# drozer



drozer is a security testing framework for Android.



drozer allows you to search for security vulnerabilities in apps and devices by assuming the role of an app and interacting with the Android Runtime, other apps' IPC endpoints and the underlying OS.



drozer provides tools to help you use, share and understand public Android exploits.



drozer is open source software, maintained by WithSecure, and can be downloaded from: [https://labs.withsecure.com/tools/drozer/](https://labs.withsecure.com/tools/drozer/)



## NOTE



This is an BETA release of a rewritten drozer version; this version is updated to support python3.



Currently, the following known issues are present:



- Building of custom agents functionality will crash the drozer client. This functionality is considered out of scope for the beta release of the revived drozer project.



## Docker Container



To help with making sure drozer can be run on all systems, a Docker container was created that has a working build of drozer.



* The Docker container and basic setup instructions can be found [here](https://hub.docker.com/r/withsecurelabs/drozer).

* Instructions on building your own Docker container can be found [here](https://github.com/WithSecureLabs/drozer/tree/develop/docker).



## Manual Building and Installation



### Software pre-requisites



1. [Python3.8](https://www.python.org/downloads/)

2. [Protobuf](https://pypi.python.org/pypi/protobuf) 4.25.2 or greater

3. [Pyopenssl](https://pypi.python.org/pypi/pyOpenSSL) 22.0.0 or greater

4. [Twisted](https://pypi.python.org/pypi/Twisted) 18.9.0 or greater

4. [Distro](https://pypi.org/project/distro/) 1.8.0 or greater

5. [Java Development Kit](https://adoptopenjdk.net/releases.html) 11 or greater



### Installing



You can use `pip` or `pipx` (preferably, if available) to install the latest release of drozer from our [releases](https://github.com/WithSecureLabs/drozer/releases/tag/latest):



```shell

pipx install ./drozer-*.whl

```



If you haven't already, consider running:

```shell

pipx ensurepath

```



to ensure `pipx`-installed packages appear in your `PATH`



## Building



To build drozer from source you can run.



```shell

git clone https://github.com/WithSecureLabs/drozer.git

cd drozer

pip install .

```



To build the Android native components against a specific SDK you can set the `ANDROID_SDK` environment variable to the path. For example:



**Linux/macOS:**

```shell

export ANDROID_SDK=/home/drozerUser/Android/Sdk/platforms/android-34/android.jar

```



**Windows - PowerShell:**

```powershell

New-Item -Path Env:\ANDROID_SDK -Value 'C:\Users\drozerUser\AppData\Local\Android\sdk\platforms\android-34\android.jar'

```



**Windows - cmd:**

```cmd

set ANDROID_SDK = "C:\Users\drozerUser\AppData\Local\Android\sdk\platforms\android-34\android.jar"

```



 The location of the `d8` tool used can also be changed by setting `D8`.



## Usage



### Installing the Agent



drozer can be installed using Android Debug Bridge (adb).



Download the latest drozer Agent [here](https://github.com/WithSecureLabs/drozer-agent/releases/latest).



```shell

adb install drozer-agent.apk

```



### Setup for session



You should now have the drozer Console installed on your PC, and the Agent running on your test device. Now, you need to connect the two and you’re ready to start exploring.



We will use the server embedded in the drozer Agent to do this. First, launch the Agent, select the "Embedded Server" option and tap "Enable" to start the server. You should see a notification that the server has started. 



Then, follow one of the options below.



#### Option 1: Connect to the phone via network



By default, the drozer Agent listens for incoming TCP connections on all interfaces on port 31415. In order to connect to the Agent, run the following command:



```

drozer console connect --server 

```



If you are using the Docker container, the equivalent command would be:



```

docker run --net host -it withsecurelabs/drozer console connect --server 

```



#### Option 2: Connect to the phone via USB



In some scenarios, connecting to the device over the network may not be viable. In these scenarios, we can leverage `adb`'s port-forwarding capabilities to establish a connection over USB.



First, you need to set up a suitable port forward so that your PC can connect to a TCP socket opened by the Agent inside the emulator, or on the device. By default, drozer uses port 31415



```shell

adb forward tcp:31415 tcp:31415

```



You can now connect to the drozer Agent by connecting to `localhost` (or simply not specifying the target IP)



```shell

drozer console connect

```



### Confirming a successful connection



You should be presented with a drozer command prompt:



```

Selecting ebe9fcc0c47b28da (Google sdk_gphone64_x86_64 12)



            ..                    ..:.

           ..o..                  .r..

            ..a..  . ....... .  ..nd

              ro..idsnemesisand..pr

              .otectorandroidsneme.

           .,sisandprotectorandroids+.

         ..nemesisandprotectorandroidsn:.

        .emesisandprotectorandroidsnemes..

      ..isandp,..,rotecyayandro,..,idsnem.

      .isisandp..rotectorandroid..snemisis.

      ,andprotectorandroidsnemisisandprotec.

     .torandroidsnemesisandprotectorandroid.

     .snemisisandprotectorandroidsnemesisan:

     .dprotectorandroidsnemesisandprotector.



drozer Console (v3.0.0)

dz>

```

The prompt confirms the Android ID of the device you have connected to, along with the manufacturer, model and Android software version.



You are now ready to start exploring the device.
