“users-chain.com | 504: Gateway time-out”
Resumo das evidências
The domain users-chain.com was registered on February 23, 2026 through Dynadot LLC and is currently taken offline. DNS resolution points to the Cloudflare address 104.21.1.49, which belongs to AS13335 Cloudflare, Inc. and is geolocated in the United States. The authoritative nameservers are miles.ns.cloudflare.com and stephane.ns.cloudflare.com, confirming that the infrastructure is hosted behind Cloudflare’s reverse‑proxy service. HTTP probing returned a 404 status code while the page title presented by the server reads "users-chain.com | 504: Gateway time-out," indicating that the site is not serving legitimate content at the time of observation.
The SSL certificate is issued by Let’s Encrypt (identifier E7), which is typical for short‑lived malicious sites. Traffic is served over HTTP/3, a feature commonly leveraged by threat actors to improve performance and evade some legacy detections. The domain appears on four independent blocklists—PhishDestroy, MetaMask, ScamSniffer, and SEAL—demonstrating cross‑community consensus that it is being used for phishing. VirusTotal analysis shows three of ninety‑three scanning engines flag the host, providing additional vendor corroboration.
No specific brand or credential‑capture page has been identified in the available artifacts, and the page title does not reveal a targeted service. Defenders should continue to block the domain at perimeter and DNS layers, monitor for any resurrection of the host, and consider adding the IP address 104.21.1.49 to reputation‑based deny lists. Ongoing observation of the associated Cloudflare edge IPs is advised, as the infrastructure could be repurposed for future phishing campaigns.
