3.136.62.26
Intelligence Briefing: 3.136.62.26
The target IP 3.136.62.26 was identified as a Web Server within Amazon Web Services infrastructure (ASN 16509, Amazon Technologies Inc.). Forward DNS resolution confirmed the hostname `ec2-3-136-62-26.us-east-2.compute.amazonaws.com`. The system operated standard HTTPS service on TCP port 443.
TLS handshake data revealed a certificate issued by Samsung Electronics OCF Server SubCA for the domain `*.samsungiotcloud.com`. Geolocation analysis presented conflicting indicators; primary sources localized the host to Columbus, OH, US, while the TLS certificate issuer country (KR) and secondary geo sources indicated Republic of Korea. Control plane analysis showed one DNSBL listing among eight checked lists, though the overall blacklist count remained at zero. Behavioral analysis recorded zero total incidents and zero honeypot strikes. The threat profile was classified as Low Risk with a risk score of 25. No active attacker status or known campaigns were associated with the address. Due to signal contradictions regarding geographic origin, the recommended action was to Monitor.
