JAMBOREE Android Security Sandbox Skill

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 integrates:

• Magisk: Systemless root and module management
• Burp Suite: HTTPS traffic interception and analysis
• Objection: Frida-powered runtime instrumentation
• Rooted Emulator: Pre-configured Android Virtual Devices

This skill enables AI agents to help developers configure, deploy, and use JAMBOREE for Android application security assessment, penetration testing, and reverse engineering.

Installation

Prerequisites Verification

Before deployment, verify the environment has required dependencies:

# Check Java version (JDK 11+)
java -version

# Verify Android SDK and platform tools
adb version
avdmanager list

# Confirm Python 3 for Objection
python3 --version

# Check Burp Suite installation
which burpsuite || echo "Burp Suite not found in PATH"

Core Installation Steps

1. Clone and Initialize

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

# Run environment validation
./orchestration/validators/check-prerequisites.sh

2. Deploy Core Components

./orchestration/calibrators/apply-config.sh custom

Configuration

Android Emulator Setup

Create or modify an AVD for security testing:

# List available system images
avdmanager list targets

# Create rooted AVD (x86_64, Android 13)
avdmanager create avd \
  -n jamboree-test \
  -k "system-images;android-33;google_apis_playstore;x86_64" \
  -d "pixel_5" \
  -c 4096M

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

# Wait for boot
adb wait-for-device
adb root
adb remount

Magisk Module Configuration

Deploy core modules for testing:

# Push Magisk Manager APK
adb install modules/magisk/MagiskManager.apk

# Install BusyBox module
adb push modules/magisk/systemless/busybox.zip /sdcard/
adb shell magisk --install-module /sdcard/busybox.zip

# Install certificate pinning bypass module
adb push modules/magisk/systemless/ssl-unpinning.zip /sdcard/
adb shell magisk --install-module /sdcard/ssl-unpinning.zip

# Reboot to apply
adb reboot
adb wait-for-device

Burp Suite Proxy Setup

Configure system-wide traffic interception:

# Generate and install Burp CA certificate
openssl x509 -inform DER -in burp-cert.der -out burp-cert.pem
CERT_HASH=$(openssl x509 -inform PEM -subject_hash_old -in burp-cert.pem | head -1)

# Push to system certificate store
adb root
adb remount
adb push burp-cert.pem /system/etc/security/cacerts/${CERT_HASH}.0
adb shell chmod 644 /system/etc/security/cacerts/${CERT_HASH}.0

# Configure proxy settings (Wi-Fi)
adb shell settings put global http_proxy ${BURP_HOST}:${BURP_PORT}

# Or use iptables redirection
adb shell iptables -t nat -A OUTPUT -p tcp --dport 80 -j DNAT --to-destination ${BURP_HOST}:${BURP_PORT}
adb shell iptables -t nat -A OUTPUT -p tcp --dport 443 -j DNAT --to-destination ${BURP_HOST}:${BURP_PORT}

Configuration file example (configurations/network/burp-proxy.conf):

[proxy]
host = 192.168.1.100
port = 8080
upstream_proxy = 
cert_path = ./modules/burp/certificates/burp-ca.pem

[interception]
mode = transparent
dns_spoofing = true
ssl_passthrough = false

[filters]
include_hosts = *.example.com,*.target-app.io
exclude_hosts = *.google.com,*.android.com

Objection Environment

Install and configure Objection with Frida:

# Install Objection via pip
pip3 install objection

# Install Frida server on device
FRIDA_VERSION=$(frida --version)
wget https://github.com/frida/frida/releases/download/${FRIDA_VERSION}/frida-server-${FRIDA_VERSION}-android-x86_64.xz
unxz frida-server-${FRIDA_VERSION}-android-x86_64.xz

adb push frida-server-${FRIDA_VERSION}-android-x86_64 /data/local/tmp/frida-server
adb shell "chmod 755 /data/local/tmp/frida-server"
adb shell "/data/local/tmp/frida-server &"

Key Commands and Workflows

Basic Application Analysis

# List installed packages
adb shell pm list packages | grep -i target

# Get package information
adb shell dumpsys package com.example.targetapp

# Pull APK for static analysis
adb shell pm path com.example.targetapp
adb pull /data/app/~~random~~/com.example.targetapp-hash==/base.apk

Objection Runtime Hooking

Launch Objection against a running app:

# Spawn app with Objection
objection -g com.example.targetapp explore

# Or attach to running process
objection -g $(adb shell pidof com.example.targetapp) explore

Common Objection commands in the interactive shell:

// List activities and classes
android hooking list activities
android hooking list classes

// Search for methods
android hooking search methods encrypt
android hooking search classes database

// Hook method and print arguments
android hooking watch class_method com.example.crypto.AES.encrypt --dump-args --dump-return

