Threat Intelligence Briefing: IP Address 47.128.119.181/32

Summary:

The IP address 47.128.119.181/32 is associated with Amazon Data Services Singapore (ASN 16509) and is registered to Amazon Web Services (AWS). It is geolocated in Singapore and classified as a cloud compute infrastructure node. While the IP itself is rated Low Risk (risk score: 25), its subnet (47.128.119.181/24) contains a mix of low/medium-risk IPs, with 68% of neighbors classified as medium risk.

Key Findings:

1. Network Context:

- Hosted on AWS, likely an EC2 instance (DNS records point to `ec2-47-128-119-181.ap-southeast-1.compute.amazonaws.com`).

- Subnet 47.128.119.0/24 has an abuse density of 0.2462, indicating a small but non-negligible risk of malicious activity within the network.

2. Threat Indicators:

- No direct malicious indicators (no known campaigns, spam, or blacklists).

- Historical data shows minimal threat signals (26 pulses detected over 30 days, but no persistent malicious activity).

- No Tor exit nodes, VPNs, or CDN associations.

3. Neighbor Analysis:

- The subnet contains 85 IPs, with 68 medium-risk and 16 low-risk siblings.

- Notable neighbors include IPs with risk scores up to 40, suggesting potential for lateral movement or shared infrastructure risks.

4. Operational Context:

- AWS infrastructure is inherently secure, but misconfigurations or compromised instances could elevate risk.

- DNSSEC and CAA records are valid, but the subnet’s mixed risk profile warrants closer monitoring.

Recommendations:

• Monitor Subnet Activity: Track traffic patterns in 47.128.119.0/24 for anomalies, particularly given the presence of medium-risk neighbors.
• Verify AWS Security: Ensure the EC2 instance is configured with proper security groups, IAM roles, and access controls.
• Investigate Neighbors: Prioritize investigation of high-risk IPs in the subnet to identify potential shared vulnerabilities or malicious actors.
• Maintain Baseline: Use historical data to establish a baseline for this IP’s behavior, as no persistent threats were detected.

Conclusion:

While the IP itself is legitimate AWS infrastructure, its subnet’s mixed risk profile necessitates vigilance. SOC teams should focus on subnet-level monitoring and ensure AWS security best practices are enforced to mitigate potential risks from neighboring IPs.
