t-mobile[.]yfeir[.]cc

Analysis of the domain t-mobile.yfeir.cc confirms it as an active phishing site targeting T-Mobile customers, classified under the Airdrop Scam kit. The domain was registered on February 21, 2026, through Gname.com Pte. Ltd., a registrar frequently associated with high-risk domains. It currently resolves to IP address 172.67.219.202, hosted on Cloudflare's infrastructure (AS13335) in the United States. Nameservers matiass.ns.cloudflare.com and paige.ns.cloudflare.com further indicate Cloudflare's role in the domain's hosting and DNS management, a common tactic to obscure origin and evade takedowns. Detection metrics reveal limited but concerning visibility: the domain appears on one security blocklist (PhishDestroy), and 15 of 93 security vendors on VirusTotal flag it as malicious.

Gridinsoft assigns a trust score of 0/100, reinforcing its high-risk classification. The HTTP status returns 200, suggesting the server is operational, though the page title 'yfeir.cc | 522: Connection timed out' may indicate intermittent availability or deliberate obfuscation. The SSL certificate, issued by Google Trust Services (WE1), is valid but does not mitigate the domain's malicious intent. Technologies detected include Cloudflare and HTTP/3, consistent with modern phishing infrastructure designed for resilience and performance.

The domain's registration age (five months) and continued activity suggest ongoing use in campaigns, though the exact scale and victim count remain unconfirmed. Defenders should prioritize blocking the domain and its resolving IP at network and endpoint levels. Monitoring for related subdomains or newly registered domains under the same registrar (Gname.com Pte. Ltd.) may help preempt further abuse. Given the brand impersonation of T-Mobile and the use of an Airdrop Scam kit, user education on recognizing such scams is recommended, particularly for customers of the targeted brand.
