Android Mobile Security Sandbox JAMBOREE

Skill by ara.so — Security Skills collection

Overview

JAMBOREE (Java Android Magisk Burp Objection Root Emulator Easy) is a unified Android security testing framework that orchestrates multiple tools into a cohesive pentesting environment. It automates the integration of:

• Magisk modules for systemless root and module management
• Burp Suite proxy for traffic interception and certificate handling
• Objection/Frida for runtime instrumentation and hooking
• Rooted Android emulators optimized for security testing

This framework eliminates fragmented workflows by providing pre-configured components that work together seamlessly for Android application security assessment.

Installation

Prerequisites

Ensure the following are installed:

# Java Development Kit 11+
java -version

# Android SDK with platform tools
which adb

# Python 3.8+ for Objection
python3 --version

# Frida tools
pip3 install frida-tools objection

Framework Setup

# Clone the repository
git clone https://github.com/hero-mike/Android-Mobile-Security-Sandbox-Testing.git
cd Android-Mobile-Security-Sandbox-Testing

# Run the orchestration script
chmod +x orchestration/deploy.sh
./orchestration/deploy.sh

# Verify installation
./orchestration/validate.sh

The deployment script will:

1. Validate dependencies
2. Configure Android emulator with Magisk
3. Install Burp Suite CA certificates
4. Deploy Objection scripts and Frida gadgets
5. Set up proxy routing

Core Components

1. Magisk Module Management

# Install Magisk modules
adb push modules/magisk/systemless/universal-safetynet-fix.zip /sdcard/
adb shell su -c "magisk --install-module /sdcard/universal-safetynet-fix.zip"

# List installed modules
adb shell su -c "ls /data/adb/modules"

# Enable/disable module
adb shell su -c "touch /data/adb/modules/module-name/disable"
adb reboot

# Remove module
adb shell su -c "rm -rf /data/adb/modules/module-name"

Custom Module Installation:

# Deploy custom init.d script
adb push configurations/android/custom-init.sh /data/adb/service.d/
adb shell su -c "chmod 755 /data/adb/service.d/custom-init.sh"

2. Burp Suite Integration

Certificate Installation:

# Export Burp CA certificate (DER format)
# In Burp: Proxy → Options → Import/Export CA certificate

# Convert to PEM and get hash
openssl x509 -inform DER -in burp-ca.der -out burp-ca.pem
CERT_HASH=$(openssl x509 -inform PEM -subject_hash_old -in burp-ca.pem | head -1)

# Install as system certificate
adb root
adb remount
adb push burp-ca.pem /system/etc/security/cacerts/${CERT_HASH}.0
adb shell chmod 644 /system/etc/security/cacerts/${CERT_HASH}.0
adb reboot

Proxy Configuration:

# Set system-wide proxy
adb shell settings put global http_proxy <HOST_IP>:8080

# Or use the provided configuration script
./orchestration/deployers/burp-proxy-setup.sh --host 192.168.1.100 --port 8080

# Verify proxy settings
adb shell settings get global http_proxy

# Clear proxy
adb shell settings put global http_proxy :0

VPN-based Interception:

# Install proxy VPN app
adb install modules/burp/proxy-vpn.apk

# Configure VPN tunnel
adb shell am start -n com.proxyvpn/.MainActivity \
  --es PROXY_HOST "192.168.1.100" \
  --ei PROXY_PORT 8080

3. Objection Runtime Instrumentation

Basic Objection Usage:

# List running apps
frida-ps -Ua

# Attach to running app
objection -g com.example.target explore

# Spawn app with Objection
objection -g com.example.target run

SSL Pinning Bypass:

# Inside Objection REPL
android sslpinning disable

# Or using custom script
objection -g com.example.target explore \
  -s "android sslpinning disable" \
  -s "jobs list"

Common Objection Commands:

// List activities
android hooking list activities

// List classes
android hooking list classes

// Search for methods
android hooking search methods decrypt

// Hook specific method
android hooking watch class_method com.example.Crypto.decrypt --dump-args --dump-return

// Bypass root detection
android root disable

// List shared preferences
android file shared-preferences list

// Read specific preference
android file shared-preferences read com.example.target.prefs user_token

