- Risk Score: Moderate (50/100)
- Ownership: Ahrefs Pte Ltd Dmytro (OVH network, ASN 16276)
- Geolocation: Roubaix, Hauts-de-France, France (FR)
- Network Role: CloudCompute infrastructure (OVH-hosted, no public services)
- Threat Indicators: No direct malicious activity detected
**Key Observations**
1. Subnet Abuse Context:
- /24 subnet (176.31.139.0/24): High abuse density (0.75), with 31 sibling IPs.
- Neighbor Risk: 24 of 31 neighbors have medium/high risk scores (40–50).
- Inherited Risk: 30% of subnet’s risk profile may apply to this IP.
2. Network Behavior:
- Cloud Hosting: Identified as a cloud compute instance (OVH infrastructure).
- DNS: Resolves to `proxy-fr004-san1.ahrefs.net` (ahrefs.net domain).
- BGP: Stable route with AS_PATH `57866 16276` (OVH).
3. Historical Signals:
- No recent threats or malicious campaigns linked.
- Consistent geolocation and network stability over time.
**Threat Context**
- No Direct Threats: No indicators of C2, spam, or malware activity.
- Subnet Risks: High abuse density in the subnet suggests potential for collateral risk (e.g., misconfigured neighbors, shared infrastructure).
- Ownership: Ahrefs is a legitimate company, but OVH’s network includes both legitimate and risky IPs.
**Recommended Actions**
1. Monitor Subnet: Investigate high-risk neighbors in 176.31.139.0/24 for potential lateral movement or shared compromise.
2. Restrict Access: Apply firewall rules to limit traffic to trusted sources, especially given the subnet’s abuse profile.
3. Verify Configuration: Confirm the cloud instance’s security posture (e.g., no open ports, proper access controls).
4. Watch for Anomalies: Track changes in DNS, BGP, or network behavior that could indicate reconfiguration or compromise.
Conclusion: This IP is part of a legitimate cloud infrastructure but resides in a subnet with elevated abuse risk. While no direct threats are detected, the network context warrants closer monitoring to mitigate potential collateral risks.
