poloniexchain[.]com

Analysis of poloniexchain.com shows a recent domain registration (created 2025-09-07) by Gname.com Pte. Ltd. The domain resolves to 172.67.215.59, an address owned by Cloudflare, Inc. (AS13335) and is served through Cloudflare's network, indicated by the presence of Cloudflare nameservers (aria.ns.cloudflare.com, arturo.ns.cloudflare.com) and detection of Cloudflare-specific technologies such as HTTP/3, HSTS, and Cloudflare Browser Insights. The TLS certificate is issued by Google Trust Services under the WE1 root, confirming that the site presented a valid HTTPS connection at the time of observation. Google Safe Browsing classified the site as a social engineering threat, and one of ninety-five VirusTotal scanners flagged it, reinforcing the suspicion of malicious intent.

The domain is listed on a single security blocklist and has been actively blocked by the PhishDestroy mitigation service, suggesting that downstream security products are already enforcing protection. The primary malicious behavior is the impersonation of the dYdX brand, as indicated in the intelligence feed; no additional content, page title, or visual analysis is available because the site has been taken offline. Uncertainty remains regarding the specific phishing kit or payload used, and no payload hashes or URL paths have been disclosed.

Defenders should add 172.67.215.59 and poloniexchain.com to deny-list rules, monitor for new domains registered by the same registrar within the same period, and enable real-time Safe Browsing or similar URL filtering to capture future dYdX-related impersonation attempts. Continuous observation of Cloudflare-hosted infrastructure may reveal reuse of the same IP range for related campaigns.
