APKiD - Android Application Identifier for Packers, Protectors, Obfuscators and Oddities

APKiD gives you information about how an APK was made. It identifies many compilers, packers, obfuscators, and other weird stuff. It's PEiD for Android.


First, install our yara-python fork:

git clone --recursive https://github.com/rednaga/yara-python-1 yara-python
cd yara-python
python setup.py build --enable-dex install

Then, you can install apkid normally:

pip install apkid

This extra step is necessary until yara-python is updated with a version of Yara which includes the new, experimental DEX module.


If installing is too complicated, you can just use Docker! Of course, this usage requires that you have git and docker installed on your machine.

Here's how to use Docker:

git clone https://github.com/rednaga/APKiD
cd APKiD/
docker build . -t rednaga:apkid
docker/apkid.sh ~/reverse/targets/android/example/example.apk
[+] APKiD 1.2.1 :: from RedNaga :: rednaga.io
[*] example.apk!classes.dex
 |-> compiler : dx


usage: apkid [-h] [-j] [-t TIMEOUT] [-o DIR] [-q] [FILE [FILE ...]]

APKiD - Android Application Identifier v1.2.1

positional arguments:
  FILE                           apk, dex, or directory

optional arguments:
  -h, --help                     show this help message and exit
  -j, --json                     output scan results in JSON format
  -t TIMEOUT, --timeout TIMEOUT  Yara scan timeout (in seconds)
  -o DIR, --output-dir DIR       write individual results to this directory (implies --json)
  -q, --quiet                    suppress extraneous output

Submitting New Packers / Compilers / Obfuscators

If you come across an APK or DEX which APKiD does not recognize, please open a GitHub issue and tell us:

  • what you think it is

  • the file hash (either MD5, SHA1, SHA256)

We are open to any type of concept you might have for "something interesting" to detect, so do not limit yourself solely to packers, compilers or obfuscators. If there is an interesting anti-disassembler, anti-vm, anti-* trick, please make an issue.

Pull requests are welcome. If you're submitting a new rule, be sure to include a file hash of the APK / DEX so we can check the rule.


This tool is available under a dual license: a commercial one suitable for closed source projects and a GPL license that can be used in open source software.

First, you'll need to install our fork of yara-python:

git clone --recursive https://github.com/rednaga/yara-python-1 yara-python
cd yara-python
python setup.py build --enable-dex install

Then, clone this repository, compile the rules, and install the package in editable mode:

git clone https://github.com/rednaga/APKiD
cd APKiD
pip install -e .[dev]

If the above doesn't work, due to permission errors dependent on your local machine and where Python has been installed, try specifying the --user flag. This is likely needed if you are working on OSX:

pip install -e .[dev] --user

If you update any of the rules, be sure to run prep-release.py to recompile them.

For Maintainers
