Learn how to assess a Linux box for root access by gathering system information, checking for exploits, reviewing command history, and evaluating brute-force and SSH login risks.
Explore how older sudo versions, from 1.8 to 1.9.5, could escalate privileges to root on Linux systems. Identify vulnerable versions using sudo --version and understand the root access risk.
Uncover how command history and bash history can reveal passwords when admins forget to clear or delete history, highlighting security risks in Linux systems.
Examine how restricted commands via sudo and command whitelisting can be exploited to gain root access, using GTFO bins to identify vulnerable commands.
Investigate how file permissions expose password hashes in /etc/shadow. Learn why Linux uses hashing for passwords and how tools like John the Ripper crack those hashes.
Linux is one of the most widely used systems in the world. Do you know how to hack it? Hacking linux is hard work. We make it easy. In this course you will learn how to execute a basic hack and then different techniques you can use to become administrator (root) in the Linux system.
It is recommended that you have some basic knowledge of the Linux command line before starting this course. We will be using a Linux based system called Kali Linux. Kali is a security and hacking orientated system.
You can use what you learn in this course to hack other Linux computers or to increase the security of your own Linux computer. In order to prevent getting hacked, you have to think like a hacker. Whichever your purpose, this course will leverage your skills from basic Linux user to knowledgeable on compromising Linux systems.
Once you hacked the system, you will want to increase your privileges on the system. Instead of a regular user, why not become administrator (root) on the system you just hacked? In this course you will learn different techniques that let you do that.
We will cover the following:
Basic Hacking into Linux (any Linux based system)
Techniques to become Root
Automated Scanning for vulnerabilities
