This domain is flagged as an active credential harvesting phishing site designed to mimic legitimate authentication portals. Analysis indicates a high-risk classification due to its targeted infrastructure and confirmed malicious activity, including the interception of user credentials and session tokens. Infrastructure analysis reveals the domain microsaft.co was registered on May 23, 2026, and currently resolves to the IP address 13.248.169.48, hosted on AWS Global Accelerator infrastructure. Security vendor detection on VirusTotal shows 1 out of 95 engines flagging the domain as malicious. The domain appears on three security blocklists and is actively blocked by multiple threat intelligence feeds. The SSL certificate is issued by GoDaddy.com, using the intermediate CA GoDaddy TLS Intermediate CA DV - R1v1, which does not correlate with the expected certificate chain of the imitated service. Mitigation against this threat requires immediate action from network security teams. Block the domain microsaft.co and its resolving IP 13.248.169.48 at the perimeter firewall and DNS filtering layers. Deploy endpoint protection rules to detect and prevent access to the domain, particularly on devices handling sensitive authentication workflows. Monitor for indicators of compromise, including unexpected authentication attempts or anomalous session activity originating from internal networks. Security teams should also review logs for connections to the domain or IP within the last 30 days to identify potential exposure. User awareness training should emphasize the risks of credential harvesting sites, particularly those impersonating login portals with slight domain misspellings.
