## NEIGHBORHOOD ANALYSIS
Subnet: 47.128.119.141/24
Total Siblings: 98 IPs
Active Siblings: 75 IPs
Threat Siblings: 48 IPs (48.98% abuse density)
Classification: Mixed
Risk Distribution in /24:
- High Risk: 0 IPs
- Medium Risk: 70 IPs
- Low Risk: 27 IPs
Analysis: The /24 subnet demonstrates elevated abuse density (0.4898) with nearly half the sibling IPs flagged as threats. This pattern is consistent with cloud infrastructure hosting environments where legitimate services coexist with compromised instances. The target IP itself maintains a low-risk score (25) despite neighborhood context.

## DEFENSIVE RECOMMENDATIONS
Primary Assessment: No blocking required. IP represents legitimate cloud infrastructure.
Recommended Actions:
1. Allow Traffic: No firewall rules required for this IP.
2. Monitor: Continue standard monitoring of associated AWS region (ap-southeast-1).
3. Contextual Review: If this IP appears in suspicious logs, correlate with other indicators before taking action. The elevated neighborhood abuse density warrants awareness but does not justify blocking the target IP.
Threat Hunting Notes:
- Monitor for anomalous behavior patterns from this AWS instance (e.g., unexpected outbound connections, data exfiltration attempts).
- Correlate with other IPs in the 47.128.119.0/24 subnet if broader subnet compromise is suspected.
- Review AWS security groups and access control lists for this instance if lateral movement is detected.
---
Analyst Notes: The target IP represents standard cloud infrastructure with no evidence of malicious activity. While the /24 subnet shows elevated abuse density (48 threat siblings), this is characteristic of cloud hosting environments. Maintain contextual awareness but no immediate defensive action is warranted for IP 47.128.119.141.
