## Recommended Actions

Immediate Blocking (Recommended)

Block this IP at the network perimeter due to high-risk classification and subnet-level abuse patterns:

```

iptables -A INPUT -s 185.255.212.0/24 -j DROP

```

Enhanced Monitoring

The subnet abuse density (37.9%) warrants ongoing monitoring. Consider:

• Blocking the entire /24 subnet if business impact allows
• Implementing rate limiting for the /23 block (185.255.212.0/23)
• Monitoring DNS queries to karnobat.net domain

DNS Filtering

Block reverse DNS resolution to the associated hostname:

```

185.255.212.8.ip.karnobat.net

```

## Intelligence Summary

IP 185.255.212.8 represents a mature malicious infrastructure component operating within a high-abuse Bulgarian hosting network. The combination of:

1. High risk score (80)

2. Subnet-level abuse density (37.9%)

3. Multiple high-risk neighbors

4. DNS blacklist prevalence (62.5%)

5. Route instability

...indicates this IP is part of an established threat infrastructure. The firewalled state suggests potential C2 server or staging infrastructure. Block immediately and monitor the entire /24 subnet.
