threshold[.]airdrpsalerts[.]click

Analysis of threshold.airdrpsalerts.click indicates a high‑confidence brand‑impersonation campaign targeting Google users. The domain was registered on 2025-11-04 through Dynadot LLC and resolves to the IP address 216.58.206.36, which belongs to AS15169 Google LLC and is geolocated in Germany. Despite pointing to a legitimate Google infrastructure, the domain is not served over HTTPS; no SSL certificate was observed. The authoritative nameservers are brenna.ns.cloudflare.com and hassan.ns.cloudflare.com, both belonging to Cloudflare’s DNS service, a common choice for malicious operators seeking rapid deployment and resilience.

The page title returned by the HTTP response is simply "Google", matching the declared brand target. VirusTotal analysis shows that 16 of 95 security vendors have flagged the domain, reinforcing the suspicion of malicious intent. Independent assessments assign a Gridinsoft trust score of 0 / 100, and the domain appears on at least one public blocklist, where it has been listed by PhishDestroy. The overall risk rating is elevated, and the current operational status is offline, suggesting the site may have been taken down or is temporarily inaccessible.

Defenders should block any DNS resolution to this domain, enforce HTTPS‑only policies, and monitor outbound traffic for connections to 216.58.206.36 that originate from internal hosts, especially if such traffic is unexpected. Because the domain mimics a legitimate Google service, users should be reminded to verify URL authenticity and to avoid entering credentials on sites lacking a valid TLS certificate. Ongoing surveillance of the associated IP and the Cloudflare nameservers is recommended to detect potential re‑use of the infrastructure for future impersonation attempts.
