Installation

It's fairly simple to install APKLeaks:

from PyPi

$ pip3 install apkleaks

from Source

Clone repository and install requirements:

$ git clone https://github.com/dwisiswant0/apkleaks
$ cd apkleaks/
$ pip3 install -r requirements.txt

from Docker

Pull the Docker image by running:

$ docker pull dwisiswant0/apkleaks:latest

Dependencies

The APKLeaks utilizes the jadx disassembler to decompile APK files. If jadx is not present in your system, it will prompt you to download it.

Usage

Simply,

$ apkleaks -f ~/path/to/file.apk
# from Source
$ python3 apkleaks.py -f ~/path/to/file.apk
# or with Docker
$ docker run -it --rm -v /tmp:/tmp dwisiswant0/apkleaks:latest -f /tmp/file.apk

Options

Here are all the options it supports.

Argument	Description	Example
-f, --file	APK file to scanning	apkleaks -f file.apk
-o, --output	Write to file results (random if not set)	apkleaks -f file.apk -o results.txt
-p, --pattern	Path to custom patterns JSON	apkleaks -f file.apk -p custom-rules.json
-a, --args	Disassembler arguments	apkleaks -f file.apk --args="--deobf --log-level DEBUG"
--json	Save as JSON format	apkleaks -f file.apk -o results.json --json

Output

In general, if you don't provide -o argument, then it will generate results file automatically.

NOTE: By default it will also save the results in text format, use --json argument if you want JSON output format.

Pattern

Custom patterns can be added with the following argument to provide sensitive search rules in the JSON file format: --pattern /path/to/custom-rules.json. If no file is set, the tool will use the default patterns found in regexes.json file.

Here's an example of what a custom pattern file could look like:

// custom-rules.json
{
  "Amazon AWS Access Key ID": "AKIA[0-9A-Z]{16}",
  // ...
}

To run the tool using these custom rules, use the following command:

$ apkleaks -f /path/to/file.apk -p rules.json -o ~/Documents/apkleaks-results.txt

Arguments (disassembler)

We give user complete discretion to pass the disassembler arguments. For example, if you want to activate threads in jadx decompilation process, you can add it with -a/--args argument, example: --args="--threads-count 5".

$ apkleaks -f /path/to/file.apk -a "--deobf --log-level DEBUG"

Warning: Please pay attention to the default disassembler arguments we use to prevent collisions.