// SQLite operations
android sqlite list
android sqlite query /data/data/com.example.target/databases/main.db "SELECT * FROM users"

// Dump memory
memory dump all /tmp/memory-dump.bin

// Export class definitions
android hooking dump class com.example.target.MainActivity

Custom Frida Scripts:

Create hooks/ssl-bypass.js:

Java.perform(function() {
    console.log("[*] SSL Pinning Bypass Active");
    
    // Hook OkHttp3 Certificate Pinner
    var CertificatePinner = Java.use("okhttp3.CertificatePinner");
    CertificatePinner.check.overload('java.lang.String', 'java.util.List').implementation = function() {
        console.log("[+] Bypassed OkHttp3 Certificate Pinner");
    };
    
    // Hook TrustManagerImpl
    var TrustManagerImpl = Java.use("com.android.org.conscrypt.TrustManagerImpl");
    TrustManagerImpl.verifyChain.implementation = function(untrustedChain, trustAnchorChain, host, clientAuth, ocspData, tlsSctData) {
        console.log("[+] Bypassed TrustManagerImpl verification for: " + host);
        return untrustedChain;
    };
    
    // Hook SSLContext
    var SSLContext = Java.use("javax.net.ssl.SSLContext");
    SSLContext.init.overload('[Ljavax.net.ssl.KeyManager;', '[Ljavax.net.ssl.TrustManager;', 'java.security.SecureRandom').implementation = function(keyManager, trustManager, secureRandom) {
        console.log("[+] SSLContext.init() called, accepting all certificates");
        this.init.overload('[Ljavax.net.ssl.KeyManager;', '[Ljavax.net.ssl.TrustManager;', 'java.security.SecureRandom').call(this, keyManager, null, secureRandom);
    };
});

Load custom script:

# Using Frida directly
frida -U -l hooks/ssl-bypass.js -f com.example.target

# Using Objection with custom script
objection -g com.example.target explore --startup-script hooks/ssl-bypass.js

Method Hooking Template:

Java.perform(function() {
    var TargetClass = Java.use("com.example.target.Crypto");
    
    // Hook encryption method
    TargetClass.encrypt.implementation = function(plaintext, key) {
        console.log("[*] Encrypt called");
        console.log("[*] Plaintext: " + plaintext);
        console.log("[*] Key: " + key);
        
        var result = this.encrypt(plaintext, key);
        console.log("[*] Encrypted result: " + result);
        
        return result;
    };
    
    // Hook with multiple overloads
    TargetClass.processData.overload('java.lang.String').implementation = function(data) {
        console.log("[*] processData(String) called with: " + data);
        return this.processData(data);
    };
    
    TargetClass.processData.overload('[B').implementation = function(data) {
        console.log("[*] processData(byte[]) called");
        return this.processData(data);
    };
});

4. Emulator Configuration

Create Rooted AVD:

# Using provided configuration
./orchestration/deployers/create-rooted-avd.sh \
  --name jamboree-test \
  --api 30 \
  --arch x86_64

# Manual AVD creation
avdmanager create avd \
  -n security-test \
  -k "system-images;android-30;google_apis;x86_64" \
  -d "pixel_4"

# Start emulator with writable system
emulator -avd security-test -writable-system -no-snapshot-load &

# Wait for boot
adb wait-for-device

# Install Magisk
adb install modules/magisk/Magisk-v26.1.apk

Anti-Emulation Evasion:

# Modify build properties
adb shell su -c "mount -o rw,remount /system"
adb shell su -c "echo 'ro.build.fingerprint=google/redfin/redfin:11/RQ3A.211001.001/7641976:user/release-keys' >> /system/build.prop"
adb shell su -c "echo 'ro.product.manufacturer=Google' >> /system/build.prop"
adb reboot

# Hide emulator artifacts
adb shell su -c "setprop ro.kernel.qemu 0"
adb shell su -c "setprop ro.hardware.goldfish 0"

Workflow Patterns

Complete Penetration Test Setup

#!/bin/bash
# setup-pentest.sh

TARGET_PACKAGE="com.example.target"
BURP_HOST="192.168.1.100"
BURP_PORT="8080"

echo "[*] Starting JAMBOREE penetration test environment"

# 1. Start emulator
emulator -avd jamboree-test -writable-system -no-snapshot-load &
adb wait-for-device
sleep 10

# 2. Configure proxy
adb shell settings put global http_proxy ${BURP_HOST}:${BURP_PORT}

# 3. Verify Magisk root
adb shell su -c "id" || { echo "[!] Root not available"; exit 1; }

# 4. Install target app
adb install -r target-app.apk

# 5. Start Objection with SSL bypass
objection -g ${TARGET_PACKAGE} explore \
  --startup-script hooks/ssl-bypass.js &

echo "[+] Environment ready. Burp Suite should show traffic."

