3.135.70.52
IP 3.135.70.52 was identified as Amazon Web Services infrastructure under ASN 16509 within the 3.128.0.0/9 block. Reverse DNS resolution confirmed the address as `ec2-3-135-70-52.us-east-2.compute.amazonaws.com` serving HTTPS on port 443. The active TLS certificate was issued by Samsung Electronics OCF Server SubCA for `*.samsungiotcloud.com`. No threat indicators, blacklists, or malicious activity were detected in the observation history. Geolocation data placed the infrastructure in Columbus, OH, while the TLS certificate claimed a Korean origin, resulting in a geographic contradiction. The profile classified the intent as Legitimate Infrastructure with a low-risk reputation. Analysts were advised to Monitor the address due to signal contradictions, though no immediate firewall rules were required.
