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.

For more information on what this tool can be used for, check out:

Installing
The yara-python clone and compile steps here are temporarily necessary because we must point directly to our modified version of a Yara branch which includes our DEX Yara module. This step is nessecary until (if?) the original maintainers of Yara merge our module into the master branch. When this happens, we will undate the instructions here. After the yara-python fork is compiled, you can use pip to the most currently published APKiD package.

git clone https://github.com/rednaga/yara-python
 cd yara-python
 python setup.py install
 pip install apkid

Usage

usage: apkid [-h] [-j] [-t TIMEOUT] [-o DIR] [FILE [FILE ...]]
 
 APKiD - Android Application Identifier v1.0.0
 
 positional arguments:
   FILE                  apk, dex, or directory
 
 optional arguments:
   -h, --help            show this help message and exit
   -j, --json            output results in JSON format
   -t TIMEOUT, --timeout TIMEOUT
                         Yara scan timeout (in seconds)
   -o DIR, --output-dir DIR
                         write individual JSON results to this directory

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.
You're also welcome to submit pull requests. Just be sure to include a file hash so we can check the rule.

Hacking
First you will need to install the specific version of yara-python the project depends on (more information about this in the Installing section):

git clone https://github.com/rednaga/yara-python
 cd yara-python
 python setup.py install

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

git clone https://github.com/rednaga/APKiD
 cd APKiD
 ./prep-release.py
 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:
