Mobile Application Pentesting
This project focuses on penetration testing methodologies and tools for mobile applications. It covers security assessment techniques for both Android and iOS platforms.
Core Concepts
Mobile application pentesting assesses the security of an app, its on-device data, and its communication with backend services. Because the binary runs on a device the user (and attacker) fully controls, the goal is to find what trust the app misplaces in the client side.
Methodology / Phases:
- Recon and setup: obtain the build (APK/IPA), prepare a rooted/jailbroken device or emulator, and proxy traffic.
- Static analysis: decompile and review code, manifests, and resources for secrets, weak crypto, and exported components.
- Dynamic analysis: run the app, hook and instrument it (Frida/Objection), and observe runtime behavior.
- Network analysis: intercept API traffic and test for weak TLS, certificate pinning bypass, and insecure data in transit.
- Local storage review: inspect databases, preferences, keychain/keystore, logs, and cache for sensitive data.
Key Concepts / What to look for:
- Insecure data storage: credentials, tokens, or PII written in cleartext to device storage.
- Weak transport security: missing TLS validation or pinning that allows interception.
- Hardcoded secrets and weak cryptography embedded in the binary.
- Insecure platform usage: exported activities/services, intent issues, and improper permissions.
- Client-side trust: logic, authorization, or paywall checks enforced only on the device.

Prerequisites
- Basic understanding of security principles and mobile app architectures.
- Knowledge of Android and iOS platforms.
- Necessary tools and frameworks installed (see Tools section below).
Common Tests
- Static Analysis: Review source code and app binaries for vulnerabilities.
- Dynamic Analysis: Interact with the app and monitor its behavior in real time.
- Network Analysis: Inspect and modify network traffic between the app and backend services.
- Reverse Engineering: Decompile and analyze APK files to understand app logic and uncover potential security flaws.
