APKDeepLens is a Python based tool designed to scan Android applications (APK files) for security vulnerabilities. It specifically targets the OWASP Top 10 mobile vulnerabilities, providing an easy and efficient way for developers, penetration testers, and security researchers to assess the security posture of Android apps.
APKDeepLens is a Python-based tool that performs various operations on APK files. Its main features include:
To use APKDeepLens, you'll need to have Python 3.8 or higher installed on your system. You can then install APKDeepLens using the following command:
FreshRSS git clone https://github.com/d78ui98/APKDeepLens/tree/main
cd /APKDeepLens
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python APKDeepLens.py --help
git clone https://github.com/d78ui98/APKDeepLens/tree/main
cd \APKDeepLens
python3 -m venv venv
.\venv\Scripts\activate
pip install -r .\requirements.txt
python APKDeepLens.py --help
To simply scan an APK, use the below command. Mention the apk file with -apk argument. Once the scan is complete, a detailed report will be displayed in the console.
python3 APKDeepLens.py -apk file.apk
If you've already extracted the source code and want to provide its path for a faster scan you can use the below command. Mention the source code of the android application with -source parameter.
python3 APKDeepLens.py -apk file.apk -source <source-code-path>
To generate detailed PDF and HTML reports after the scan you can pass -report argument as mentioned below.
python3 APKDeepLens.py -apk file.apk -report

This is an alpha release of an assemblies.blob AssemblyStore parser written in Python. The tool is capable of unpack and repackaging assemblies.blob and assemblies.manifest Xamarin files from an APK.
Run the installer script:
python setup.py install
You can then use the tool by calling pyxamstore
I recommend using the tool in conjunction with apktool. The following commands can be used to unpack an APK and unpack the Xamarin DLLs:
apktool d yourapp.apk
pyxamstore unpack -d yourapp/unknown/assemblies/
Assemblies that are detected as compressed with LZ4 will be automatically decompressed in the extraction process.
If you want to make changes to the DLLs within the AssemblyStore, you can use pyxamstore along with the assemblies.json generated during the unpack to create a new assemblies.blob file(s). The following command from the directory where your assemblies.json file exists:
pyxamstore pack
From here you'll need to copy the new manifest and blobs as well as repackage/sign the APK.
Additional file format details can be found on my personal website.
The security of mobile devices has become a critical concern due to the increasing amount of sensitive data being stored on them. With the rise of Android OS as the most popular mobile platform, the need for effective tools to assess its security has also increased. In response to this need, a new Android framework has emerged that combines three powerful tools - AndroPass, APKUtil, RMS, and MobFS - to conduct comprehensive vulnerability analysis of Android applications. This framework is known as QuadraInspect.
QuadraInspect is an Android framework that integrates AndroPass, APKUtil, RMS and MobFS, providing a powerful tool for analyzing the security of Android applications. AndroPass is a tool that focuses on analyzing the security of Android applications' authentication and authorization mechanisms, while APKUtil is a tool that extracts valuable information from an APK file. Lastly, MobFS and RMS facilitates the analysis of an application's filesystem by mounting its storage in a virtual environment.
By combining these three tools, QuadraInspect provides a comprehensive approach to vulnerability analysis of Android applications. This framework can be used by developers, security researchers, and penetration testers to assess the security of their own or third-party applications. QuadraInspect provides a unified interface for all three tools, making it easier to use and reducing the time required to conduct comprehensive vulnerability analysis. Ultimately, this framework aims to increase the security of Android applications and protect users' sensitive data from potential threats.
To install the tools you need to: First : git clone https://github.com/morpheuslord/QuadraInspect
Second Open a Administrative cmd or powershell (for Mobfs setup) and run : pip install -r requirements.txt && python3 main.py
Third : Once QuadraInspect loads run this command QuadraInspect Main>> : START install_tools
The tools will be downloaded to the tools directory and also the setup.py and setup.bat commands will run automatically for the complete installation.
Each module has a help function so that the commands and the discriptions are detailed and can be altered for operation.
These are the key points that must be addressed for smooth working:
args or using SET target withing the tool.target folder as all the tool searches for the target file with that folder.There are 2 modes:
|
ββ> F mode
ββ> A mode
The f mode is a mode where you get the active interface for using the interactive vaerion of the framework with the prompt, etc.
F mode is the normal mode and can be used easily
A mode or argumentative mode takes the input via arguments and runs the commands without any intervention by the user this is limited to the main menu in the future i am planning to extend this feature to even the encorporated codes.
python main.py --target <APK_file> --mode a --command install_tools/tools_name/apkleaks/mobfs/rms/apkleaksthe main menu of the entire tool has these options and commands:
| Command | Discription |
|---|---|
SET target | SET the name of the targetfile |
START install_tools | If not installed this will install the tools |
LIST tools_name | List out the Tools Intigrated |
START apkleaks | Use APKLeaks tool |
START mobfs | Use MOBfs for dynamic and static analysis |
START andropass | Use AndroPass APK analizer |
help | Display help menu |
SHOW banner | Display banner |
quit | Quit the program |
As mentioned above the target must be set before any tool is used.
