Security Testing

Android & iOS security assessments aligned with OWASP MASVS — reverse engineering, runtime instrumentation, certificate pinning bypass, and local storage analysis.

Why It Matters

Mobile Apps Store More
Than Users Realize

Mobile applications frequently store authentication tokens, PII, and API credentials in insecure local storage — SharedPreferences, Keychain, SQLite, or plain files. They also communicate over APIs that assume the mobile client can be trusted.

Our researchers use the same tools real attackers use: Frida for runtime instrumentation, apktool and jadx for static analysis, Burp Suite with certificate pinning bypass, and custom PoC APKs to demonstrate real-world exploitation.

MASVS-STORAGE

Insecure data storage — SharedPreferences, SQLite, logs, backups, external storage, Keychain misconfiguration

MASVS-CRYPTO

Weak or hardcoded cryptographic keys, insecure algorithms, broken key management

MASVS-AUTH

Authentication flaws, session management, biometric bypass, token insecurity

MASVS-NETWORK

TLS validation, certificate pinning, cleartext traffic, network security config analysis

MASVS-PLATFORM

IPC vulnerabilities, exported components, deep links, WebView misconfigurations, JavaScript interfaces

MASVS-CODE

Hardcoded credentials, debug flags, obfuscation gaps, third-party SDK risks, binary protections

Methodology

Static + Dynamic Testing

Two complementary phases that together cover what neither achieves alone.

Phase 1 — Static Analysis

  • APK/IPA decompilation and source reconstruction (apktool, jadx, Ghidra)
  • Hardcoded secrets, API keys, credentials in source code and resources
  • AndroidManifest.xml / Info.plist security audit (exported components, permissions, debug flags)
  • Cryptographic implementation review — algorithms, key generation, storage
  • Third-party SDK and library vulnerability assessment
  • Network Security Config / ATS configuration analysis
  • Obfuscation and binary protection assessment

Phase 2 — Dynamic Analysis

  • Runtime instrumentation with Frida — function hooking, argument tampering, return value modification
  • Certificate pinning bypass (Frida scripts, Objection, custom patches)
  • Network traffic interception — Burp Suite proxy, TLS decryption
  • Local storage inspection — SharedPreferences, SQLite, Keychain, file system
  • IPC component testing — Activities, Services, Broadcast Receivers, Content Providers
  • Deep link and intent interception testing
  • Proof-of-concept APK/app construction for critical findings

What We Typically Find

Common vulnerabilities across real-world Android and iOS engagements.

Hardcoded API KeysHigh

Firebase, Google Maps, Stripe, and internal API keys embedded in resources or source code — readable by any attacker with the APK.

Insecure Token StorageHigh

JWT and session tokens stored in SharedPreferences or unencrypted SQLite — extractable without root on many devices.

Debuggable Production APKHigh

android:debuggable=true allows full ADB debugging, runtime code injection, and memory inspection on any USB-connected device.

Exported ComponentsMedium

Activities, Services, or Content Providers exported without proper authorization checks — accessible by other apps on the device.

WebView Code ExecutionHigh

Dangerous JavaScript interfaces, addJavascriptInterface misuse, or loading arbitrary URLs in WebViews enabling XSS-to-native escalation.

Cleartext Network TrafficMedium

Missing Network Security Config or usesCleartextTraffic=true enabling plaintext HTTP communication — interceptable on local networks.

Deliverables

Every mobile engagement produces a full technical report plus reproducible evidence.
