t-mobile[.]kozbj[.]cc

Analysis indicates that t-mobile.kozbj.cc was configured as a brand impersonation domain designed to resemble or exploit trust associated with a recognized telecommunications brand. Such domains are commonly used to attract visitors through misleading links, imitation login pages, account verification prompts, or other social-engineering techniques intended to collect credentials or personal information. At the time of assessment, the site was offline and no active content was available. The observed page title was "kozbj.cc | 522: Connection timed out," suggesting the infrastructure was no longer serving its intended content when reviewed.

Technical indicators provide multiple reasons for caution. The domain is flagged by 18 of 95 security vendors on VirusTotal. Registration records show the domain was created on February 21, 2026 and registered through Gname.com Pte. Ltd. Infrastructure analysis reveals resolution to IP address 172.67.136.84, located in the United States within AS13335 Cloudflare, Inc. network space. The domain appears on 1 security blocklist and has been blocked by PhishDestroy. No SSL certificate was identified during assessment. Combined with the impersonation theme and security detections, these indicators support classification as a malicious brand impersonation asset rather than a legitimate service endpoint.

Although the domain has been taken offline, residual risk remains because similar campaigns frequently migrate to newly registered domains with comparable naming patterns. Any user who previously visited the site should review account activity associated with services that may have been imitated, change passwords if credentials were entered, enable multi-factor authentication where available, and monitor for unauthorized access attempts. Security teams should retain indicators including the domain name, IP address 172.67.136.84, creation date February 21, 2026, and associated registration details for future detection and threat-hunting activities. Continued monitoring for related infrastructure and lookalike domains is recommended to identify possible campaign reappearance.
