suite[.]tem3[.]io

The domain suite.tem3.io was registered on August 2, 2024 through GoDaddy.com, LLC and is currently resolved to the IPv6 address 2606:4700:3030::6815:7001, which belongs to AS13335 Cloudflare, Inc. in the United States. The site presents a TLS certificate issued by Google Trust Services under the WE1 root, indicating a valid HTTPS endpoint. Examination of HTTP headers reveals that the server returns a 404 status code, and the page title reported by crawlers is “Trézor Suite (Official) | Desktop & Web Crypto® Management”, explicitly referencing the Trezor brand. The presence of a Trezor reference, combined with the classification of the campaign as a crypto‑scam and the label “brand impersonation”, indicates that the infrastructure was intended to masquerade as an official Trezor management portal.

Static analysis of the front‑end stack shows the use of Node.js, React, Next.js, Webpack, and Cloudflare Browser Insights, all delivered over HTTP/3. The domain is listed on a single security blocklist and is actively blocked by PhishDestroy. VirusTotal scans have generated detections from 17 of 95 security vendors, reinforcing the malicious reputation. Nameservers val.ns.cloudflare.com and justin.ns.cloudflare.com confirm that the domain is fully delegated to Cloudflare's DNS service.

Because the site currently returns a 404 response, no definitive content such as login forms or malicious payloads has been captured, leaving the exact delivery mechanism uncertain. However, the combination of a legitimate‑looking TLS certificate, brand‑specific page title, and the observed technology stack strongly suggests a phishing‑oriented infrastructure designed to lure Trezor users into providing credentials or cryptocurrency credentials. Defenders should prioritize adding suite.tem3.io to network blocklists, enforce DNS sink‑hole rules for the associated IPv6 address, and educate end users that any unsolicited Trezor‑related portal should be verified against official URLs.
