All Zipped Up

Briefing:

Recruit, we need your scripting skills again. One of our field agents has managed to turn one of the Chiquitoos’ to act as an informant. He has obtained access to a zip file from one of the senior gang members but it’s password protected and he doesn’t know the password (although we’re pretty sure it starts with “Cola”). We’ve got a Python script that might help us brute force it but we think it needs some modifications.

Tip: Open the zip file to get the flag. And don’t forget you can use your local terminal to help.

Hint:

We believe the password starts with “Cola” and ends in numbers and upper or lower case characters.

How to Solve:

  1. In the Python script, the alphabet variable, add the entire alphabet with all caps and all numbers.
    1. From: abcdefghijklmnopqrstuvwxyz
    2. To: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890
  2. Change the first_half_password variable to Cola, from Password.
  3. Run the script normally with both files being in the same directory.
  4. Open the extracted file, Flag.txt, to get the flag.
