INTELLIGENCE BRIEFING
Target: 52.228.161.161/32
Date: 2026-09-21
Target Identification
The address belongs to Microsoft Corporation (ASN 8075, Netname: MSFT) within the 52.224.0.0/11 CIDR block. Infrastructure classification identified the network role as Microsoft Azure CloudCompute.
Threat Assessment
Current reputation status was Low Risk with a risk score of 25. The profile flagged the host as a "Suspicious Host" despite zero blacklist hits and no active threat campaigns. Behavioral analysis recorded no honeypot hits, enumeration strikes, or WAF violations. However, signal contradictions were present, specifically regarding geolocation data.
Technical Observations
* Services: Ports 80 (HTTP) and 443 (HTTPS) were open. The server banner identified "Microsoft-Azure-Application-Gateway/v2".
* TLS: Certificates issued for smartscreen.microsoft.com were present.
* Fingerprint: HTTP/2 was enabled. A 502 status code was observed during probing.
* Geolocation: Reports listed Des Moines, IA, USA; however, RTT measurements (46ms) contradicted the claimed distance (7066km), marking the geolocation as physically implausible.
* DNS Hygiene: DNS hygiene scored Fair (40). SPF and DMARC records were present.
Recommendation
Analysis recommended monitoring the address with low severity. The decision was based on the presence of signal contradictions and insufficient data to classify specific intent. No firewall rules were required.
