Android-InstallBurpCert

A Python 3 script that automates installing the Burp Suite CA certificate into an Android Emulator (AVD), enabling HTTPS traffic interception.

Requirements

• Python 3
• adb (Android Debug Bridge) in your PATH
• openssl in your PATH
• curl in your PATH
• Burp Suite running with its proxy listener on 127.0.0.1:8080
• An Android emulator started with a writable system image

Usage

1. Start the emulator with a writable system partition:

emulator @Pixel_2_XL_API_26 -writable-system -selinux disabled -no-audio -no-boot-anim

2. Start Burp Suite and ensure the proxy is listening on 127.0.0.1:8080.

3. Run the script:

python3 install-burpsuite-ca.py

What the Script Does

1. Verifies an emulator is connected via adb devices
2. Gains root access with adb root and remounts the system partition as writable
3. Downloads the Burp CA certificate from http://burp/cert through the proxy, converts it from DER to PEM, and renames it to the Android-expected hash filename (<hash>.0)
4. Pushes the certificate to /system/etc/security/cacerts/ with 644 permissions

Once complete, the emulator will trust Burp Suite's CA and HTTPS traffic can be intercepted transparently.

Tested On

• Android Emulator (AVD) — API 26 (Pixel 2 XL)
