Why It's Worth Your Time
Modern Linux systems are protected by various security mechanisms, yet real-world attackers continue to find ways to bypass them and design exploits. This path offers an in-depth analysis of key Linux system hacking techniques based on real vulnerabilities, focusing on how to bypass security mechanisms through hands-on exercises. Covering advanced topics like master canary, SECCOMP, SROP, _IO_FILE structure manipulation, and environment variable exploitation, this path systematically builds practical attack skills rather than relying on theory alone. It is the ideal learning track for anyone aiming to develop professional-level Linux system hacking expertise. This path is explained based on the x86-64 architecture of the Ubuntu 22.04/18.04 Linux operating system.
Topics Covered
- Understanding SECCOMP and bypass techniques
- Stack master canary, TLS understanding, and RIP control
- Manipulating Glibc's structures like
_rtld_global
and_IO_FILE
- Leaking memory addresses via
__environ
- Controlling registers using Sigreturn-Oriented Programming (SROP)
- Building real-world exploits and gaining shell access
Recommended For
- Those who want to practice advanced Linux exploitation techniques
- Those aiming to improve vulnerability analysis and exploit design skills
- Anyone interested in memory manipulation and bypassing system defenses
Prerequisite Knowledge
- Understanding of Linux system calls and OS internals
- Knowledge of C/C++ programming and memory structures
- Experience with assembly language and debugging tools
- Familiarity with basic system hacking techniques
