IP Intelligence Briefing: 3.5.131.151/32
Risk Status: Low Risk (Score: 20)
Observation Date: 2026-09-07
The target address was identified as an Amazon Web Services infrastructure asset belonging to Amazon Data Services Northern Virginia (AS16509, AMAZON-S3). Geolocation data placed the system in Columbus, OH, though validation flagged a contradiction where the claimed distance contradicted RTT physics measurements.
Network services exposed included HTTP (80), HTTPS (443), and HTTP-Alt (8080). Server banners identified the system as AmazonS3, with reverse DNS resolving to s3-website.us-east-2.amazonaws.com. TLS certificates were issued by Amazon RSA 2048 M01.
Threat indicators yielded no active attacks, known campaigns, or blacklist associations. The neighborhood classification was marked clean with zero threat siblings. The profile recommendation was to monitor due to signal contradictions present in the data.
