Brief history

All it started with two simple questions:

How we can sniff ssl traffic in order to understand which services are invoked?

and

Is there a method to automate all the process from decompile a .apk to upload on your device?

For the first questions i found a lot of guides that explain the procedure of modify the AndroidManifest.xml and the network_security_config.xml but there is not a single formula, there are different factors to understand in order to do it correctly.

For the second question is: Yes... but.

i found different types of project the on Github but they aren't completely automated in all those phases so here we are.

I read a lot of guides most of those requires to have a rooted device so i tried to create something to sniff the encrypted traffic unrooted devices in order to help all security researchers, this software is UNSTABLE for now, a lot of "unlocked" apps maybe will not work with this mod.

How it works?

ssl_pinning_remover has all the following phases:

  1. Unpack the .apk app with apktool
  2. Check if the AndroidManifest.xml has the correct attributes and if network_security_config.xml exists with the correct tags
  3. Repack the modified files in a new apk packet
  4. Sign the new apk with a self signed certificate
  5. Align the certified apk
  6. it upload the new jar in the connected android device (Optional)

Prerequisites

To use this script you need to install all those softwares in your environment:

On your device:

How to install

$ pip install -r requirements.txt
$ pip install ssl-pinning-remover

How to use

Parameter Description Mandatory
-i --input Used to specify the input .apk path Yes
-v --verbose Used to increase the stdout verbosity No
-u --upload Used to specify if you want upload the "unlocked" apk in the connected device or not No

Example

Elaborate without uploading .apk:

ssl_pinning_remover -i test.apk -v

Elaborate and upload .apk:

ssl_pinning_remover -i test.apk -v -u

The output path is the path where you launch the script. The modified apk will have the same name of the original apk but before the extension will be added ".unlocked.apk"

ToDo List

  • frida-gadget implemetation

  • Continue implementing studying difference configuration cases

  • Make the software working for most of the applications in the play store

  • Add more options

  • Code review
