PDF Password Hacker: How to Crack or Hack Password-protected PDF Files

Unfortunately, in spite of the best interests of the creator of the PDF document to secure the text or other content contained in the file, password protected PDFs can easily be cracked and the document security features removed. A simple search on any major search engine will reveal numerous PDF password removal applications and workarounds that are easily and freely available online. These can be used in unlocking almost any secure PDF for unauthorized edits, sharing, and use with optical character recognition software.

In most cases, the document owner is rarely aware that their passwords have been compromised and if the hacker is smart, the fact that the attack has taken place also might never be discovered. For organizations and companies, this means that sensitive business data can be easily duplicated, edited, deleted or even read by unauthorized sources without anyone even knowing a security breach has occurred.

Cracking Password Protected PDF Files

In spite of technological advancements and education surrounding the importance of strong passwords for confidential business information, a large number of companies still have a poor understanding of how easy it is for anybody outside the system to subtly hack into their data. Standard password-based PDF documents are often reused with the same credentials and in most cases these credentials are stored in a password database that is typically maintained on the company’s system. Hence the password to the document can either be acquired by snooping on the user’s network connection, hacking the system’s password file, keyboard tapping or keystroke capturing, stealth infection, searching online for a simple password removing application, or simply by guessing the password or using dictionary attacks. There are a number of powerful password cracking applications that are able to decrypt any password within seconds or minutes through a standard computer – the shorter the password the quicker it is to crack.

On the other hand, removing the user or open password is extremely difficult. There are tools like Elcomsoft PDF Password Recovery but they don’t guarantee 100% success rate. Also, all these software available to crack open or user password are CPU-intensive, and even the simplest passwords can take days to crack. In others words, removing the user or open password from a PDF file is next to impossible.

In most countries, the only legal use of PDF password crackers is to break the security on a PDF file that you have the permission to do so on, like a PDF you encrypted but forgot the password to.

PDFCrack would be considered a true PDF password recovery program since it recovers both the user password and owner password from encrypted PDFs. PDFCrack uses a brute-force password recovery method.

PDFCrack recovered the 4-digit owner password on a version 1.6 PDF file with 128-bit RC4 encryption in two minutes. A longer and/or more complicated PDF password could take days, weeks, or even longer to recover.

If all you need is a way to bypass the permissions security in a PDF then PDFCrack is probably more than you need in a PDF password cracker. However, if you need to know the actual owner or user password, PDFCrack is your best bet.
