auth[.]mobillvers[.]top

The domain auth.mobillvers.top was observed hosting a page whose title is "Sign In" and that claims to impersonate the Steam service. The domain was registered on 22 December 2025 through Web Commerce Communications Limited and is serviced by Cloudflare, as indicated by the authoritative nameservers guss.ns.cloudflare.com and ines.ns.cloudflare.com and by the resolved address 172.67.158.85, which belongs to AS13335 Cloudflare, Inc., located in the United States. No TLS certificate is presented, meaning the site operates without HTTPS protection. Analysis of public threat‑intel sources shows that 16 of 93 security vendors on VirusTotal flagged the domain, and Google Safe Browsing categorises it as a social‑engineering site.

The domain is listed on a single security blocklist and has been blocked by the PhishDestroy service. Gridinsoft assigns a trust score of 0 out of 100, reflecting a high likelihood of malicious intent. The listed scam type is a gaming scam, consistent with the Steam impersonation claim. The current status is offline, which limits further live probing, and no HTTP response details are available beyond the page title.

Consequently, the exact content and any credential‑harvesting mechanisms remain unverified. Defenders should continue to block the domain at network perimeter and DNS layers, monitor for any resurgence of the host or related sub‑domains, and apply URL filtering rules that capture the observed page title and the identified brand target. Additional surveillance of the Cloudflare IP range for new domains registered by the same registrar may help uncover future campaigns that reuse this infrastructure.
