SMB Enumeration

SMB (Server Message Block) is fundamental to Windows file sharing. This lesson explores smb enumeration, essential for network penetration testing.

Understanding the Topic

SMB protocol versions forms the foundation of this topic. In real-world scenarios, attackers leverage this knowledge to identify weaknesses that defenders often overlook. Understanding how smb enumeration works at a fundamental level is essential before attempting any practical exercises.

Building on that foundation, share permissions becomes critically important. Security professionals encounter this daily, and recognizing the patterns helps you work more efficiently during assessments.

Authentication methods represents another key consideration. Many beginners overlook this aspect, but experienced practitioners know it can make the difference between success and failure in real engagements.

Finally, common smb vulnerabilities provides the practical context. Knowing when and how to apply these techniques separates theoretical knowledge from actionable skills.

Tools and Environment

For smb enumeration, professionals rely on smbclient, smbmap, enum4linux, CrackMapExec. The sandbox terminal on the right provides access to these tools. Familiarize yourself with their basic usage, then answer the questions below to complete this lesson.
