Risk Assessment
The IP presents moderate risk primarily due to subnet-level abuse density rather than direct malicious indicators. The high-abuse /24 subnet (192 threat siblings) suggests this is part of a compromised or misconfigured hosting environment. The geolocation inconsistency and RTT anomaly indicate data reliability concerns that may impact threat correlation accuracy.
Recommended Actions
| Priority | Action | Rationale |
|---|---|---|
| **HIGH** | Block at network perimeter | Subnet abuse density (0.75) indicates elevated threat presence |
| **MEDIUM** | Monitor DNSBL listing trends | 1 of 8 DNSBL lists suggests potential reputation issues |
| **LOW** | Validate service exposure | No open ports detected; may indicate legitimate cloud infrastructure |
| **LOW** | Review geolocation consistency | RTT anomaly suggests location data is unreliable for correlation |
Intelligence Notes
- Target IP is firewalled with no services exposed, limiting direct exploitation vectors
- Hostname mapping to ahrefs.net may indicate legitimate use or compromised infrastructure
- Cloud hosting environment limits visibility into underlying infrastructure
- No active campaigns or certificate-based threats detected
- Consider blocking /24 subnet if threat context supports broader mitigation
