i had an doubt "why didn't we mentioned any format for the pdf's hash?" "and the hash which seen in the pdf section how does the JTR found the hash of the password which protects the file?" pls clarify me these doubts since iam a beginner i couldn't understand them

[@Tib3rius]

PDF encryption can use a variety of techniques, so the pdf2john script pulls the hash out and labels it as a "pdf" type. I believe when john is then run against this hash, it determines which actual type it should be based on length. As for how JTR finds the hash, I'm not 100% sure, but it must logically be stored within the PDF somewhere so that the PDF decryption process can work properly in a real application. The pdf2john.pl script is very long and complex, so I imagine extracting the hash is not an easy task.

Hey Tib , I tried moving the hash1.txt to my kali box and then tried cracking it with the rules of JTR mentioned in this challenge, it doesn't crack any hash for me, same goes for the PDF hash of private.pdf But when I did it on attackbox it did why ????

[@Tib3rius]

I would ask TryHackMe in their Discord. Not sure as I never tried it this way myself, we were asked to use the Attack Box for the videos. It's possible they changed the configuration somewhere but that would be strange.
