing the impersonation narrative. Security controls have already taken action: PhishDestroy lists the domain as blocked, and it appears on one external security blocklist.

VirusTotal scanning reports five of ninety‑three vendors flagging the domain, providing independent corroboration of malicious behavior. The campaign is classified as wallet/seed phishing, aiming to harvest cryptocurrency wallet credentials or seed phrases from unsuspecting users. Defenders should ensure the domain is added to outbound and inbound filtering rules, monitor Cloudflare‑hosted subdomains for similar naming patterns, and enforce strict TLS pinning for the legitimate dYdX site to prevent credential interception. Continuous threat‑intel feeds should be consulted for any resurgence of the domain or related indicators, and incident response teams should be alerted to potential credential theft attempts linked to this infrastructure.