// Bypass root detection
android root disable

// Bypass SSL pinning
android sslpinning disable

// Explore SQLite databases
sqlite connect /data/data/com.example.targetapp/databases/app.db
.tables
SELECT * FROM users;

// Dump SharedPreferences
android hooking list shared_preferences
android hooking get shared_preference com.example.targetapp_preferences

// Memory operations
memory dump all com.example.targetapp
memory search "password" --string

Advanced Frida Scripts

Custom hooking scripts in modules/objection/scripts/:

hook-crypto.js - Monitor cryptographic operations:

Java.perform(function() {
    var Cipher = Java.use('javax.crypto.Cipher');
    
    Cipher.doFinal.overload('[B').implementation = function(input) {
        console.log('[Cipher.doFinal] Input length: ' + input.length);
        console.log('[Cipher.doFinal] Input hex: ' + bytesToHex(input));
        
        var result = this.doFinal(input);
        
        console.log('[Cipher.doFinal] Output length: ' + result.length);
        console.log('[Cipher.doFinal] Output hex: ' + bytesToHex(result));
        
        return result;
    };
    
    function bytesToHex(bytes) {
        var hex = [];
        for (var i = 0; i < bytes.length && i < 32; i++) {
            hex.push(('0' + (bytes[i] & 0xFF).toString(16)).slice(-2));
        }
        return hex.join(' ') + (bytes.length > 32 ? '...' : '');
    }
    
    console.log('[+] Cipher.doFinal hooked');
});

bypass-root-check.js - Defeat root detection:

Java.perform(function() {
    var RootDetection = Java.use('com.example.security.RootDetection');
    
    RootDetection.isRooted.implementation = function() {
        console.log('[Root Detection] Bypass triggered');
        return false;
    };
    
    RootDetection.checkSuperUser.implementation = function() {
        console.log('[Root Detection] SuperUser check bypassed');
        return false;
    };
    
    RootDetection.checkBuildTags.implementation = function() {
        console.log('[Root Detection] Build tags check bypassed');
        return false;
    };
    
    console.log('[+] Root detection bypassed');
});

Load custom scripts:

# Via Objection
objection -g com.example.targetapp explore -s modules/objection/scripts/hook-crypto.js

# Via Frida directly
frida -U -l modules/objection/scripts/bypass-root-check.js -f com.example.targetapp

Burp Suite Automation

Extend Burp with Python extensions in modules/burp/extensions/:

auto-scanner.py - Automated endpoint discovery:

from burp import IBurpExtender, IHttpListener, ITab
from javax.swing import JPanel, JTextArea, JScrollPane
import json

class BurpExtender(IBurpExtender, IHttpListener, ITab):
    def registerExtenderCallbacks(self, callbacks):
        self._callbacks = callbacks
        self._helpers = callbacks.getHelpers()
        callbacks.setExtensionName("JAMBOREE Auto Scanner")
        
        self.endpoints = set()
        self.setup_ui()
        
        callbacks.registerHttpListener(self)
        
    def processHttpMessage(self, toolFlag, messageIsRequest, messageInfo):
        if not messageIsRequest:
            return
            
        request = messageInfo.getRequest()
        analyzedRequest = self._helpers.analyzeRequest(messageInfo)
        
        url = analyzedRequest.getUrl()
        endpoint = f"{url.getProtocol()}://{url.getHost()}{url.getPath()}"
        
        if endpoint not in self.endpoints:
            self.endpoints.add(endpoint)
            self.update_display()
            
    def setup_ui(self):
        self.panel = JPanel()
        self.textarea = JTextArea(20, 80)
        self.textarea.setEditable(False)
        scrollPane = JScrollPane(self.textarea)
        self.panel.add(scrollPane)
        
        self._callbacks.addSuiteTab(self)
        
    def update_display(self):
        output = "\n".join(sorted(self.endpoints))
        self.textarea.setText(f"Discovered Endpoints ({len(self.endpoints)}):\n\n{output}")
        
    def getTabCaption(self):
        return "JAMBOREE Scanner"
        
    def getUiComponent(self):
        return self.panel

Traffic Analysis Workflow

Complete workflow for intercepting and analyzing app traffic:

# 1. Start Frida server
adb shell "/data/local/tmp/frida-server &"

# 2. Launch Burp Suite
burpsuite --proxy-port=${BURP_PORT} &

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

# 4. Disable SSL pinning with Objection
objection -g com.example.targetapp explore <<EOF
android sslpinning disable
exit
EOF

