3.12.234.189
IP 3.12.234.189 was identified as a low-risk address with a risk score of 0. The infrastructure is owned by Amazon Technologies Inc. (AS16509) and resolves to ec2-3-12-234-189.us-east-2.compute.amazonaws.com within the US-East-2 region. Port 443 (HTTPS) was observed active, serving a TLS certificate issued by Samsung Electronics for *.samsungiotcloud.com.
Threat intelligence feeds returned no indicators for known attackers, spam sources, or Tor exit nodes. The neighborhood analysis classified the /24 subnet as clean with zero threat siblings. However, data contradictions were noted regarding geolocation, with sources disagreeing between the US and South Korea. Additionally, the TLS certificate subject indicated South Korea, conflicting with the primary US geolocation.
The recommendation was to monitor the address due to signal contradictions. No immediate blocking action was required.
