IOError: [Errno 2] No such file or directory: 'encrypted_bananas_file'

Hi

This is the output I got when I tried the script. I have a rooted device.

8.0.0
Traceback (most recent call last):
File "decrypt_photos.py", line 140, in
decrypt_bananas_file()
File "decrypt_photos.py", line 80, in decrypt_bananas_file
with open("encrypted_bananas_file") as encrypted_bananas:
IOError: [Errno 2] No such file or directory: 'encrypted_bananas_file'

Hi, can you tell me what Snapchat version are you running? Because the script works only for versions 5.0.34.X or 5.0.38.X. You can check your version under the Settings->Application Manager->Snapchat tab. If your running any of those versions, try closing the application before running the script.

It got upgraded to version 8.0.0 on 17th November. Is there any hack for that?

[xeroxnir]

I'll have to look into the new update, i'll probably take a few days to check how the learn how new version encrypts images. Thanks for reporting this.

[abhishakemitra]

please let me know if you find a hack. it's urgent. need to submit a report in 3 weeks

Hi, I just tested the script with the new version and it appeared to work. Did you close the application before running the script? are you running adb shell as root from start? (You should have # instead of $ when running adb shell). Remember the script only works for images so far, since it's a poc.

[abhishakemitra]

the app was closed but i think i missed the adb part.. so to summarise, please confirm if this is what i need to do:--
$ adb shell
#su

python decrypt_images.py

the script is saved on the Desktop currently

Hi, plese install adbd Insecure from Chainfire to make adb run as root from the start. Otherwise the script won't work because adb pull command can't pull files from internal memory.

[abhishakemitra]

but i am doing a forensic analysis currently by extracting the whole image and i have used adb pull and did not need to install any of those. But still could you please provide a link to those?

[xeroxnir]

Hi, sure, download from http://forum.xda-developers.com/showthread.php?t=1687590. The problem is using adb pull to extract something from /data/data/ folder, you need adb running as root to do that.

Thanks mate.. Will have a look and update my findings!!

Cheers!

I installed chainfire and then ran the script again.. And got the following error:--

$ python decrypt_photos.py
8.0.0

Traceback (most recent call last):

OSError: [Errno 2] No such file or directory: 'encrypted_received_image_snaps'

[xeroxnir]

Can you check if you check if you have the folder "received_image_snaps" under /data/data/com.snapchat.android/cache folder? Unloaded images are cached inside this folder when closing the application.

[abhishakemitra]

yes i do

[abhishakemitra]

[xeroxnir]

The folder is empty, apparently you have no unseen images. You must open the chat so the images are downloaded and then close the application so it's cached inside that folder. Try checking if there are images files inside that folder before running the script.
