pentesting-smb
Testing SMB/CIFS file-sharing services (TCP 445, and 139 over NetBIOS) on Windows and Samba hosts during authorized engagements. Covers share enumeration, null/guest session abuse, user and RID enumeration, credentialed access with netexec/crackmapexec, password spraying, command execution (psexec/wmiexec/smbexec/atexec), SAM/LSA dumping, and notable CVEs such as EternalBlue (MS17-010).

# Pentesting SMB (port 445/139)
## When to Use
- During authorized internal network or Active Directory penetration tests when TCP 445 or 139 is open
- When you need to enumerate shares, users, groups, and the domain password policy
- When testing for anonymous/null sessions, guest access, and default credentials
- When you have credentials (or NT hashes) and want to access shares, dump secrets, or move laterally
- When assessing Samba servers on Linux/Unix for dangerous `smb.conf` misconfigurations
## Quick Enumeration
```bash
# Version and vuln scan (also fingerprints OS)
