Install

Note

Below scripts might require sudo access to install certain packages and dependencies. Review the scripts before running them.

wget -qO - https://raw.githubusercontent.com/adityatelange/MobSleuth/main/install.sh | bash

Tools can be installed one by one.

cd $HOME/MobSleuth/src
bash install/common_deps.sh
bash install/docker.sh

Logout and login again to apply group changes as we have added user to docker group.

Continue installing rest of the components.

cd $HOME/MobSleuth/src
bash install/redroid.sh
bash install/mobsf.sh
bash install/scrcpy.sh
bash install/frida.sh
bash install/jadx.sh
bash install/burpsuite.sh
bash install/objection.sh
bash install/pidcat.sh

After Installation

All the tools are installed in the ~/MobSleuth directory.

• ~/MobSleuth/src - contains the installation scripts. You may update MobSleuth using git pull in this directory.
• ~/MobSleuth/installers - contains the downloaded installers.
• ~/MobSleuth/data11_vol - contains the data directory for the reDroid container for persistence.
• ~/MobSleuth/mobsf_vol - contains the data directory for the MobSF container for persistence.
• ~/MobSleuth/tools - contains the tools installed.
• ~/MobSleuth/certs - contains the generated CA certificate and private key.

Usage

Start the containers

cd $HOME/MobSleuth
bash run/run_mobsleuth_services.sh

This will start the following services:

• reDroid - Android container accessible on port 5555
• MobSF - Mobile Security Framework accessible on port 8000

Generate CA certificate

cd $HOME/MobSleuth
bash scripts/generate_cert.sh

Install CA certificate on the Android container

Make sure the Android container is running.

cd $HOME/MobSleuth
bash scripts/push_cert.sh

Import CA certificate in BurpSuite

• Open BurpSuite and go to Proxy > Proxy Settings
• Select an Interface and click on Edit.
• Click on Import / export CA Certificate.
• Select Certificate and private key in DER format and click Next.
• In CA Certificate, select ~/MobSleuth/cert/certificate.der and in Private key, select ~/MobSleuth/cert/certificate_private_key.der.
• Click Next and OK.

Set/Unset BurpSuite Proxy in the Android container

cd $HOME/MobSleuth
bash run/set_proxy.sh

Unset using:

cd $HOME/MobSleuth
bash run/unset_proxy.sh

Access MobSF

Open your browser and go to http://localhost:8000.

Access reDroid

Connect to the Android container using scrcpy or adb.

Mirror Screen using scrcpy:

scrcpy

Connect using adb:

adb connect localhost:5555

ADB shell:

adb shell

Rooting the Android container

Make sure the Android container is running. Then run the following command.

adb root

Using Frida

Push frida-server and run it on the Android container.

cd $HOME/MobSleuth
bash scripts/push_fridaserver.sh
bash scripts/run_fridaserver.sh

Now we can use frida to interact with the Android container.

frida-ps -U

Access jadx/objection/pidcat

These tools can directly accessed using the terminal.

jadx

objection

pidcat

Uninstall

This will remove all the tools and the containers. Be careful before running this command.

sudo rm -rf $HOME/MobSleuth
