JSut Duck It Up

Question

What in the world could this be?!?! file

HINTS

Maybe start searching for uses of these chunks of characers? Is there anything on the Internet with them?

Solution

This challenge was good not that much hard. It just depends on your google finding skills.

  1. In this challenge we got one file name:

    file

  2. Now I checked for the file type

    $file file
file: ASCII text, with very long lines, with no line terminators

  3. Now we see this is ASCII text so i quickly opend it and we saw this:

    $cat file | more

    1. Then i copied first 2 [] brackets and putted in the google search and i saw javascript was written in most of the articles then i again checked the name JSut here JS was in the only capital letters. So, maybe it's JavaScript? Then why dont run it in the inspect element's console?

    Copy the JS code from file > Open inspect elements > Click on console > paste the code their > Hit Enter

    Bang and we saw a PopUP xD

    So, i think we got the flag
