FAIL: could not read /keybags/systembag.kb from data partition #76

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Reported by h2spice ;

When I try to run python python_scripts/emf_decrypter.py,

I get,

r3d4l3rtui-MacBook?-Pro:python_scripts h2spice$ python emf_decrypter.py 
../../../../rdisk0r1r2.dmg

Using plist file ../../../../Encription.plist

Keybag unlocked with passcode key

cprotect version : 4 (iOS 5)

FAIL: could not read /keybags/systembag.kb from data partition

Traceback (most recent call last):

File "emf_decrypter.py", line 34, in <module>

main()

File "emf_decrypter.py", line 19, in main

if not v.keybag.unlocked:

AttributeError?: 'bool' object has no attribute 'unlocked'

r3d4l3rtui-MacBook?-Pro:python_scripts h2spice$

Can you advise why the error might be causing this?

Thanks.

Can you try to add this line to the file python_scripts/util/bruteforce.py at 
line 25 :
print "systembag is None :", (systembag ==None)

and then run the command again and post this new line from the output.

Also, can you post the commands you used to get the Encription.plist and 
rdisk0r1r2.dmg.
I assume you used the latest revision of the tools from the repository ?
Thanks

ok, 

first, try to add this line to the file python_scripts/util/bruteforce.py at

    if not systembag or not systembag.startswith("bplist"):
        print "FAIL: could not read /keybags/systembag.kb from data partition"
        return False

and then run the command again

ok, what is the value of the dataVolumeOffset field in the plist file ?

OK, can you try to open the disk image with the modified HFSExplorer 
(http://code.google.com/p/iphone-dataprotection/downloads/detail?name=hfsexplore
r_iphoneEMF_d4ea02bd3fc3.zip&can=2&q=)

And open a random file in the image, for instance /logs/lockdownd.log, the file 
should contain text.

GoogleCodeExporter commented 9 years ago 
yes ,

after download HFSexplorer, i did open the image rdisk0s1s2.dmg.

 as you said, i did open the tile /logs/lockdownd.log, this file contain text

PS. attach file : lockdownd.log

ok, it seems the dataVolumeOffset field is wrong, lockdownd.log is decrypted 
incorrecty, it should contain ascii text. You can try running the attached 
python script (find_dataVolumeOffset.py) on the disk image, it will try all 
possible values for this parameter and display the correct one.
If the script finds the right value, you can replace it in the plist file and 
then emf_decrypter should work OK.

Also, if you can post the correct value, and dump just the first 4k of 
/dev/rdisk0 and post it here, it would help figure out why the value was wrong 
in the first place . Thanks

ha yes sorry, you need to comment line 120 in hfs/emf.py
self.keybag = loadKeybagFromVolume(self, device_infos)
=>
#self.keybag = loadKeybagFromVolume(self, device_infos)

@h2spice Can you describe how you solve this problem? I have the same problem 
and I can't solve it yet. Thanks!

@jcruzq78 you can try running the script attached in comment 9 (place it in the 
python_scripts folder, also make sure to comment line 120 in 
python_scripts/hfs/emf.py). If it works then you can edit the plist file you 
got when running the tools and replace the dataVolumeOffset value with the one 
given by the find_dataVolumeOffset script.

GoogleCodeExporter commented 9 years ago 
ok, thanks

when i tried to execute python module(find_dataVolumeOffset.py), got 
dataVolumeOffset.

after replace the dataVolumeOffset, you can execute python 
module(emf_decrypter.py).

: )
