progamerz Posted October 16, 2017 Share Posted October 16, 2017 (edited) Hello, recently i bought an ebook which has an offline app for android phones, i found out the .pdf file but it is currently restricted opening it without password, is it possible to unlock it? The reason i want to do this, is to be able to print as many copies as i want. APK: https://mega.nz/#!axMV2LhB!WnJ19orjTzL1IAnOWMtcQa6EH6kEmoLhqC6Gt7vbVRs PDF: https://mega.nz/#!T4VxyZQA!5h2J36khnkDElBoHygLatM8E2aw-XMNPCDYo96B3cfc Thanks Edited October 16, 2017 by progamerz Added links Quote Link to comment Share on other sites More sharing options...

Hi G00gle Posted October 16, 2017 Share Posted October 16, 2017 (edited) Hi, Maybe this link can help you: https://www.google.nl/amp/s/www.howtogeek.com/299457/how-to-remove-a-password-from-a-pdf-file/amp/ It’s also possible with Adobe Acrobat Pro, but I’d doubt you want to pay for the solution. (You should also be able to remove the restricted access with the first option). Edited October 16, 2017 by Hi G00gle 1 Quote Link to comment Share on other sites More sharing options...

Zappster Posted October 16, 2017 Share Posted October 16, 2017 If it's propperly encrypted, then you'll have to brute the password. https://github.com/kholia/RC4-40-brute-pdf 1 Quote Link to comment Share on other sites More sharing options...

Dex Posted October 16, 2017 Share Posted October 16, 2017 The whole point of putting a password on a pdf file is securing it. I'm pretty sure you're going to have to bruteforce this one. 1 Quote Link to comment Share on other sites More sharing options...
Okabe Posted October 16, 2017 Share Posted October 16, 2017 Your best bet is giving us the pdf and the apk. Or using John The Ripper to try and brute the password on the PDF TIP: extract strings from the apk and load these into JTR as a wordlist.
