Hi

Need to crack a winrar archive, anyone got any advise as to the easiest way of doing it??

This is the first time we have come across a password protected winrar archive.

Cheers

There is no "easy" way. If the suspect used a long complicated password it is just a process of time (probably way more than you have) before you find a password that opens the archive. A DNA cluster or the Tableau accelerator will help, but by no means guarantee you will see the password any time soon. A specialized dictionary attack based on the suspect is a good place to start.

I'm already running a dictionary attack (dictionary created in FTK), i was hoping that there was an easier way!!

Hi

I've never tried it but some collegue from a Belgian FCCU recently pointed us to Rarcrack (works under linux)

"Using a brute-force algorithm, RarCrack simply gets to work determining the password for compressed archives, which, in the case of most downloaded RAR files, isn't all that tough. You can point RarCrack in the direction of any special characters you know were used in creating the password, but the standard use—rarcrack yourfile.zip—works just fine in most cases.

RarCrack is a free download for Linux systems only; Source files are available at the home page, and Ubuntu Unleashed explains how to quickly compile them.

http//sourceforge.net/projects/rarcrack/"

For those hardcore windows users, I believe that Passware software does the same, though the price is not the same.

Ultimately, I think that Accessdata Password Recovery Toolkit and Distributed Network Attack are a good buy if you do that kind of jobs on a regular basis …

Enjoy !

-)

Thanks for that i'll give it a look. I have password recovery toolkit and am running that at the moment.

Why does it not surprise me that the price is not the same for the windows version!!

Passware does have RAR key, I have it but have never used that function to know how well it works

Hi,

I am sorry i am not able to recollect the exact term for this and the tool that can hep with this.

however, the best solution is to Index the names, and strings, or commonly used filenames from the Suspect's HDD and to build a Dict file to use against this password protected winrar archive.

However, you will need a good CPU/ Dual CPU, to perform this at a very good speed, as this process is CPU intensive.

Hope this helps!
