rbtc-tangub[.]com

The domain rbtc-tangub.com was registered on July 20, 2026 through NICENIC INTERNATIONAL GROUP CO., LIMITED and is currently resolving to the IP address 172.67.135.214. Its authoritative name servers are aaron.ns.cloudflare.com and bailey.ns.cloudflare.com, indicating that the domain is hosted on the Cloudflare network. The domain appears on a single security blocklist and has been explicitly blocked by the PhishDestroy service, confirming that it is being treated as a phishing source.

VirusTotal records show that the domain was scanned by 91 security vendors; none of the scanners reported a detection at the time of analysis, but the absence of detections does not constitute proof of benign behavior. The limited blocklist presence and the recent creation date suggest a short operational window, typical of fast‑flux phishing campaigns that rely on rapid deployment and takedown before widespread mitigation. Infrastructure analysis reveals no additional IPs or hosting services beyond the single Cloudflare‑assigned address, and no anomalous ASN information is available.

Current public intelligence does not provide details on the page content, SSL certificate specifics, or the exact phishing lure employed, leaving the payload and targeted brand ambiguous. Defenders should continue to monitor the domain for any changes in detection status, add the IP and domain to local blocklists, and enforce outbound filtering to prevent credential submission to the observed host. Given the active status and recent creation, proactive containment, including DNS sinkholing and user education about unsolicited communications that reference this domain, is advised.