Automated Hook Deployment

# deploy_hooks.py
import frida
import sys

HOOKS = {
    "crypto": """
Java.perform(function() {
    var Cipher = Java.use("javax.crypto.Cipher");
    Cipher.doFinal.overload('[B').implementation = function(data) {
        console.log("[Cipher] doFinal called with " + data.length + " bytes");
        return this.doFinal(data);
    };
});
""",
    "network": """
Java.perform(function() {
    var URL = Java.use("java.net.URL");
    URL.$init.overload('java.lang.String').implementation = function(url) {
        console.log("[Network] URL requested: " + url);
        return this.$init(url);
    };
});
"""
}

def attach_hooks(package_name, hook_type):
    device = frida.get_usb_device()
    pid = device.spawn([package_name])
    session = device.attach(pid)
    
    script = session.create_script(HOOKS[hook_type])
    script.on('message', lambda msg, data: print(msg))
    script.load()
    
    device.resume(pid)
    print(f"[+] {hook_type} hooks attached to {package_name}")
    sys.stdin.read()

if __name__ == "__main__":
    attach_hooks(sys.argv[1], sys.argv[2])

Usage:

python3 deploy_hooks.py com.example.target crypto

Traffic Analysis Workflow

# 1. Clear app data
adb shell pm clear com.example.target

# 2. Start packet capture
adb shell su -c "tcpdump -i wlan0 -w /sdcard/capture.pcap" &

# 3. Start Burp Suite listener on port 8080

# 4. Launch app with Objection
objection -g com.example.target explore \
  -s "android sslpinning disable" \
  -s "android root disable"

# 5. Perform actions in app

# 6. Stop capture and retrieve
adb shell su -c "killall tcpdump"
adb pull /sdcard/capture.pcap ./analysis/

Configuration Files

Burp Suite Extension Config

configurations/burp/extension-config.json:

{
  "proxy": {
    "enabled": true,
    "host": "0.0.0.0",
    "port": 8080,
    "ssl": {
      "generateCert": true,
      "certPath": "/certificates/burp-ca.pem"
    }
  },
  "interceptRules": [
    {
      "match": ".*\\.api\\.example\\.com.*",
      "action": "intercept",
      "modifyHeaders": {
        "User-Agent": "CustomAgent/1.0"
      }
    }
  ],
  "bypassSSL": true
}

Objection Startup Scripts

configurations/objection/startup.js:

// Auto-load common bypasses
android sslpinning disable;
android root disable;

// Custom hooks
android hooking watch class_method com.example.target.Auth.login --dump-args --dump-return;
android hooking watch class_method com.example.target.Network.makeRequest --dump-args --dump-return;

// Monitor file operations
android hooking watch class java.io.FileOutputStream.$init --dump-args;

console.log("[JAMBOREE] Startup hooks loaded");

Load on startup:

objection -g com.example.target explore --startup-script configurations/objection/startup.js

Troubleshooting

Certificate Trust Issues

Symptom: HTTPS traffic not decrypted in Burp Suite

Solutions:

# 1. Verify certificate installation
adb shell ls -la /system/etc/security/cacerts/ | grep $(openssl x509 -inform PEM -subject_hash_old -in burp-ca.pem | head -1)

# 2. Check certificate format (must be PEM with .0 extension)
openssl x509 -in /system/etc/security/cacerts/9a5ba575.0 -text -noout

# 3. Ensure correct permissions
adb shell su -c "chmod 644 /system/etc/security/cacerts/*.0"

# 4. For Android 14+, use Magisk module
adb push modules/magisk/movecert.zip /sdcard/
adb shell su -c "magisk --install-module /sdcard/movecert.zip"
adb reboot

