natwest[.]mobilesterms[.]com

Analysis of the domain natwest.mobilesterms.com shows a typical banking phishing infrastructure that was taken offline prior to this report. The domain was registered on March 11 2026 through NiceNIC International Group Co., Limited and resolves to the IP address 159.100.6.5, which is hosted in Germany under ASN 214036 (Ultahost, Inc.). The authoritative nameservers are ns3.my-ndns.com and ns4.my-ndns.com. No SSL certificate is present, and an HTTP request returns a 403 status code, indicating that the site is not serving content at the time of testing.

The page title, captured before takedown, reads "Login Step 1 - Online Banking," aligning with the declared scam type of Banking Phishing. Technical fingerprints identify LiteSpeed web server software and HTTP/3 support. The domain appears on a single security blocklist and has been flagged by five of ninety‑five VirusTotal scanners, confirming that multiple threat‑intelligence sources have observed malicious activity associated with the host. PhishDestroy has also blocked the domain.

While the site is currently offline, defenders should treat the observed indicators as high‑confidence evidence of credential‑stealing activity targeting NatWest customers. Recommendations include adding the domain and its IP address to deny‑list rules, monitoring for any future re‑registration of similar sub‑domains, and correlating logs for attempted connections to the listed nameservers or IP range. Further analysis is limited by the lack of live content, so continued observation of the hosting provider and associated infrastructure is advised to detect potential re‑use.