# 5. Launch app
adb shell am start -n com.example.targetapp/.MainActivity

# 6. Monitor traffic in Burp and extract patterns
# Burp Suite captures all HTTP/HTTPS traffic automatically

# 7. Export findings
# From Burp: Proxy > HTTP History > Save items

Common Patterns

Pattern 1: API Endpoint Discovery and Analysis

#!/bin/bash
# discover-apis.sh

PACKAGE=$1
DURATION=${2:-300}  # 5 minutes default

echo "[+] Starting API discovery for ${PACKAGE}"

# Start network capture
adb shell tcpdump -i any -w /sdcard/capture.pcap &
TCPDUMP_PID=$!

# Launch app with Objection hooks
objection -g ${PACKAGE} explore <<EOF
android hooking watch class_method okhttp3.OkHttpClient.newCall --dump-args --dump-return
android hooking watch class_method retrofit2.Retrofit.create --dump-args
exit
EOF &

# Wait for specified duration
sleep ${DURATION}

# Stop capture
kill ${TCPDUMP_PID}
adb pull /sdcard/capture.pcap ./analysis/

# Parse with tshark
tshark -r ./analysis/capture.pcap -Y "http || tls" -T fields \
  -e http.request.full_uri \
  -e tls.handshake.extensions_server_name | sort -u > ./analysis/endpoints.txt

echo "[+] Discovered $(wc -l < ./analysis/endpoints.txt) unique endpoints"
cat ./analysis/endpoints.txt

Pattern 2: Database Extraction and Analysis

#!/bin/bash
# extract-databases.sh

PACKAGE=$1
OUTPUT_DIR="./databases/${PACKAGE}"

mkdir -p ${OUTPUT_DIR}

# Find all SQLite databases
adb shell "run-as ${PACKAGE} find /data/data/${PACKAGE} -name '*.db'" | while read DB_PATH; do
    DB_NAME=$(basename ${DB_PATH})
    
    echo "[+] Extracting ${DB_NAME}"
    
    # Copy to accessible location
    adb shell "run-as ${PACKAGE} cp ${DB_PATH} /sdcard/${DB_NAME}"
    adb pull /sdcard/${DB_NAME} ${OUTPUT_DIR}/
    
    # Analyze schema
    sqlite3 ${OUTPUT_DIR}/${DB_NAME} ".schema" > ${OUTPUT_DIR}/${DB_NAME}.schema.sql
    
    # Dump data
    sqlite3 ${OUTPUT_DIR}/${DB_NAME} ".dump" > ${OUTPUT_DIR}/${DB_NAME}.dump.sql
    
    echo "[+] ${DB_NAME}: $(sqlite3 ${OUTPUT_DIR}/${DB_NAME} 'SELECT COUNT(*) FROM sqlite_master WHERE type=\"table\"') tables"
done

Pattern 3: Automated Certificate Pinning Bypass

Create a persistent bypass module:

// modules/objection/scripts/persistent-ssl-bypass.js

Java.perform(function() {
    console.log('[+] Loading persistent SSL bypass');
    
    // OkHttp3 CertificatePinner
    try {
        var CertificatePinner = Java.use('okhttp3.CertificatePinner');
        CertificatePinner.check.overload('java.lang.String', 'java.util.List').implementation = function() {
            console.log('[SSL] OkHttp3 pinning bypassed for: ' + arguments[0]);
        };
    } catch(e) {}
    
    // TrustManager bypass
    try {
        var X509TrustManager = Java.use('javax.net.ssl.X509TrustManager');
        var SSLContext = Java.use('javax.net.ssl.SSLContext');
        
        var TrustManager = Java.registerClass({
            name: 'com.jamboree.TrustManager',
            implements: [X509TrustManager],
            methods: {
                checkClientTrusted: function(chain, authType) {},
                checkServerTrusted: function(chain, authType) {},
                getAcceptedIssuers: function() { return []; }
            }
        });
        
        var TrustManagers = [TrustManager.$new()];
        var SSLContext_init = SSLContext.init.overload(
            '[Ljavax.net.ssl.KeyManager;',
            '[Ljavax.net.ssl.TrustManager;',
            'java.security.SecureRandom'
        );
        
        SSLContext_init.implementation = function(keyManager, trustManager, secureRandom) {
            console.log('[SSL] SSLContext.init hooked');
            SSLContext_init.call(this, keyManager, TrustManagers, secureRandom);
        };
    } catch(e) {}
    
    // Universal Android SSL bypass
    try {
        var SSLContext = Java.use('javax.net.ssl.SSLContext');
        var TrustManager = Java.registerClass({
            name: 'com.jamboree.UniversalTrust',
            implements: [Java.use('javax.net.ssl.X509TrustManager')],
            methods: {
                checkClientTrusted: function() {},
                checkServerTrusted: function() {},
                getAcceptedIssuers: function() { return []; }
            }
        });
        