The APKLeaks menu is also really straight forward and only a few things to consider:
SET output and SET json-out takes file names not the actual files it creates an output in the result directory.SET pattern option takes a name of a json pattern file. The JSON file must be located in the pattern directory| OPTION | SET Value |
|---|---|
SET output | Output for the scan data file name |
SET arguments | Additional Disassembly arguments |
SET json-out | JSON output file name |
SET pattern | The pre-searching pattern for secrets |
help | Displays help menu |
return | Return to main menu |
quit | Quit the tool |
Mobfs is pritty straight forward only the port number must be taken care of which is by default on port 5000 you just need to start the program and connect to it on 127.0.0.1:5000 over your browser.
AndroPass is also really straight forward it just takes the file as input and does its job without any other inputs.
The APK analysis framework will follow a modular architecture, similar to Metasploit. It will consist of the following modules:
Currentluy there only 3 but if wanted people can add more tools to this these are the things to be considered:
config/installer.py
config/mobfs.py , config/androp.py, config/apkleaks.py
If wanted you could do your upgrades and add it to this repository for more people to use kind of growing this tool.
apk.sh is a Bash script that makes reverse engineering Android apps easier, automating some repetitive tasks like pulling, decoding, rebuilding and patching an APK.
apk.sh basically uses apktool to disassemble, decode and rebuild resources and some bash to automate the frida gadget injection process. It also supports app bundles/split APKs.
./apk.sh pull <package_name>
./apk.sh decode <apk_name>
./apk.sh build <apk_dir>
apk.sh pull pull an APK from a device. It supports app bundles/split APKs, which means that split APKs will be joined in a single APK (this is useful for patching). If the package is an app bundle/split APK, apk.sh will combine the APKs into a single APK, fixing all public resource identifiers.
apk.sh patch patch an APK to load frida-gadget.so on start.
frida-gadget.so is a Frida's shared library meant to be loaded by programs to be instrumented (when the Injected mode of operation isnβt suitable). By simply loading the library it will allow you to interact with it using existing Frida-based tools like frida-trace. It also supports a fully autonomous approach where it can run scripts off the filesystem without any outside communication.
Patching an APK is simple as running ./apk.sh patch <apk_name> --arch arm.
You can calso specify a Frida gadget configuration in a json ./apk.sh patch <apk_name> --arch arm --gadget-conf <config.json>
In the default interaction, Frida Gadget exposes a frida-server compatible interface, listening on localhost:27042 by default. In order to achieve early instrumentation Frida let Gadgetβs constructor function block until you either attach() to the process, or call resume() after going through the usual spawn() -> attach() -> ...apply instrumentation... steps.
If you donβt want this blocking behavior and want to let the program boot right up, or youβd prefer it listening on a different interface or port, you can customize this through a json configuration file.
The default configuration is:
{
"interaction": {
"type": "listen",
"address": "127.0.0.1",
"port": 27042,
"on_port_conflict": "fail",
"on_load": "wait"
}
}You can pass the gadget configuration file to apk.sh with the --gadget-conf option.
A typically suggested configuration might be:
{
"interaction": {
"type": "script",
"path": "/data/local/tmp/script.js",
"on_change":"reload"
}
}script.js could be something like:
var android_log_write = new NativeFunction(
Module.getExportByName(null, '__android_log_write'),
'int',
['int', 'pointer', 'pointer']
);
var tag = Memory.allocUtf8String("[frida-script][ax]");
var work = function() {
setTimeout(function() {
android_log_write(3, tag, Memory.allocUtf8String("ping @ " + Date.now()));
work();
}, 1000);
}
work();
android_log_write(3, tag, Memory.allocUtf8String(">--(O.o)-<"));adb push script.js /data/local/tmp
./apk.sh patch <apk_name> --arch arm --gadget-conf <config.json>
adb install file.gadget.apk
Add the following code to print to logcat the console.log output of any script from the frida codeshare when using the Script interaction type.
// print to logcat the console.log output
// see: https://github.com/frida/frida/issues/382
var android_log_write = new NativeFunction(
Module.getExportByName(null, '__android_log_write'),
'int',
['int', 'pointer', 'pointer']
);
var tag = Memory.allocUtf8String("[frida-script][ax]");
console.log = function(str) {
android_log_write(3, tag, Memory.allocUtf8String(str));
