# Proxy Like a Pro: interesting method of proxying non proxy-aware Android Apps

In this blog post, we'll explore several methods to enable proxying for Android apps that do not natively support proxies. We'll cover regular methods like Wi-Fi settings, ADB commands, and Frida scripts, and then delve into more advanced techniques such as using iptables and DNS manipulation.

## Regular Methods to Enable Proxy

### 1\. Enabling Proxy in Wi-Fi Settings

One of the simplest ways to set up a proxy on an Android device is through the Wi-Fi settings.

1. Go to **Settings** > **Network & Internet** > **Wi-Fi**.
    
2. Long press on your Wi-Fi network and select **Modify network**.
    
3. Enable **Advanced options**.
    
4. Set **Proxy** to **Manual** and enter the proxy hostname and port.

### 2\. Using ADB Command

ADB (Android Debug Bridge) can be used to set a proxy for your Android device.

1. Connect your Android device to your computer.
    
2. Open a terminal and enter the following command:
    
    ```sh
    adb shell settings put global http_proxy <proxy_host>:<proxy_port>
    ```
    
3. To clear the proxy settings, use:
    
    ```sh
    adb shell settings put global http_proxy :0
    ```

### 3\. Proxy for an Individual App Using Frida Script or Objection Module

Frida and Objection can be used to hook into an app and force it to use a proxy.

#### Frida Script Example

1. Install Frida on your computer and device.
    
2. Write a Frida script to hook the app's network functions and redirect traffic through the proxy.
    
3. Execute the script while the app is running.
    

#### Objection Example

1. Install Objection and launch it against the target app:
    
    ```sh
    objection --gadget <app_package> explore
    ```
    
2. Use the following command within Objection:
    
    ```sh
    network monitor start --proxy <proxy_host>:<proxy_port>
    ```

## Advanced Method: Using iptables

### Setting Up iptables

Using iptables requires a rooted device. This method redirects all traffic through the proxy.

1. Gain root access on your device.
    
2. Use iptables to redirect traffic:
    
    ```sh
    iptables -t nat -A OUTPUT -p tcp --dport 80 -j DNAT --to-destination <proxy_host>:<proxy_port>
    iptables -t nat -A OUTPUT -p tcp --dport 443 -j DNAT --to-destination <proxy_host>:<proxy_port>
    ```
    
3. Verify that the traffic is being redirected.

## New approach: Proxy Using DNS

### 1\. Setting Up DNSChef

DNSChef can be used to redirect DNS requests to a proxy server.

1. Install DNSChef on your computer:
    
    ```sh
    pip install dnschef
    ```
    
2. Run DNSChef to redirect traffic:
    
    ```sh
    dnschef --fakeip <your_ip> --fakedomains <target_domain> 
    ```
    
    Alternatively, redirect all traffic:
    
    ```sh
    dnschef --fakeip <your_ip>
    ```

### 2\. Configuring Android DNS Settings

Configure your Android device to use the DNSChef server.

1. Go to **Settings** &gt; **Network & Internet** &gt; **Wi-Fi**.
    
2. Long press on your Wi-Fi network and select **Modify network**.
    
3. Enable **Advanced options**.
    
4. Set **IP settings** to **Static** and enter your computer's IP address as the DNS server.

### 3\. Enabling Transparent Proxy in Burp Suite

Finally, enable transparent proxying in Burp Suite to handle the incoming traffic.

1. Open Burp Suite and go to **Proxy** &gt; **Options**.
    
2. Add a new proxy listener and enable **Invisible proxying** under **Request Handling**.
