steamcuommunity[.]sbs

Analysis of steamcuommunity.sbs shows a newly registered domain (creation date February 21 2026) that has been actively used for a gaming‑related impersonation of the Steam brand. The domain resolves to IP 104.21.32.1, an address owned by AS13335 Cloudflare, Inc. and geolocated in the United States. Cloudflare hosting is common for legitimate services, but the specific IP appears in a security blocklist and is associated with malicious activity in this case. The site was flagged by PhishDestroy and listed on one public blocklist, indicating that at least one external sinkhole has taken action against it.

VirusTotal scans returned 12 detections out of 93 security vendors, demonstrating a moderate consensus among scanners that the domain hosts malicious content. Gridinsoft assigned a trust score of 0 / 100, reinforcing the suspicion of abuse. AlienVault OTX includes the domain in a single threat‑intel pulse, providing additional community‑sourced confirmation of its malicious nature. The SSL certificate is identified as “WE1,” which does not correspond to a recognized certificate authority and may be a self‑signed or otherwise low‑trust certificate.

The domain is currently offline, but the infrastructure—particularly the shared Cloudflare IP—could be reused for future impersonation campaigns. Defenders should immediately block steamcuommunity.sbs at DNS and proxy layers, add the associated IP address to network‑level deny lists, and monitor for any new subdomains or similar domains targeting the Steam brand. Continuous threat‑intel feeds should be consulted for updates to the blocklist status and any emerging indicators of compromise linked to the observed Cloudflare IP range.
