massgravs.com was registered through Hostinger operations UAB on 29 January 2025 and uses the freednsdedi.com name servers ns1.freednsdedi.com and ns2.freednsdedi.com. The site resolves to 185.255.122.94, an address owned by Virtual Systems LLC in Ukraine (ASN 30860). No TLS certificate is presented, indicating the service is delivered over plain HTTP. The page title returned from the host is “Ativação do Microsoft Office”, and the domain is classified as a Microsoft brand impersonation used in a tech‑support scam.

Threat intelligence shows that 13 of 95 VirusTotal scanners have flagged the domain, and it appears on at least one public blocklist, with PhishDestroy already blocking it. Gridinsoft assigns a trust score of 0 out of 100, reinforcing the malicious assessment. The domain is currently offline, which limits immediate exposure but does not remove the risk of future re‑activation. Analysts should monitor the authoritative name servers for any changes, and add the IP address and domain to internal blocklists.

Network defenders are advised to enforce outbound filtering for HTTP traffic to the listed IP, and to update web‑gateway signatures to detect the “Ativação do Microsoft Office” title. Because the underlying infrastructure is hosted in Ukraine, any relocation of the service may involve different IP ranges, so continuous DNS and IP reputation checks are recommended. The lack of SSL and the low trust score suggest a low‑cost operation, yet the targeting of Microsoft users warrants heightened vigilance.
