o365-support[.]com

The domain o365-support.com was taken offline as of the reporting date, July 23, 2026, after being intercepted by the PhishDestroy takedown service. Registration records show the domain was created on November 18, 2025 through GoDaddy.com, LLC and is delegated to the GoDaddy‑controlled name servers ns37.domaincontrol.com and ns38.domaincontrol.com. DNS resolution points to the IPv4 address 16.16.99.255, which belongs to Amazon.com, Inc. (AS16509) and is geolocated to Sweden. No TLS certificate is presented for the host, indicating that HTTPS connections are not available.

The site presented the page title “Sign in to your account,” and the intelligence feed classifies the activity as a Tech Support Scam that impersonates Microsoft. The domain appears on a single security blocklist, and the PhishDestroy block indicates active mitigation. Threat intelligence aggregation shows the domain referenced in fifteen AlienVault OTX pulses, reflecting ongoing analyst interest. VirusTotal analysis returned sixteen positive detections out of ninety‑five scanning engines, reinforcing the malicious classification.

From the available evidence, the infrastructure suggests a low‑cost hosting arrangement typical of opportunistic brand‑impersonation campaigns. The lack of an SSL certificate, combined with the use of a generic Microsoft‑related page title, aligns with the observed tech‑support narrative. Defenders should continue to block the domain at network perimeter devices, update URL filtering lists with the observed indicator, and monitor the associated IP range for any reappearance of similar payloads. Because the domain is already offline, incident response teams can focus on removing any residual references from internal logs and ensuring that end‑user awareness campaigns reference the specific page title and impersonated brand to reduce click‑through risk.
