## SECURITY RECOMMENDATIONS
Risk Assessment: Monitor/Block Based on Organizational Policy
Action Confidence: Moderate (Risk Score 40 with high-abuse subnet context)
Recommended Firewall Rules:
```bash
# iptables
iptables -A INPUT -s 167.114.139.64 -j DROP
# nftables
nft add rule inet filter input ip saddr 167.114.139.64 drop
# Cloudflare WAF
{
"description": "Block 167.114.139.64 โ IPDebrief risk score 40",
"action": "block",
"filter": {"expression": "ip.src eq 167.114.139.64"}
}
# AWS WAF
{
"Addresses": ["167.114.139.64/32"],
"Description": "IPDebrief risk 40"
}
```
Note: These recommendations are probabilistic and should be combined with other signals before taking action.

## ANALYST NOTES
1. Contextual Risk: The IP resolves to legitimate ahrefs.net infrastructure but operates within a high-abuse density OVH subnet. This suggests potential credential sharing or resource contention.
2. Service Status: No open ports or services detected (firewalled). This reduces exploitation surface but may indicate legitimate proxy or residential forwarding service.
3. Recommendation: Implement monitoring or blocking depending on organizational threat posture. If blocking, consider subnet-level rules (167.114.139.0/24) given the 130 threat sibling count, but evaluate business impact first.
