Mobile Application
Security Testing

Mobile apps sit on your users' devices, in environments you don't control. We test iOS and Android apps the way a motivated attacker would: reversing binaries, intercepting traffic, cracking local storage, and probing your backend APIs.

iOS, Android & Hybrid

Native Swift/Kotlin, React Native, Flutter, Xamarin. We test the app regardless of how it was built.

Static, dynamic & runtime analysis

We decompile the binary, intercept live traffic, and test runtime behaviour. Three angles of attack, not just one.

OWASP MASVS Aligned

Tested against the Mobile Application Security Verification Standard. The most recognised mobile security framework.

Mobile Security Matters

Your mobile app handles logins, payments, personal data, things users trust you with. A vulnerability in how the app stores tokens, communicates with your backend, or handles sessions can turn that trust into a breach headline.

Mobile is a different beast from web. The app runs on someone else's device. The binary can be decompiled. Local storage can be read. Traffic can be intercepted with a $0 proxy. Your testers need to think about all of that, not just OWASP Top 10 for web.

If your app touches money, health data, or personal information, it needs more than a scan. It needs someone trying to break it the way a real attacker would on a jailbroken device, with a proxy running, looking at every request.

Our Testing Approach

We follow OWASP MASVS as our framework, but the real testing goes beyond any checklist. We attack the app from three angles: static analysis of the binary, dynamic testing at runtime, and inspection of everything stored on the device.

Static Analysis (SAST)

We decompile your APK or IPA and dig through the code looking for hardcoded API keys, weak crypto implementations, embedded secrets, and logic that shouldn't be in the client. If it's in the binary, we'll find it.

Binary decompilation and code review
Hardcoded credentials and API keys
Insecure data storage patterns
Dynamic Analysis (DAST)

Dynamic Analysis (DAST)

We run the app on real and emulated devices, proxy all traffic, and watch what happens, how it talks to the backend, what data it sends in the clear, and how it behaves when things go wrong (expired tokens, tampered responses, interrupted sessions).

Runtime manipulation and hooking (Frida/Objection)
Network traffic interception
API endpoint fuzzing

Local Data Storage Testing

We examine everything the app writes to disk. SQLite databases, SharedPreferences/NSUserDefaults, the Keychain/Keystore, cache directories, logs, and temp files. If your app stores a token, password, or PII locally, we check whether it's encrypted and how.

SQLite database encryption
Keychain/Keystore security
Sensitive data in logs and caches

Key Security Areas

Insecure Data Storage
Weak Cryptography
Insecure Authentication
Insufficient Transport Layer Protection
Insecure Authorization
Deeplink & URL Scheme Hijacking
Code Tampering
Reverse Engineering
WebView Security Issues
Debug/Test Code in Production Builds
Obfuscation & Tamper Detection
Anti-Debugging Controls
Session Management Flaws

Platform-Specific Testing

iOS Security Testing

iOS Security Testing

iOS has strong built-in security. Keychain, ATS, code signing, but misconfiguration and misuse are common. We test how your app actually uses these mechanisms, not just whether they exist.

Keychain security implementation
Certificate pinning validation
App Transport Security (ATS)
Touch ID / Face ID Bypass
URL scheme hijacking
Jailbreak detection bypass

Android Security Testing

Android's open ecosystem and component-based architecture create unique attack surfaces. Exported activities, unprotected content providers, insecure WebViews, and weak root detection. We test all of it.

Android Keystore usage
Certificate pinning implementation
Content provider security
Intent redirection vulnerabilities
WebView security issues
Root detection bypass

What You Receive

Detailed Security Report

Every vulnerability documented with screenshots, device/OS details, reproduction steps, and severity ratings. Organized so your mobile dev team can start fixing without a walkthrough call.

Binary Analysis Report

Results from decompiling and reviewing the app binary. Hardcoded secrets, embedded API keys, insecure crypto usage, and any sensitive logic exposed in the client.

Remediation Guide

iOS and Android-specific fix guidance with code examples on how to properly implement Keychain storage, certificate pinning, biometric auth, and other platform security features

Executive Summary

A plain-English overview for stakeholders. What was tested, what's at risk, and what to prioritise. Written for people who need to make budget decisions, not read exploit code.

Mobile App Vulnerabilities Are Costly

Most mobile apps ship with at least a few security issues. Insecure storage, weak certificate handling, or hardcoded keys hiding in the binary. The question isn't whether vulnerabilities exist. It's whether you find them before someone else does.

Your app is on millions of devices. Make sure it's not leaking data from every one of them.
