In this tutorial, I am going to teach you how to crack a password-protected zip file. This is a very simple hack, and requires virtually no hacking skills. To crack the zip file password, we are going to perform a brute force attack with BackTrack 5 (download link below).

fcrackzip Usage:
-l (#-#): specify the minimum and maximum length of passwords to check
-b : use brute force to crack the password
-c (charset): specify the character set to use
-u : unzip / filter incorrect passwords

Note: It is illegal to crack any password-protected zip file that you do not own. I recommend creating your own password-protected zip file to practice with. The information presented in this tutorial is for educational purposes only.