Frida/Objection Connection Failures

Symptom: Failed to spawn: unable to find application with identifier

Solutions:

# 1. Verify Frida server version matches client
frida --version
adb shell /data/local/tmp/frida-server --version

# 2. Update Frida server
wget https://github.com/frida/frida/releases/download/$(frida --version)/frida-server-$(frida --version)-android-x86_64.xz
unxz frida-server-*.xz
adb push frida-server-* /data/local/tmp/frida-server
adb shell su -c "chmod 755 /data/local/tmp/frida-server"
adb shell su -c "/data/local/tmp/frida-server &"

# 3. Check if app is debuggable
adb shell pm dump com.example.target | grep -A 1 "debuggable"

# 4. Force debuggable mode (requires repackaging)
apktool d target.apk
# Edit AndroidManifest.xml: android:debuggable="true"
apktool b target -o target-debug.apk
jarsigner -keystore debug.keystore target-debug.apk androiddebugkey
adb install target-debug.apk

Magisk Module Conflicts

Symptom: Device bootloop or modules not loading

Solutions:

# 1. Boot to safe mode (hold volume down during boot)
# Then remove problematic modules via Magisk Manager

# 2. Via ADB (if accessible)
adb shell su -c "touch /data/adb/modules/problem-module/disable"
adb reboot

# 3. Complete module reset
adb shell su -c "rm -rf /data/adb/modules/*"
adb reboot

# 4. Check module logs
adb shell su -c "cat /cache/magisk.log"

Proxy Not Routing Traffic

Symptom: No requests appearing in Burp Suite

Solutions:

# 1. Verify proxy settings
adb shell settings get global http_proxy

# 2. Test connectivity
adb shell curl -x http://192.168.1.100:8080 http://example.com

# 3. Check iptables rules
adb shell su -c "iptables -t nat -L -n -v"

# 4. Force proxy via iptables redirect
adb shell su -c "iptables -t nat -A OUTPUT -p tcp --dport 80 -j DNAT --to-destination 192.168.1.100:8080"
adb shell su -c "iptables -t nat -A OUTPUT -p tcp --dport 443 -j DNAT --to-destination 192.168.1.100:8080"

# 5. Use VPN-based proxy as fallback
adb install modules/burp/drony.apk
# Configure Drony to redirect all traffic to Burp

Advanced Techniques

Custom Magisk Module Creation

#!/system/bin/sh
# modules/magisk/custom-bypass/service.sh

MODDIR=${0%/*}

# Disable root detection checks
resetprop ro.debuggable 0
resetprop ro.secure 1

# Hide Magisk from SafetyNet
magiskhide enable
magiskhide add com.example.target

# Custom file redirects
mount -o bind $MODDIR/system/lib/libc.so /system/lib/libc.so

log -p i -t JAMBOREE "Custom bypass module loaded"

Module metadata (module.prop):

id=jamboree-custom-bypass
name=JAMBOREE Custom Bypass
version=1.0
versionCode=1
author=YourName
description=Custom root and emulator detection bypass

Install:

cd modules/magisk/custom-bypass
zip -r custom-bypass.zip .
adb push custom-bypass.zip /sdcard/
adb shell su -c "magisk --install-module /sdcard/custom-bypass.zip"
adb reboot

Runtime Memory Manipulation

// hooks/memory-dump.js
Java.perform(function() {
    var String = Java.use("java.lang.String");
    var token = null;
    
    // Hook authentication token storage
    var SharedPreferences = Java.use("android.content.SharedPreferences");
    var Editor = Java.use("android.content.SharedPreferences$Editor");
    
    Editor.putString.implementation = function(key, value) {
        if (key.indexOf("token") !== -1 || key.indexOf("auth") !== -1) {
            console.log("[*] Token stored: " + key + " = " + value);
            token = value;
            
            // Dump to file
            var File = Java.use("java.io.File");
            var FileWriter = Java.use("java.io.FileWriter");
            var file = File.$new("/sdcard/extracted-token.txt");
            var writer = FileWriter.$new(file);
            writer.write(value);
            writer.close();
        }
        return this.putString(key, value);
    };
});
