- Historical data shows no persistent malicious behavior (threat persistence days = 0).
- DNS & Services:
- No open ports, TLS certificates, or HTTP server banners detected.
- DNSSEC and CAA records are valid but show some DNSBL (blacklist) listings.
---
**3. Network Relationships**
- Key Associations:
- Linked to wispernet (CDSL-MNT subnet: 91.226.112.0/22).
- DNS queries timed out for internal hosts (192.168.2.108), suggesting potential misconfiguration.
- Subnet Context:
- 91.226.115.52/24 subnet has moderate abuse density (0.6364).
- 7/11 sibling IPs show risk scores ≥ 55, with 2 high-risk peers (score 80).
---
**4. Subnet Analysis**
- Neighbor Risk Distribution:
- High Risk: 2 IPs (e.g., 91.226.115.63, 91.226.115.123)
- Medium Risk: 8 IPs
- Low Risk: 1 IP
- Subnet Abuse Density: 63.64% (high abuse classification).
- Recommendation: Monitor high-risk neighbors for lateral movement or shared infrastructure compromises.
---
**5. Threat & Mitigation Summary**
- No Direct Threat: No indicators of compromise (IOC) or malicious campaigns.
- DNS & Network Risks:
- DNS misconfigurations may impact network reliability.
- Subnet abuse density suggests potential for peer-based threats.
- Action Plan:
- Block high-risk subnet peers (e.g., 91.226.115.63) using firewall rules.
- Validate DNS configurations to resolve timeout issues.
- Monitor for changes in subnet abuse density or new threat indicators.
