2. Create Custom Modules:
- Write your own Xposed modules to hook specific functions in Android apps.
- For example, create a module that logs when a user inputs sensitive data like a password or PIN.

---

### Step 6: Reporting Findings

- Log Results: Document all hooks and modifications made during the testing process. This can help in creating a detailed report on vulnerabilities such as insecure data handling, poor encryption, or API flaws.
- Create Exploits: Automate exploit generation using custom modules for repeated tests on similar vulnerabilities.

---

### Ethical Considerations
- Always ensure you have explicit permission to test any app.
- Use Xposed responsibly for ethical hacking and security research only.

🦑 Xposed Framework, a powerful tool for Android customization and hacking. Xposed allows you to modify system and app behavior without modifying APKs, making it a great tool for penetration testers and security researchers.

## Xposed Framework Hacking Tutorial

Xposed Framework is a tool for Android devices that allows you to modify system-level behavior and individual apps at runtime. It provides hooks that enable you to change app behavior, bypass protections, or test for vulnerabilities.

### Prerequisites
1. Rooted Android Device:
To use Xposed, your device needs to be rooted. Tools like Magisk or SuperSU can be used for rooting.

2. Install Xposed Framework:
- Download the Xposed Installer APK from [Xposed's official site](https://repo.xposed.info/).
- Install the APK on your rooted Android device.

3. Install Xposed Modules:
Modules are what allow Xposed to hook into apps and change their behavior.
- Popular modules for security testing include:
- App Settings (to modify app permissions and behavior).
- XPrivacyLua (for manipulating app permissions).
- Substrate (for advanced hooking capabilities).

---

### Step 1: Basic Setup

1. Enable Xposed Framework:
Once installed, open the Xposed Installer app. Enable the framework and reboot your device.

2. Install Modules:
After enabling the framework, go to the "Download" section in the Xposed Installer, search for modules like XPrivacyLua (for privacy manipulation) or App Settings (to change app settings), and install them.

---

### Step 2: Analyzing an App

1. Hooking into an App:
- Open the Xposed Installer and go to the Modules tab.
- Enable the App Settings or XPrivacyLua module, and configure the hooks to manipulate or bypass app behavior.

2. Modify App Permissions:
- Use XPrivacyLua to deny apps specific permissions like camera, location, SMS, or contacts.
- For example, you can stop apps from sending sensitive data over the network.

3. Bypass SSL Pinning:
- If an app uses SSL pinning to prevent certificate manipulation, use Xposed SSL Unpinning modules.
- These modules hook into the SSL connection code and allow interception of SSL traffic.

---

### Step 3: Exploiting Vulnerabilities

1. Test for Hardcoded Credentials:
- You can use App Settings to modify app behavior dynamically and check if apps have hardcoded credentials or perform insecure operations.
- Modify app functions at runtime to bypass authentication and access restricted parts of the app.

2. Bypass Root Detection:
- Many apps detect whether they are running on a rooted device and block access if they find out. You can use RootCloak or similar modules to bypass this check.

3. Monitor Network Traffic:
- Use Burp Suite in conjunction with Xposed to inspect and modify network traffic.
- Set up a proxy on your device, intercept requests, and look for vulnerabilities like insecure data transmission or exposed API keys.

---

### Step 4: Advanced Hooking

1. Hook System Methods:
Xposed allows you to hook into system functions. For example:

   XposedBridge.hookAllMethods(Class.forName("android.app.Activity"), "onPause", new XC_MethodHook() {
       @Override
       protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
           Log.d("Xposed", "Activity is pausing: " + param.method.getName());
       }
   });
   

This example hooks into the onPause method of all activities to log when any activity is paused. You can customize hooks for specific methods based on your analysis.

2. Manipulate the UI:
Modify the app’s UI behavior, such as bypassing confirmation dialogs or manipulating elements, by hooking UI-related methods.

---

### Step 5: Testing and Debugging

1. Use Xposed for Debugging:
- Monitor method calls and function behavior in real time using logging or a custom debug module.
- Example: Intercept a method that retrieves sensitive information and log it to the console for further analysis.

🦑 Tool: Gobuster - Directory and File Brute Forcing

Gobuster is a tool used for brute forcing directories and files on web servers, often used to discover hidden resources and files that could be vulnerable.

---

### Basic Usage Command:

gobuster dir -u http://example.com -w /path/to/wordlist.txt

Explanation:
- gobuster: Runs the Gobuster tool.
- dir: Specifies the mode to brute-force directories and files.
- -u http://example.com: The target URL to scan.
- -w /path/to/wordlist.txt: Specifies the path to a wordlist that contains potential directory and file names.

---

### Example: Brute Force with Status Code Filtering

gobuster dir -u http://example.com -w /path/to/wordlist.txt -s "200,301"

Explanation:
- -s "200,301": Filters results to only show directories and files that return HTTP status codes 200 (OK) and 301 (Moved Permanently), indicating valid paths.

---

### Example: Brute Force Subdomains

gobuster dns -d example.com -w /path/to/subdomains.txt

Explanation:
- dns: Specifies the mode to brute-force subdomains.
- -d example.com: The domain to search for subdomains.
- -w /path/to/subdomains.txt: Path to a wordlist containing possible subdomains.

---

### Example: Using Custom User-Agent

gobuster dir -u http://example.com -w /path/to/wordlist.txt -H "User-Agent: CustomAgent"

Explanation:
- -H "User-Agent: CustomAgent": Specifies a custom user-agent to avoid detection or bypass certain filters.

---

### Example: Using Multiple Threads

gobuster dir -u http://example.com -w /path/to/wordlist.txt -t 50

Explanation:
- -t 50: Sets the number of concurrent threads to 50, speeding up the brute-forcing process.

---

### Important Notes:
1. Gobuster is mainly used in penetration testing and security research.
2. Always obtain permission before using Gobuster for brute-forcing directories, files, or subdomains. Unauthorized testing can result in legal consequences.
