authg[.]rustomega[.]net
“Sign In”
Résumé des preuves
The domain authg.rustomega.net was registered on November 16, 2025 through Web Commerce Communications Limited and is currently taken offline. Infrastructure analysis shows the domain resolves to IP address 185.178.208.158, which belongs to AS57724 DDOS-GUARD LTD located in Russia. Both authoritative nameservers, ns1.ddos-guard.net and ns2.ddos-guard.net, are hosted by the same provider, indicating a single‑point hosting arrangement typical of fast‑flux or low‑cost hosting services. No TLS certificate was observed, meaning the site would have been served over plain HTTP, a common characteristic of credential‑harvesting pages.
The page title returned by the server was "Sign In," matching the brand impersonation of Steam indicated in the intelligence. VirusTotal scanned the domain with 95 engines and recorded nine detections, reflecting moderate detection by security products. Google Safe Browsing classified the URL as social engineering, and the domain appears on one external blocklist, confirming it has been flagged by at least one threat‑intelligence source. The domain was blocked by PhishDestroy, which further corroborates its malicious intent.
While the exact payload or credential‑capture mechanism remains unverified, the combination of brand impersonation, lack of encryption, and multiple security vendor flags provides sufficient evidence to treat the domain as a high‑confidence malicious indicator. Defenders should add the domain and its resolving IP to blocklists, monitor DNS queries for the associated nameservers, and enforce network controls that prevent connections to the IP address. Continuous re‑evaluation is advised in case the infrastructure reappears or is reused for additional campaigns.
