This module walks you through the basics of using pwn.college, running challenges, and capturing flags! We suggest completing all of the challenges in this module and the Linux module, from there you can skip around to whatever sounds interesting!

A few helpful definitions to get you started:

Terminal - a different way to interact with a computer. Normally, you click buttons and open apps. With the terminal, you type commands directly to the computer. You may also see this referred to as the command line.
Command - an instruction that you type to tell the computer to perform a specific task. Like viewing/editing files or running a program.
File - a place to store data on your computer. You likely have experience with Word Documents (text files) or photos (image files).
Folder/Directory - both terms are used to describe a group of files stored together. We use folders/directories to organize our filesystem. A given folder can contain many files, and sub-folders within it.
Filesystem - all of the files on your computer.
Code - a set of steps/instructions for the computer to perform, that ultimately completes a task.
Programming language - all code is written in a specific programming language. Programming languages allow you (the programmer) to communicate directly with the computer. The programs you write can perform many different tasks, such as calculations, data processing, games, etc.
Linux - an operating system. This is how the computer works. You may have experience with a Windows or Mac computer. Linux is very similar to both Windows and Mac, but has a few different features. The terminal you use in VSCode is a Linux terminal.
Virtual Machine - essentially a fake/pretend computer inside a real computer! Virtual machines (or VMs) allow you to run programs or even different operating systems without needing a second physical computer. In all of these challenges, you will be accessing a VM through the web browser!

Challenges

Our first challenge is learning to use the Desktop! The GUI Desktop is a virtual machine running a Linux operating system. After finishing this module, try out the challenges in the Linux module to learn more about how to use it!

Challenge steps

Start the challenge
Open the GUI Desktop - either click "Desktop" in the top navigation tab, or "GUI Desktop Workspace" when the blue banner pops up below.
Open a terminal inside the Desktop - click the black box at the bottom of the desktop
Once the terminal is open, your flag will appear!
Follow the steps given in the terminal to submit your flag. Copy/pasting from the Desktop is a bit tricky!

Next, we will learn to paste into the Desktop! You will need this secret token: ThisIsYourSuperSecretTokenThatYouNeedToCopyIntoTheDesktop Launch a terminal in the desktop for further directions!

Note that the secret token is NOT your flag. Flags will always look like pwn.college{...}

Challenge Steps

Start the challenge and open the Desktop
Open a terminal and follow the directions
Submit your flag! Remember that you'll need to use the clipboard again to copy/paste it :)

Challenge Description

Most challenges will have files stored in the /challenge directory. A directory is just a folder that you can store files in. The last challenge ran a file automatically when the terminal was opened, but this challenge requires you to run the file yourself.

You will need to run the /challenge/solve file to get the flag. There are a few different ways to run files, depending on the file type. For most challenge files, you will simply need to type the name of the file (including the direcory) into the terminal and hit Enter.

Challenge Steps

Start the challenge and open the Desktop
Open a terminal
Type /challenge/solve in the terminal and press Enter
Submit the flag!
