Intellective Briefing: 52.217.87.144

**Target Identification and Ownership**

The host address 52.217.87.144/32 is associated with Amazon Web Services (AWS) under the routing operator AMAZON-02. The network block 52.192.0.0/12 is registered to Amazon Technologies Inc. (NetName: AT-88-Z) within the ARIN region. Geolocation data places the approximate network location in Ashburn, Virginia, United States.

**Infrastructure and Role**

Network role analysis identifies the infrastructure as a Web Server hosted within the United States. Observations indicate the host operates as part of the AWS provider ecosystem. Current assessments do not confirm the address as a CDN, VPN, proxy, Tor node, mobile, residential, or hosting service. The anycast status remains unverified.

**Security Posture and Hygiene**

DNS hygiene checks for SPF, DMARC, CAA, DNSSEC, and FCR-DNS were not assessed, resulting in a zero score and a "Not assessed" label. The absence of these checks does not establish a lack of security controls. No bogon status or residential/mobile characteristics were detected.

**TLS and Certificate Observations**

A TLS probe returned a historical certificate for the subject CN=s3.amazonaws.com. The certificate, issued by "CN=Amazon RSA 2048 M01, O=Amazon, C=US," covers the S3 service endpoints including s3.amazonaws.com and various regional access points for us-east-1. The validity period spans from September 20, 2026, to April 5, 2027. The probe status is marked as unknown, and the certificate is flagged as stale, indicating the probe did not retrieve a live certificate or the target does not respond to TLS handshakes at the probed moment.

**Risk Assessment**

The calculated risk score is zero. However, this metric reflects the absence of detected malicious indicators or failed probes rather than a definitive confirmation of benign activity. The limited scope of DNS hygiene checks and the stale TLS probe result in inconclusive evidence regarding active service validation.

**Recommendation**

Given the association with a major cloud provider and the lack of conflicting malicious indicators, the address presents a standard risk profile for AWS infrastructure. Continued monitoring is recommended to corroborate service activity, particularly in light of the stale TLS probe results and unverified anycast status.
