Try running it without Device #2

That helps a bit, thanks, but still some bugs. Looks like the issue is primarily with mode 14800. Mode 14700 (iOS 9-style backups) works well:

Code:
$ cat itunes-9.txt

$itunes_backup$*9*06dc04bca4eeea2fbc1bc7356fa758243bead479673640a668db285c8f48c402cc435539d935509e*10000*37d2bd7caefbb24a9729e41a3257ef06188dc01e**

$ cat mylist

The wordlist or mask you are using is too small.

Therefore, hashcat is unable to utilize the full parallelization power of your device(s).

The cracking speed will drop.

I think most of us are primarily interested in iOS 10 support. Any thoughts on these issues?

Not a bug, the speed is simply less than 1H/s (that's because they do pbkdf-hmac2-sha256 with 10 million iterations). That means the speed is not 0, but its somewhere between 0 and 1. Hashcat however does not use floating points to show the speed but integers and that's why it's round down to 0. So, it's all fine. If you have a GTX1080 you'll have ~120 H/s.

Note that it does take 4.5 minutes on your system to test 1 password, but that's not an accurate statement. It takes 4.5 minutes to test maybe a few houndret or a few thousand passwords, that's how GPU parallelizing works. It's like with Brooks's law: While it takes one woman nine months to make one baby, nine women can't make a baby in one month.

Thank you all.
I have my password again!
good job

Need to step up to the 3.40 beta.

RE: Itunes Backup - rico - 03-03-2017

Scratch that, v3.40 just released!

RE: Itunes Backup - nccpdsantry - 03-21-2017

Good afternoon,

I am attempting to use hashcat v3.40 in attempt to get the password for an encrypted itunes backup. I utilized itunes_backup2hashcat.pl thanks to philsmd and then used the following command:

hashcat64.exe -m 14800 --weak-hash-threshold 0 (insert pull from itunes_backup2hashcat.pl) (pwd dictionary).

This ran for approximately 10 hours and then I received a clwaitforevents(): CL_OUT_OF_RECOURSES
clenqueueReadBuffer(): CL_OUT_OF_RECOURSES

I did change the registry for windows 10 as stated in other posts
"TDrLevel"=Dword:00000000

any suggestions would be appreciated...

RE: Itunes Backup - atom - 03-22-2017

It's not a hashcat issue, it's a driver issue.