        SSLContext.getDefault.implementation = function() {
            var context = SSLContext.getInstance('TLS');
            context.init(null, [TrustManager.$new()], null);
            return context;
        };
    } catch(e) {}
    
    console.log('[+] SSL bypass hooks installed');
});

Deploy automatically on app launch:

# Add to ~/.frida/scripts/
mkdir -p ~/.frida/scripts
cp modules/objection/scripts/persistent-ssl-bypass.js ~/.frida/scripts/

# Create wrapper
cat > ~/bin/jamboree-launch <<'EOF'
#!/bin/bash
PACKAGE=$1
frida -U -l ~/.frida/scripts/persistent-ssl-bypass.js -f ${PACKAGE} --no-pause
EOF

chmod +x ~/bin/jamboree-launch

Troubleshooting

Issue: Certificate Not Trusted

Symptoms: HTTPS traffic not captured, SSL errors in app

Solution:

# Verify certificate installation
adb shell ls -la /system/etc/security/cacerts/ | grep -i burp

# Check certificate hash matches filename
openssl x509 -inform PEM -subject_hash_old -in burp-cert.pem | head -1

# Force reinstall
adb root && adb remount
CERT_HASH=$(openssl x509 -inform PEM -subject_hash_old -in burp-cert.pem | head -1)
adb push burp-cert.pem /system/etc/security/cacerts/${CERT_HASH}.0
adb shell chmod 644 /system/etc/security/cacerts/${CERT_HASH}.0
adb reboot

Issue: Frida Connection Failed

Symptoms: Failed to spawn: unable to find process with name 'com.example.app'

Solution:

# Check Frida server is running
adb shell "ps -A | grep frida"

# Restart Frida server
adb shell "killall frida-server"
adb shell "/data/local/tmp/frida-server &"

# Verify Frida version compatibility
frida --version
adb shell "/data/local/tmp/frida-server --version"

# If versions mismatch, download matching server version

Issue: Magisk Module Not Loading

Symptoms: Module shows as installed but features not working

Solution:

# Check module status
adb shell magisk --list

# View Magisk logs
adb shell cat /cache/magisk.log

# Reinstall in recovery mode
adb reboot recovery
# Use volume keys to navigate to "Install" > Select module ZIP

# Check for conflicts
adb shell magisk --remove-module conflicting-module
adb reboot

Issue: Objection Hooks Not Triggering

Symptoms: Hooks installed but no output when methods called

Solution:

// Verify class/method exists first
Java.perform(function() {
    // List all classes matching pattern
    Java.enumerateLoadedClasses({
        onMatch: function(className) {
            if (className.indexOf('example') !== -1) {
                console.log('[+] Found: ' + className);
                
                // List methods
                var clazz = Java.use(className);
                var methods = clazz.class.getDeclaredMethods();
                methods.forEach(function(method) {
                    console.log('  -> ' + method);
                });
            }
        },
        onComplete: function() {}
    });
});

Issue: Emulator Detection

Symptoms: App exits or shows warning about running on emulator

Solution:

# Modify build.prop to mimic real device
adb root && adb remount
adb shell "cat >> /system/build.prop <<EOF
ro.product.manufacturer=samsung
ro.product.model=SM-G991B
ro.product.brand=samsung
ro.build.fingerprint=samsung/o1sxxx/o1s:13/TP1A.220624.014/G991BXXU5DVLB:user/release-keys
EOF"

# Hide Magisk from detection
adb shell magisk --denylist add com.example.targetapp

# Use Shamiko module for advanced hiding
adb push modules/magisk/systemless/shamiko.zip /sdcard/
adb shell magisk --install-module /sdcard/shamiko.zip

adb reboot

Environment Variables

JAMBOREE uses these environment variables:

# Burp Suite configuration
export BURP_HOST="192.168.1.100"
export BURP_PORT="8080"
export BURP_CERT_PATH="./modules/burp/certificates/burp-ca.pem"

# Android configuration
export ANDROID_SDK_ROOT="${HOME}/Android/Sdk"
export ANDROID_AVD_HOME="${HOME}/.android/avd"

# Frida/Objection
export FRIDA_SERVER_PATH="/data/local/tmp/frida-server"

# Logging
export JAMBOREE_LOG_LEVEL="DEBUG"  # DEBUG, INFO, WARN, ERROR
export JAMBOREE_LOG_PATH="./logs/jamboree.log"

Best Practices

1. Always work in isolated environments - Use dedicated emulators or test devices
2. Document findings - Keep detailed logs of hooks, modified traffic, and discovered vulnerabilities
3. Version control configurations - Track changes to Frida scripts and Burp extensions
4. Regular updates - Keep Magisk, Frida, and Objection current for compatibility
5. Test incrementally - Apply one bypass at a time to identify what works
6. Backup emulator snapshots - Save working configurations before major changes
