t-mobile[.]com-viodf[.]cc

Analysis indicates that the domain t-mobile.com-viodf.cc was registered on 21 February 2026 through Gname.com Pte. Ltd. and is currently taken offline. The site resolves to the Cloudflare‑owned address 188.114.96.3 (AS13335, United States) and was served via nginx with a default “Welcome to nginx!” title, suggesting no custom landing page was observed before takedown. The infrastructure uses Cloudflare nameservers dilbert.ns.cloudflare.com and riya.ns.cloudflare.com and supports HTTP/3, confirming the presence of a modern CDN front‑end. The SSL certificate presented is issued by Google Trust Services under the WE1 hierarchy, indicating a valid TLS chain despite the malicious intent.

The domain is classified as a brand‑impersonation campaign targeting the x.com brand. Gridinsoft assigned a trust score of 0/100, and the domain appears on one external blocklist. PhishDestroy has already blocked the domain, and VirusTotal reports that 20 of 93 scanned security vendors flagged the host as malicious, reinforcing the suspicion of abuse. At present no artifacts such as phishing email samples, credential‑harvesting URLs, or malicious payload hashes have been released, so the operational scope cannot be fully quantified.

Defenders should immediately add t-mobile.com-viodf.cc to network and email filtering rules, enforce DNS‑based blocking, and monitor traffic to the associated IP 188.114.96.3 for any residual activity. Because the domain leveraged a legitimate SSL certificate and Cloudflare’s CDN, it may have been used to host short‑lived credential‑harvesting pages that are no longer reachable; continuous observation of the IP range and related sub‑domains is advised. Organizations should also review recent login attempts to x.com from the IP range and consider enforcing multi‑factor authentication for accounts that may have been targeted.
