This file may contain other hashes. Another option is to use a BackTrack Linux instance, available at backtrack-linux. The hashes can be loaded using the command in Figure 8. The only thing to do now is wait … and wait … and wait….
This particular hash crack was performed on a 2. The more powerful the system the faster the cracking. Figure 9 shows the password was cracked in approximately 21 hours. Figure 8 - Password Hashes loaded into John the Ripper. The next steps is to access the unencrypted disk image and image the sparsebundle in a forensically sound manner. The hdiutil tool is used to manipulate disk images. In this instance, the verb attach is used to access the disk image as if it were a removable drive.
When the correct password is entered, it will display the partitions of the disk image shown in Figure Figure 10 - Use hdiutil to access the Sparsebundle. To create a dd image of the disk image, issue the following command. This command splits the disk image into 2GB chunks onto a specified volume. Be aware that the size listed in the Info.
There is definitely more than one way to go about cracking open a FileVault encrypted home directory. There are commercial tools available for a price that can make the process much easier and probably quicker. This is a budget-friendly process for those folks who can spare the time but maybe not the dollars. Or can I somehow use these to decode the sparsebundle? I changed permissions so that I could access the sparsebundle From something I read, I am led to believe that the sparsebundle's hash might be unsalted because it's an upgraded Mac?
I assume that meant because it was calculated in an older version of OSX that didn't salt the hashes, but I don't really know. With regards to the master. It doesn't really matter I suppose, as trying to crack it would likely be too difficult since I'd have to just brute force it with upper and lower case letters, symbols and characters.
I have a forensic computer with 3xATI video cards ready and waiting, but it said something like , years. Side question: is it possible to use a dictionary list as words that the password will NOT be?
The password here, if you remember, was the first letter of every word of some phrase so it's definitely NOT an english word or a variant of one. So, I guess I'm gonna give cracking the sparseimage bundle a try; can anyone tell me how to get the hash for it?
Is this the hash of the filevault password for the user, or just of the user's login password? What I read was somewhat unclear on that point and the directions on how to pull the hash from the GUID file were kinda confusing. Whether this is by unlocking the filevault. If you know how I can get it done, I'm all ears. Does it only work on Maverick? If you can unlock the FileVaultMaster. I have a guide available from here in PDF format:. That section covers troubleshooting and data recovery for legacy FileVault.

The long version: This involves a Macbook Pro running Mountain Lion where the user changed their user password and cannot remember either the original password, nor the password it was changed to.
Any help would be welcomed- thanks in advance for the answer ;. Improve this question. Enable the root user. Write down the password assigned to root. Restart the Mac in Safe Mode. Drag the username.
Select the username. Type the Master Password when prompted. If Repair Disk completes with the message:. The volume username appears to be OK. No problems were found. See screen shot at right. The volume username has been repaired. Problems were found and corrected. You may wish to click Verify Disk to confirm this. The sparse bundle could not be repaired: see "Disk Utility cannot repair the sparse bundle" below.
It will disappear in a puff of smoke.
