Mobile Pentesting
Mobile penetration testing (pentesting) is the process of assessing the security of mobile applications and devices by simulating real-world attacks. It identifies vulnerabilities in app code, APIs, data storage, and network communications. Pentesters use static and dynamic analysis, reverse engineering, and exploitation techniques to uncover security flaws. The goal is to strengthen app security, prevent data breaches.
In the world of cyber espionage, you are known as "Shadow," a legendary hacker-for-hire. Your reputation for breaching high-security systems has made you the top choice for secretive clients. This time, an underground entity known as "The Black Fox" has approached you with an urgent mission: infiltrate a high-security Android application network suspected of holding classified intelligence.
Mission Objective:
The target is a corporation known for its advanced Android application security. Their latest app contains hidden vulnerabilities, and your task is to uncover them using the most sophisticated tools available. You must analyze, decompile, and manipulate the app to expose its weaknesses, gaining access to the classified data within.
Mission Breakdown:
1. Establish Communication – Before anything else, you need a tool to establish a connection with the Android device, allowing remote control and data retrieval.
2. Source Code Analysis – To find weaknesses, you must perform a static analysis of the application's source code, searching for vulnerabilities.
3. Exploiting Components – Some applications expose vulnerable exported components that can be exploited. You need a specialized tool to test and exploit these weaknesses.
4. Decompilation & File Analysis – To understand how the app works internally, you must decompile the APK and examine its files.
5. Automated Security Scanning – Time is of the essence. You need an automation tool to quickly scan the Android application for security flaws.
6. Cloud Storage Enumeration – The application may be linked to cloud storage. Your task is to enumerate and expose any unprotected cloud storage buckets.
7. APK Signing and Verification – To modify and repackage the app, you need a tool to generate and manage keys for signing the APK.
8. Signing the APK – Once modified, the APK must be signed using common tools before it can be installed and tested.
9. Dynamic Analysis & Injection – To manipulate the app’s behavior, you must use a tool for dynamic analysis and script injection.
10. Network Traffic Analysis – To uncover sensitive data transmission, you must use a tool to capture and analyze network traffic from the app.
By completing these steps, you will have mapped the app’s weaknesses and uncovered hidden data pathways. Successfully overcoming all 10 challenges will grant you full access to the corporation’s classified database—delivering The Black Fox the secrets they seek.
Are you ready? The infiltration begins now.
A mysterious app, Craw Xport, has surfaced with potential vulnerabilities. Your mission is to infiltrate its system, exploit weaknesses, and retrieve classified data.
Your first task is to identify the package name of the app, the key to accessing its internal structure. Once found, locate the data directory, where sensitive files may be hidden. As you dig deeper, you uncover a critical flaw—an exported activity, a backdoor that could be exploited. Using tools like Drozer, execute an attack to retrieve the hidden flag and log your success.
But the app holds more secrets. A hardcoded flag hash is buried within its code, encrypted using techniques like Base64, SHA-256, or XOR. Decode it to uncover the real flag. Further investigation reveals a hardcoded password hash, hinting at insecure credential storage. Crack the password and extract it.
To complete your mission, analyze the app’s TargetSDK and MinSDK to assess its security level. Finally, examine its APK signature to reveal the Organization Unit (OU) behind its development.
