As we progress further in the Bandit Challenge, Level 9 ↗️ presents us with a new puzzle. Our objective is to find a password hidden within a file called “data.txt,” where the password is the only line of text that occurs only once.
Level 9 challenges us to search for a password within the “data.txt” file, where the password is the only line of text that occurs only once. We need to identify the unique line and extract the password from it.
By using commands like
uniq we’ll search for the unique line, manipulate the output, and successfully obtain the password.
Follow these steps to successfully solve Level 9:
Enter the password you obtained from the previous level.
To search for the password line that occurs only once in the “data.txt” file, use the following command:
The sort command sorts the lines in the file, and the
uniq -u command prints only the unique lines, filtering out any duplicated lines.
The output of the command will display the unique line that contains the password. Make a note of this password for next level.
- Use the
-uoption with uniq to print only the unique lines.
- Remember to utilize appropriate piping and redirection techniques to process the output of commands.
Congratulations on successfully completing Level 9 of the Bandit Challenge! By searching for the unique line containing the password within the “data.txt” file, we have obtained the necessary password to progress further.
Stay tuned for the next blog post, where we’ll tackle Level 10 and face new challenges in our quest to become proficient cybersecurity practitioners.
