If you want to dive deeper into these defensive measures, tell me:
| Phase | Action | Tool/Method | |-------|--------|--------------| | Detect | Scan for hits on exported hitlist IPs | Shodan, Censys, internal asset DB | | Block | Null route hitlist IPs at perimeter | Firewall ACL, BGP blackhole | | Investigate | Check if any internal system matches hitlist software versions | Qualys, Rapid7, custom PowerShell | | Remediate | If compromised → offline, reimage | Forensics image first, then wipe | | Report | Share anonymized hitlist hits with ISAC | Email threat intel team |
