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

The domain dydx-exchangee-en-us.pages.dev was created on October 14, 2025 and is currently taken offline. It resolves to the Cloudflare edge address 172.66.44.161, which is announced by AS13335 Cloudflare, Inc. and located in the United States. The site presents the page title "Suspected phishing site | Cloudflare", indicating that Cloudflare has flagged the content as suspicious. The domain is registered through Cloudflare, Inc., and the authoritative nameservers listed are lex.ns.cloudflare.com, ns.cloudflare.com, ns2.cloudflare.com, and rosalie.ns.cloudflare.com, all typical of Cloudflare‑hosted services. An SSL certificate issued by Google Trust Services under the WE1 authority secures the connection, and the site advertises HSTS and HTTP/3 support, consistent with modern Cloudflare deployments.

Security‑vendor scans on VirusTotal show that 12 of 95 scanners flagged the domain, and Google Safe Browsing classifies it as a social‑engineering threat. Gridinsoft assigns a trust score of 0 out of 100, and the domain appears on one public security blocklist. PhishDestroy has also blocked the host. An HTTP request to the site returns a 403 status code, which aligns with Cloudflare’s protective response for malicious content. The intelligence tags the activity as a crypto‑scam that impersonates the dYdX brand, confirming a targeted brand‑impersonation campaign.

While the technical indicators strongly suggest malicious intent, the exact payload or phishing page content has not been captured, leaving the specific user‑interaction vector unknown. Defenders should continue to block the domain at network perimeters, update URL filtering rules, and monitor for any re‑registration attempts. Given the Cloudflare hosting, any future iterations may reuse the same edge IP range, so broader Cloudflare‑based blocking may be warranted. Continuous re‑scanning on VirusTotal and other multi‑engine platforms is recommended to capture any changes in detection ratios.
