# Exploiting SMB Vulnerabilities with Metasploit
## When to Use
- Testing Windows systems for critical SMB vulnerabilities (EternalBlue, EternalRomance, PrintNightmare) during authorized penetration tests
- Demonstrating lateral movement risks via SMB relay, pass-the-hash, and credential spraying
- Validating that patch management processes have addressed known SMB vulnerabilities
- Assessing SMB signing enforcement and share permission configurations across the domain
- Testing network segmentation by attempting SMB exploitation across VLAN boundaries
**Do not use** against systems without explicit written authorization, against production domain controllers without a maintenance window, or to deploy persistent backdoors beyond the scope of the assessment.
## Most Often Missed & How to Confirm
- **Signing-disabled relay (most-missed win):** `crackmapexec smb <range> --gen-relay-list targets.txt` lists hosts with `signing:False` — relay targets for `impacket-ntlmrelayx`, independent of any CVE. A fully patched host can still be owned via relay if SMB signing is not *required*.
