- Stability: No significant changes in risk or geolocation signals.
- Key Trends:
- Subnet abuse density remains stable at 0.5 (high risk).
- Geolocation anomalies persist (e.g., 6082km distance vs. 27ms RTT).
- No spikes in threat activity or DNS anomalies.
---
**3. Network Relationships**
- Linked Entities:
- OVH-CUST-281059698 (same network subnet).
- Ahrefs Pte Ltd (organization).
- Subnet Context:
- 15.235.98.0/24: 256 IPs, 129 flagged as high-risk.
- Abuse Density: 50.39% (high-risk subnet).
- Neighbor Risk: 20 inherited risk score from subnet.
---
**4. Neighborhood Analysis**
- Subnet Summary:
- Total IPs: 256 (15.235.98.0/24).
- Active IPs: 215 (84% utilization).
- Threat IPs: 129 (50.39% abuse density).
- Notable Neighbors:
- 15.235.98.0/24: Mixed risk scores (40โ50).
- High-Risk Neighbors: 96 IPs with medium risk, 4 with low risk.
---
**5. Actionable Insights**
- SOC Recommendations:
- Monitor Subnet: High abuse density suggests potential lateral movement or botnet activity.
- Investigate Geolocation Anomalies: Discrepancy between Canada (CA) and Singapore may indicate spoofing or misconfigured infrastructure.
- Block Neighbor IPs: Consider isolating high-risk neighbors (e.g., 15.235.98.0โ15.235.98.4) if they correlate with suspicious activity.
- Verify Cloud Provider: Confirm OVH-hosted infrastructure compliance with security best practices.
- Threat Context:
- No direct malicious indicators, but subnet-level risks warrant closer scrutiny.
- Ahrefs Pte Ltdโs infrastructure may require additional validation for potential misuse.
