**Threat Indicators**
- No direct malicious activity: No DNS abuse, spam, or known attacker associations.
- Subnet Risk: High abuse density (0.5117) in 148.113.130.0/24.
- Neighbor Analysis: 131 of 256 IPs in the subnet are flagged as threats.
---
**Network Relationships**
- Linked to OVH-CUST-281059688 (same network).
- DNS: Resolves to `proxy-ca009-san80.ahrefs.net` (Ahrefs domain).
- No TLS certificates or active services detected.
---
**Observation History**
- Stability: Unstable routing (routeChanges30d: 0, route stability: false).
- Risk Trend: Moderate risk score (40) with no significant changes in threat signals.
---
**Neighbor Subnet Analysis**
- Subnet: 148.113.130.0/24
- Abuse Density: 51.17% (high abuse classification).
- Active Siblings: 162 IPs (131 flagged as threats).
- Inherited Risk: 20 (contributing to moderate overall risk).

**SOC Actionable Insights**
1. Monitor Subnet: High abuse density in 148.113.130.0/24 suggests potential for lateral movement or compromised hosts.
2. Verify Geolocation: Investigate Singapore IP with false geoPlausible flag (RTT discrepancy may indicate spoofing).
3. Network Segmentation: Consider isolating this subnet due to high-risk neighbors, even if the IP itself is benign.
4. Check Ahrefs Context: Confirm if the cloud instance is part of legitimate Ahrefs infrastructure or a compromised asset.
