Mobile Application Testing
iOS and Android application security testing aligned to OWASP MASVS standards.
Mobile Application Security Testing
Mobile apps operate in a fundamentally hostile environment: devices are jailbroken or rooted, network traffic is intercepted, and binaries are decompiled by anyone with a laptop and free tools. Intelliroot's Mobile Application Security Testing service delivers a rigorous, OWASP MASVS-aligned assessment across both iOS and Android platforms, covering static code analysis, dynamic runtime testing, and adversarial instrumentation using Frida and Objection. We test the app itself, its back-end API communication, and local data storage — holistically, the way a real attacker would.
Our CREST-certified mobile security engineers hold deep expertise across the full stack of mobile attack techniques: defeating certificate pinning, extracting secrets from Keychain and SharedPreferences, abusing deep links and intent handling, intercepting and modifying runtime method calls, and reverse-engineering obfuscated code. Whether your app processes payments, health records, or enterprise data, we give you a precise, evidence-backed view of your mobile risk posture and a clear path to remediation before your next app store release.
Why Mobile Security Testing Is Critical
The Device Is Not Trusted Territory
Users run your app on rooted phones, install certificate trust stores, and use traffic interception proxies. Security controls that assume a trusted device are trivially defeated — your app must be hardened assuming adversarial conditions.
Insecure Local Storage Is Epidemic
Credentials, tokens, PII, and cryptographic keys stored insecurely in SQLite databases, plists, or SharedPreferences are recoverable by any attacker with physical or malware-level access. This is one of the most common and impactful findings across all mobile assessments.
Deep Links and Intent Hijacking
Improperly validated deep links and Android intents allow malicious apps to invoke sensitive functionality, steal OAuth tokens mid-flow, or redirect users to phishing pages — often without any visible indicator to the user.
Runtime Manipulation Bypasses All Static Controls
Tools like Frida allow attackers to hook any function at runtime — bypassing biometric checks, root detection, certificate pinning, and licence validation without modifying the binary. Only runtime-aware testing can validate that these controls hold under adversarial conditions.
What We Test
Static Analysis (SAST)
- Reverse engineering and decompilation (APK / IPA)
- Hardcoded credentials, API keys, and secrets in code
- Insecure cryptographic implementations
- Exported components and permission misconfigurations (Android)
- Insecure URL schemes and deep link handling
Dynamic Analysis (DAST)
- Certificate pinning bypass and traffic interception
- Session token analysis and management weaknesses
- Back-end API security (OWASP API Top 10)
- Authentication bypass and biometric control evasion
- Sensitive data in transit (TLS downgrade, weak ciphers)
Local Data Storage & OS Interaction
- Keychain / Keystore usage and access controls
- SQLite, SharedPreferences, and plist sensitive data exposure
- Clipboard exposure of sensitive values
- Screenshot caching and app switcher data leakage
- Log file exposure of tokens and PII
Runtime Manipulation & Instrumentation
- Frida and Objection-based method hooking
- Root and jailbreak detection bypass
- Anti-tampering and integrity check evasion
- OTA update mechanism security (binary authenticity)
- Third-party SDK security review
Our Approach
Scoping & Threat Modelling
We review your app's architecture, data classification, and threat model to prioritise the highest-risk areas. We agree on test accounts, back-end environments, and any functionality that should be excluded (e.g., live payment gateways) before testing begins.
Static Analysis & Reverse Engineering
The application binary is decompiled and analysed using Jadx, Ghidra, class-dump, and custom scripts. We search for hardcoded secrets, insecure API calls, exported components, and cryptographic misuse embedded in the application code.
Environment Setup & Certificate Pinning Bypass
We configure a test device (rooted Android or jailbroken iOS) and establish full network visibility using Burp Suite with certificate pinning bypass via Frida scripts. This allows complete inspection of all back-end API communication in its true, runtime form.
Dynamic Testing & API Assessment
With traffic interception established, we perform comprehensive dynamic testing of all app functionality — manipulating API requests, testing authorisation controls, and attempting business logic abuse across every workflow the app exposes.
Runtime Instrumentation
Using Frida and Objection, our engineers hook into the application at runtime to bypass security controls, intercept cryptographic operations, dump decrypted data, and test the resilience of root detection, anti-tampering, and biometric authentication controls.
Reporting & Developer Debrief
We deliver a comprehensive report with OWASP MASVS mapping, CVSS 3.1 scores, and step-by-step reproduction evidence. A live debrief session with your development team translates findings into a practical remediation sprint and answers implementation questions directly.
