# Frida Intercept Encrypted Api
[](https://github.com/noobpk/frida-ios-intercept-api/actions/workflows/codeql-analysis.yml)
## 📍What does it help?
Banking applications, e-wallets, .. are increasingly enhanced security to fight hackers. One of them is to encrypt request/response data when sending and receiving. Some weak encryptions can be decrypted easily, but some strong encryptions like RSA are difficult.
When pentesting a normal mobile application, we just need to set it up so that BurpSuite can intercept the request / response of the APIs that the application uses. But when pentesting a banking or e-wallet application with end-to-end encrypted API, with the usual BurpSuite setup we cannot see the content of the API.
Hooking into functions that send request/response and intercept data before it is encrypted is one way we can view and modify data.
## Architecture
## For IOS
### Configurage ios_handlers.js
1. Add your Request / Response Class & Method
```
/*Request Class & Method*/
var search_request_class = [''];
var search_request_method = [''];
/*Response Class & Method*/
var search_response_class = [''];
var search_response_method = [''];`
```
2. Debug ARGS in Class & Method
```
/*DEBUG REQUEST HERE*/
console.log(colors.green,"[DEBUG-REQUEST] Dump Arugment in method: ",colors.resetColor);
print_arguments(args);
```
## For Android
### Configurage android_handlers.js
1. Add your Request / Response Class & Method
```
/*Request Class & Method*/
var request_class = Java.use('');
var request_method = '';
/*Response Class & Method*/
var response_class = Java.use('');
var response_method = '';
```
## Usage
1. Load `burpsuite_configuration_proxy.json` or Set up Burpsuite Proxy by following the steps below
- Listen on 127.0.0.1:26080
- Redirect to 127.0.0.1:27080 and Check (Support invisible proxying)
1. Run echoServer.py
1. Config and optimize `_handlers.js`
1. Run burpTracer.py -p com.apple.AppStore / [-n 'App Store']
`Note: Different applications will use different libraries. You need to reverse or trace the application to find the correct function.`
