Introduction

The path from a foothold to total system control is defined by Privilege Escalation. This crucial phase of any penetration test or Red Team operation separates intermediate security professionals from true elite hackers. Privilege Escalation Techniques in Windows/Linux Training Course is designed to arm you with the tactical methodologies and cutting-edge exploit development skills necessary to bypass the latest security controls on both Windows and Linux environments. From abusing misconfigurations like weak file permissions and unquoted service paths to exploiting advanced techniques like Kernel Vulnerabilities and Active Directory (AD) lateral movement, this course provides a deep dive into the attacker's mindset.

Mastering PrivEsc is essential for Offensive Security professionals and defensive Blue Teams alike who seek to rigorously test and fortify their network defenses. Through extensive hands-on labs and real-world Capture, The Flag (CTF) scenarios, you will not only learn how to identify critical weaknesses like exploitable SUID/GUID binaries and vulnerable services but also how to effectively enumerate systems, weaponize custom scripts, and ultimately achieve a root shell or SYSTEM access. Elevate your cybersecurity career by mastering these high-impact techniques and become an indispensable asset in the fight against sophisticated cyber threats.

Module 5: File Permissions and Data Misconfigurations

Exploiting Weak Permissions on sensitive files like, or unencrypted Windows SAM/SYSTEM registry hives.
Abusing writable Cron Jobs and Windows Scheduled Tasks to inject malicious scripts for automated root access.
Harvesting credentials and keys from SSH keys, web application configuration files, and developer backups.
Case Study: Gaining a root shell by overwriting a script located in a writable folder that is called by a high-privilege scheduled cron job.
Advanced techniques for exploiting NFS/Samba misconfigurations.

Module 6: Windows Credential & Post-Exploitation

Using Mimikatz and similar tools to extract plaintext passwords and NTLM hashes from memory
Performing Pass-the-Hash and Over-Pass-the-Hash for lateral movement.
Techniques for manipulating the Windows Registry to achieve persistence
Case Study: Compromising a Domain User, harvesting a cached Administrator hash, and using PtH to authenticate to a Domain Controller.
Exploring fileless attack techniques and leveraging PowerShell for post-exploitation activities.

Module 7: Defensive Evasion and Advanced Tactics

Bypassing basic endpoint detection by utilizing Living Off the Land Binaries
