Mobile Audit- SAST And Malware Analysis lab setup For Android APKs.
Django Web application for performing Static Analysis and detecting malware in Android APKs
Malware Analysis lab setup
In each of the scans, it would have the following information for Malware Analysis lab setup:
- Application Info
- Security Info
- Components
- SAST Findings
- Best Practices Implemented
- Virus Total Info
- Certificate Info
- Strings
- Databases
- Files
For easy access there is a sidebar on the left page of the scan: Malware Analysis lab setup

Patterns
The application has an engine with different rules and patterns that are used though the findings scanning phase to detect vulnerabilities and/or malicious code into the apk.
These can be activated and deactivated in /patterns
Note: some of the hardcoded patterns are from apkleaks
Models
The application has an created models for each of the entities of the scans’ information to be able to create relations an abtain the best conclusions for each of the apks.
To see the whole model schema, go to models
Integrations
Virus Total (API v3)
It checks if there has been an scan of the APK and extract all its information. Also, there is the possibility of uploading the APK is selected a property in the environment (Disabled by default).
Defect Dojo (API v2)
It is possible to upload the findings to the defect manager.
MalwareDB & Maltrail
It checks in the database if there are URLs in the APK that are related with Malware.
Installation
Using Docker-compose:
The provided docker-compose.yml file allows you to run the app locally in development.
To build the local image and if there are changes to the local Application Dockerfile, you can build the image with:
docker-compose build
Then, to start the container, run:
docker-compose up
Optional: run in detached mode (not see the logs)
docker-compose up -d
Once the application has launched, you can test the application by navigating to:
http://localhost:8888/ to access the dashboard.
Also, there is a TLS version using docker-compose.prod.yaml running in port 443
To use it, execute
docker-compose -f docker-compose.prod.yaml up
Then, you can test the application by navigating to: https://localhost/ to access the dashboard.
To stop and remove the containers, run
docker-compose down
API v1
REST API integration with Swagger and ReDoc.
Usage
Endpoint to authenticate and get token: /api/v1/auth-token/
Once authenticated, use header in all requests: Authorization: Token Swagger
Swagger
Endpoints
- A JSON view of the API specification at /swagger.json
- A YAML view of the API specification at /swagger.yaml
- A swagger-ui view of the API specification at /swagger/
- A ReDoc view of the API specification at /redoc/
TLS
Pre-requirements
- Add the certificates into nginx/ssl
- To generate a self-signed certificate:
openssl req -x509 -nodes -days 1 -newkey rsa:4096 -subj "/C=ES/ST=Madrid/L=Madrid/O=Example/OU=IT/CN=localhost" -keyout nginx/ssl/nginx.key -out nginx/ssl/nginx.crt
Nginx configuration
- TLS – port 443: nginx/app_tls.conf
- Standard – port 8888: nginx/app.conf
Docker configuration
By default, there is a volume in docker-compose.yml with the configuration with 8888 available.
./nginx/app.conf:/etc/nginx/conf.d/app.conf
In production environment** use docker-compose.prod.yaml with port 443
./nginx/app_tls.conf:/etc/nginx/conf.d/app_tls.conf
Environment variables
All the environment variables are in a .env file, there is an .env.example with all the variables needed. Also there are collected in app/config/settings.py:
