Conclusion:

18.144.3.82 is a standard AWS cloud infrastructure IP with moderate risk due to inherited subnet factors. No direct malicious indicators are present, but SOC teams should monitor for anomalies in traffic patterns or subnet-level threats.

Recommendation:

• Continue standard cloud security hygiene practices for AWS-hosted assets.
• Investigate the threat sibling in the subnet if further context or alerts emerge.
