## Recommended Actions

Immediate Actions:

1. Block 111.90.159.170 at perimeter firewall due to Tor exit node classification and active blacklist presence

2. Monitor 111.90.159.151 (neighbor IP, risk score 66) for correlated activity

3. Investigate TLS certificate mismatch (issuer ≠ subject) for potential C2 infrastructure

Firewall Rules:

```

iptables -A INPUT -s 111.90.159.0/24 -j DROP

# Or for targeted blocking:

iptables -A INPUT -s 111.90.159.170 -j DROP

```

Monitoring Recommendations:

• Track route stability for ASN 45839 (unstable routing observed)
• Monitor for new blacklist additions in the 111.90.159.0/24 subnet
• Alert on any new connections to the PTR hostname server1.kamon.la

## Conclusion

IP 111.90.159.170 represents a confirmed Tor exit node operating within a Malaysian ISP infrastructure. The combination of Tor exit indicators, active blacklist presence, certificate anomalies, and neighborhood threat density warrants defensive blocking at network perimeters. The unstable routing and high-risk sibling IPs suggest broader infrastructure abuse patterns within the /24 subnet that may require subnet-level policy consideration.
