t-mobile[.]zfeor[.]cc

Analysis of t-mobile.zfeor.cc shows a brand‑impersonation infrastructure that was active during early 2026. The domain was registered on February 21 2026 via Gname.com Pte. Ltd. and is hosted on Cloudflare’s network (ASN 13335) in the United States, resolving to 104.21.77.181. DNS resolution points to the Cloudflare authoritative nameservers matias.ns.cloudflare.com and paige.ns.cloudflare.com, and the site served over HTTP/3, indicating a modern CDN configuration. The TLS certificate presented is issued by Google Trust Services under the WE1 root, confirming a valid HTTPS endpoint despite the site returning a 522 “Connection timed out” page title.

Security‑vendor scanning on VirusTotal recorded 13 positive detections out of 93 scanners, and the domain is listed on a single external blocklist. Independent threat‑intel feeds (PhishDestroy) have already taken the site offline, and the Gridinsoft trust score is 0 / 100, reflecting an extremely low reputation. The observed phishing kit is labeled “Airdrop Scam,” and the domain explicitly impersonates the t‑mobile brand.

No additional content was captured, so the exact payload or credential‑harvesting pages remain unknown. Defenders should immediately block the IPv4 address 104.21.77.181 and the domain t-mobile.zfeor.cc at perimeter and endpoint layers, enforce URL filtering for Cloudflare‑hosted domains that resolve to the same ASN, and monitor for any re‑registration attempts. Continued observation of the associated nameservers and certificate fingerprint is advised to detect potential re‑use of the infrastructure for new impersonation campaigns.
