What Worries You About Your Android App?
Pick the one closest to your concern and see how we would test it.
Data Stored on the Device
Unencrypted sensitive data in SharedPreferences, SQLite databases or external storage.
Hijacked Sessions
Weak session management that allows session fixation or session hijacking.
Intercepted Traffic
Missing TLS/SSL or weak cipher suites that expose data in transit.
Injection Attacks
SQL injection, command injection and other input validation weaknesses.
Weak Authentication
Poor password policies, no multi-factor authentication or flawed login logic.
Reverse Engineering
Attackers decompiling your APK to find secrets, logic and weak controls.
Not sure where your app is weakest?
Our certified ethical hackers will help you decide what to test first.
Our Approach
At D2i Technology, we understand that each Android application is unique, requiring a tailored approach to security testing. Our team follows a systematic methodology to conduct thorough penetration testing, ensuring that no stone is left unturned. Here’s how we approach Android penetration testing:
Threat Modeling
We start by understanding your app's architecture, functionality and potential attack vectors so testing focuses on the most critical areas.
- Architecture
- Attack vectors
- Priorities
Static Analysis
Static code analysis finds insecure data storage, hardcoded credentials and improper input validation.
- Hardcoded secrets
- Storage
- Input validation
Dynamic Analysis
We assess behavior in real-world scenarios, including authentication bypass, session flaws and insecure communication.
- Auth bypass
- Sessions
- Traffic
Reverse Engineering
Reverse engineering techniques uncover hidden vulnerabilities and show the app's real security posture.
- Decompilation
- Hidden flaws
- Posture
Exploitation
In simulated attacks we exploit identified vulnerabilities to demonstrate their impact on your app.
- Attack simulation
- Proof of impact
- Risk rating
Reporting and Recommendations
A detailed report with prioritized remediation recommendations, plus guidance while you implement fixes.
- Prioritized fixes
- Guidance
- Re-test
