Itunes Backup

[joswr1ght]

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
password1
password2
test123
badpassword
$ ~/Hack/hashcat/hashcat -m 14700 -d3 --weak-hash-threshold 0 itunes-9.txt mylist

Mode 14700's benchmark feature also works OK:

Code:

$ ~/Hack/hashcat/hashcat -m 14700 -d3 -b

With iOS 10 however, it takes 4.5 minutes to crack the password:

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?

Thanks!
