Path Hijacking

Linux privilege escalation exploits misconfigurations in permissions, services, and kernel. This lesson covers path hijacking.

Understanding the Topic

SUID/SGID bits forms the foundation of this topic. In real-world scenarios, attackers leverage this knowledge to identify weaknesses that defenders often overlook. Understanding how path hijacking works at a fundamental level is essential before attempting any practical exercises.

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

Cron jobs 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, kernel exploits provides the practical context. Knowing when and how to apply these techniques separates theoretical knowledge from actionable skills.

Tools and Environment

For path hijacking, professionals rely on LinPEAS, linEnum, GTFOBins reference, pspy. 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.
