If somebody creates a PDF and then loses the password, they can recover the password with the pdfcrack command line password recovery tool. The tool leverages a brute force attack against the PDF password until it opens. The attack proceeds offline and nothing is exchaned via the Internet. Owner passwords can be found with the -o switch. Password cracking of longer passwords can take days or weeks to crack, so we limit the password length to 9 characters. This hack can not and does not work over the Internet with content locked by a 3rd party JS plugin. How could it? It would have to hack into the 3rd party server to do that!
