Leviathan: Level 0 - Level 1

Level 1

Username: leviathan0 Password: leviathan0

Task:

Start

Let’s begin by connecting to the server leviathan.labs.overthewire.org and logging in with user leviathan0 on port 2223.

Exploring Enviroment

Check the environment first. With pwd we can find our where we are.

With ls we check which files and folders are in our current directory. It seems nothings here … but what if there is a hidden directory or file?

With ls -la we can check the permissions of all files in this directory.

There is a hidden folder .backup.

What could be inside this folder?

cd .backup

and again - what is inside?

ls -la

We found a file bookmarks.html. We can print out a few lines of this file via head

head bookmarks.html

Solve the level

okay - how can we find out the password for the next level without reading the whole file?

Yes - we can search for it. Lets try it with the word password or leviathan1

cat bookmarks.html |grep "password" 

Looks good, we have our password

Now we have the password for Level 1:

3QJ3TgzHDq

Explanation hidden files:

Why Hidden Files? Hidden files in Linux start with a dot (.) and are used to keep configuration files and system data out of sight. This helps avoid clutter in your working directory and keeps important system files organized.

How to Find and Explore Hidden Files

1. Find Your Location
   Use pwd to see where you are in the file system.

2. List All Files
   By default, ls only shows visible files. To include hidden files, use ls -la:
   • -l provides a detailed list, including file permissions, ownership, and modification dates.
   • -a includes hidden files (those starting with a dot).
3. Explore Hidden Directories
   If you find a hidden directory, like .backup, navigate into it with cd .backup. Then use ls -la again to see the contents of this directory.
