Android App Penetration Testing
Your APK is one decompile away from revealing everything.
Static + dynamic analysis using OWASP MSTG, Frida, and real-device testing.

What Gets Tested
Two-phase approach: static analysis of the decompiled APK followed by dynamic runtime analysis on a real device. Backend API security is included — mobile apps and their servers are tested as a system, not in isolation.
// Static Analysis
- Hardcoded credentials, API keys & secrets
- Insecure data storage (SharedPreferences, SQLite, logs)
- Exported activities, services & broadcast receivers
- Improper permissions & permission abuse
- Insecure file access & content providers
- Weak cryptographic implementations
- Third-party SDK risks
// Dynamic Analysis
- SSL pinning bypass & certificate validation
- Traffic interception & man-in-the-middle testing
- Runtime method hooking with Frida
- Webview security & JavaScript bridge abuse
- Debuggable app & backup abuse
- Root detection bypass
- Backend API abuse from mobile context
Methodology: OWASP Mobile Security Testing Guide (MSTG). Tools: Frida, Jadx, MobSF, Burp Suite, ADB, drozer.
Who Benefits Most
Mobile apps handle sensitive data on devices you don't control. That's a different risk model — and it needs dedicated testing.
Mobile-First Startups
Your entire product lives on the phone. Insecure local storage or a hardcoded API key in the APK is a critical risk from day one.
Fintech & Payments
Apps handling transactions, account access, or card data — where a bypass of authentication or SSL pinning has immediate financial impact.
Healthcare & MedTech
Apps storing or transmitting health records — where local data exposure or API abuse violates compliance requirements, not just user trust.
Pre-App Store Launch
Before you ship to 100,000 users, find out what a motivated attacker would find in your APK with tools freely available to anyone.
Post-Bug Bounty Report
A researcher submitted something via HackerOne and you want a full review to understand the actual scope of the issue.
Enterprise MDM Apps
Internal apps deployed via MDM that handle corporate data — tested before rollout to the whole company.
What You Receive
A report your mobile dev team can act on — covering both the APK and backend findings, with reproduction steps and remediation that maps to Android-specific APIs and patterns.
- Executive summary for stakeholders
- Static analysis findings with decompiled code references
- Dynamic testing findings with screen/Frida evidence
- Risk-ranked across OWASP MSTG categories
- Backend API findings included in the same report
- Android-specific remediation guidance
- Findings walkthrough call with your team
- Free retest to verify fixes are solid

Serious Testing. Startup-Friendly Pricing.
Android testing covers both static and dynamic analysis phases plus backend API coverage. The depth is thorough; the price is designed to be accessible for product teams who know security matters before launch — not after an incident.
Starting from
Final price quoted after a free scoping call. Everything below is always included.
What's always included
- Full static APK analysis
- Dynamic runtime testing on real device
- SSL pinning bypass & traffic inspection
- Backend API security included
- OWASP MSTG-aligned report
- Free retest of confirmed fixes
What affects the final price
You send me the APK — no need to share store credentials or release the app publicly. Testing happens on a dedicated test device in a controlled environment.
Common Questions
Do I need to share source code or just the APK?
The APK alone is sufficient — I decompile it as an attacker would. If you can share source code, I'll use it to confirm findings and get more depth on the logic layer, but it's never a requirement. Grey-box testing (APK + docs + test account) typically produces the most findings for the cost.
Does this cover the app's backend API too?
Yes — backend API testing is included in every Android engagement. You can't properly test a mobile app without testing what it talks to. API findings are documented in the same report alongside the on-device findings.
What if our app uses SSL pinning or root detection?
I bypass both as part of the standard dynamic analysis phase — that's the whole point. SSL pinning exists to prevent traffic inspection, but a determined attacker will bypass it, so I test from that perspective. Frida is my primary runtime tool for this.
Do you test iOS apps too?
Not currently — Android is my specialization. If you need iOS testing, I can point you toward a trusted contact or scope a combined engagement if there's enough Android work to anchor it.
