## Recommended Actions
Immediate Mitigation:
Block the IP at perimeter firewalls and WAFs due to elevated neighborhood risk and geolocation anomalies.
Platform-Specific Rules:
| Platform | Rule |
|---|---|
| iptables | `iptables -A INPUT -s 148.113.130.20 -j DROP` |
| nftables | `nft add rule inet filter input ip saddr 148.113.130.20 drop` |
| nginx | `deny 148.113.130.20;` |
| pfSense | `148.113.130.20/32` |
| Cloudflare WAF | Block with expression: `ip.src eq 148.113.130.20` |
| AWS WAF | Block address: `148.113.130.20/32` |

## Intelligence Assessment
Key Findings:
1. Geolocation Anomaly: RTT validation failure suggests potential spoofing or misreported location
2. High-Risk Neighborhood: Subnet exhibits 63.67% abuse density with 163 active threat siblings
3. Service Evasion: No open ports detected; traffic appears deliberately firewalled
4. DNS Correlation: Associated with ahrefs.net infrastructure (SEO/Marketing tool provider)
Recommendation: Monitor subnet 148.113.130.0/24 for lateral threats. Consider blocking entire /24 if traffic patterns justify broader containment.
