Intercepting Mobile Traffic with Burp Suite
When to Use
Use this skill when:
- Testing mobile application API endpoints for authentication, authorization, and injection vulnerabilities
- Analyzing data transmitted between mobile apps and backend servers during penetration tests
- Evaluating certificate pinning implementations and their bypass difficulty
- Identifying sensitive data leakage in mobile network traffic
Do not use this skill to intercept traffic from applications you are not authorized to test -- traffic interception without authorization violates computer fraud laws.
Prerequisites
- Burp Suite Professional or Community Edition installed on testing workstation
- Android device/emulator or iOS device on the same network as Burp Suite host
- Burp Suite CA certificate installed on the target device
- For Android 7+: Network security config modification or Magisk module for system CA trust
- For SSL pinning bypass: Frida + Objection or custom Frida scripts
- Wi-Fi network where proxy configuration is possible
Workflow
Step 1: Configure Burp Suite Proxy Listener
Burp Suite > Proxy > Options > Proxy Listeners:
- Bind to address: All interfaces (or specific IP)
- Bind to port: 8080
- Enable "Support invisible proxying"
Verify the listener is active and note the workstation's IP address on the shared network.
Step 2: Configure Mobile Device Proxy
Android:
Settings > Wi-Fi > [Network] > Advanced > Manual Proxy
- Host: <burp_workstation_ip>
- Port: 8080
iOS:
Settings > Wi-Fi > [Network] > Configure Proxy > Manual
- Server: <burp_workstation_ip>
- Port: 8080
Step 3: Install Burp Suite CA Certificate
Android (below API 24):
Android (API 24+ / Android 7+):
Apps targeting API 24+ do not trust user-installed CAs by default. Options:
openssl x509 -inform DER - burp-ca.der -out burp-ca.pem
HASH=$(openssl x509 -inform PEM -subject_hash_old - burp-ca.pem | -1)
burp-ca.pem
adb push /system/etc/security/cacerts/
adb shell 644 /system/etc/security/cacerts/.0
