Binder Trace

Binder Trace is a tool for intercepting and parsing Android Binder messages. Think of it as "Wireshark for Binder".

binder-trace demo

Requirements

python version >= 3.9

⚙️ Installation

You'll need a rooted Android device or emulator.

  • (Linux only) - install xclip or xsel for "copy to clipboard" functionality

    sudo apt-get install xclip

    sudo apt-get install xsel

  • Install from PyPi

    pip install binder-trace

  • Check which version of frida is installed (make sure you've pip installed the requirements)

    pip list | grep frida

  • Download the matching version of frida-server from the frida releases page

  • Make sure adb is running as root, push frida-server to your device and run it

    adb root

    adb push frida-server /data/local/tmp

    adb shell

    chmod u+x /data/local/tmp/frida-server

    adb shell /data/local/tmp/frida-server

Arguments

Argument Description
-h Prints the argument help.
-d DEVICE The device to attach to e.g. "emulator-5554". Use adb devices to list available devices. If not provided defaults to the USB device.
-p PID The pid of the process on DEVICE to attach to.
-n NAME The name of the process on DEVICE to attach to e.g. "Messaging".
-a [9, 10, 11, 12, 13] The target device android version. If no struct path is supplied, default structs are used.
-s STRUCTPATH The path to the directory of structure files.
-c CONFIG The path to the config file to filter.
--spawn  Spawn process before attaching. -n option must be present and contain a valid process identifier.

▶️ Starting binder trace

To start binder trace we need to pick a device and process to attach to. In the following example we use adb and frida-ps to identify a process to attach to on a local emulator. As it's an Android 11 emulator we choose the Android 11 structs directory. Pick the struct directory that most closely matches your version of Android. If you would like structures for a different version of Android, please let us know. Once it's running start using the target app to generate some binder transactions.

> adb devices
List of devices attached
emulator-5554   device

> frida-ps -Ua
 PID  Name           Identifier
----  -------------  ----------------------------
8334  Messaging      com.android.messaging
7941  Phone          com.android.dialer
9607  Settings       com.android.settings

> cd binder_trace
> binder-trace -d emulator-5554 -n Messaging -a 11

🔎 Config File

To filter define any or all of the interface, method, type and inclusive options. To not use an option leave it blank ""

Without -c argument

> binder-trace -d emulator-5554 -n Contacts -a 13

Before Config

With -c argument

config.json

{
    "filters": [
        {
            "interface": "android.gui.IDisplayEventConnection",
            "method": "requestNextVsync",
            "type": "",
            "inclusive": false
        },
        {
            "interface": "android.content.IContentProvider",
            "method": "",
            "type": "call",
            "inclusive": false
        }
    ]
}
> binder-trace -d emulator-5554 -n Contacts -a 13 -c .\binder_trace\binder_trace\config.json

android.gui.IDisplayEventConnection->requestNextVsync->"" and android.content.IContentProvider->"" ->call have been filtered out

After Config

📦 Structure Compatibility

Internal binder interfaces can change around between minor versions, and since it's effectively all compiled together with no runtime version information it's hard to provide 100% accurate structure information for every release across Android's highly fragmented ecosystem.

More details on structures can be found in the structures page
