Analysis indicates that the domain rbxcorp.net was registered on 21 February 2026 through NiceNIC International Group Co., Limited. The domain resolves to the IP address 188.114.96.3, which belongs to Cloudflare, Inc. (AS13335) and is located in the United States. The hosting infrastructure is protected by Cloudflare, as evidenced by the presence of the nameservers emily.ns.cloudflare.com and jobs.ns.cloudflare.com, and the use of HTTP/3. An HTTP 403 response is returned for the root request, and the page title reported by scanners is “Just a moment…”. The TLS certificate is issued by Google Trust Services under the WE1 identifier, confirming the use of a legitimate certificate authority.

Reputation data shows the domain appears on a single security blocklist and has been blocked by the PhishDestroy service. On VirusTotal, six of ninety‑three scanners flagged the domain, contributing to a low Gridinsoft trust score of 6 out of 100. The overall risk rating assigned by the reporting system is high, and the campaign status remains active as of the report date, 23 July 2026. The evidence points to a generic phishing operation, but the specific payload or target brand has not been disclosed by the available intelligence. Consequently, the exact phishing vector and victim profile remain uncertain.

Defenders should add rbxcorp.net to blocklists, enforce DNS filtering, and monitor outbound connections to the associated Cloudflare IP range. Network sensors should flag any HTTP 403 responses that include the “Just a moment…” title from this domain. Continuous re‑scanning with VirusTotal and other multi‑engine services is recommended to capture any changes in detection counts. Organizations using web filtering solutions should ensure the domain is denied, and incident response teams should be prepared to investigate any user reports that reference this domain.
