Lab Walkthrough Video:


An encrypted PDF (1.4-1.6) file is provided. The password was chosen either from a dictionary or using the password policy. The pdf file is present in the user's home directory and the dictionary file "1000000-password-seclists.txt" is present in the wordlists directory.

Objective: Recover the password, decrypt the PDF and retrieve the flag!

If the dictionary attack does not work then the Password Policy could be:
  • Password length is less than 6 characters i.e. 0 < length < 6
  • Password can only contain characters from this character set:  a-z, 0-9

John the Ripper and Hashcat are available on the system.

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  attackdefense@pentesteracademy.com  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
