smartdefi[.]cyou

Analysis of smartdefi.cyou indicates that the domain was registered on 21 February 2026 and is presently taken offline. DNS resolution points to the address 104.21.16.1, which belongs to Cloudflare’s network (AS13335) and is geolocated in the United States. The site presented the page title “Defi‑ETH”, matching the declared scam type of a crypto drainer. The TLS certificate is issued by Cloudflare TLS Issuing ECC CA 1, confirming the use of Cloudflare’s edge‑termination service.

Reputation data shows the domain appears on a single security blocklist and is listed as blocked by PhishDestroy. Gridinsoft assigned a trust score of 0 out of 100, reflecting a high confidence of malicious intent. VirusTotal scans returned 7 detections out of 95 security vendors, reinforcing the suspicion.

No additional evidence such as phishing kit fingerprints, redirect chains, or malicious payloads has been published, and the page content has not been captured because the site is offline. Defenders should continue to block the domain at perimeter devices, monitor for any re‑registration of the same name or similar sub‑domains, and add the associated IP address to deny lists. Ongoing observation of Cloudflare‑hosted IP ranges for similar activity is recommended, as the infrastructure can be reused for future campaigns.
