## Instalacja
|
|
|
|
Zainstaluj **narzędzia Frida**:
|
|
```bash
|
|
pip install frida-tools
|
|
pip install frida
|
|
```
|
|
**Pobierz i zainstaluj** na urządzeniu Android **serwer Frida** ([Pobierz najnowsze wydanie](https://github.com/frida/frida/releases)).\
|
|
Jednolinijkowe polecenie do ponownego uruchomienia adb w trybie root, połączenia z nim, przesłania frida-server, nadania uprawnień do wykonania i uruchomienia go w tle:
|
|
|
|
{% code overflow="wrap" %}
|
|
```bash
|
|
adb root; adb connect localhost:6000; sleep 1; adb push frida-server /data/local/tmp/; adb shell "chmod 755 /data/local/tmp/frida-server"; adb shell "/data/local/tmp/frida-server &"
|
|
```
|
|
{% endcode %}
|
|
|
|
**Sprawdź**, czy to **działa**:
|
|
```bash
|
|
frida-ps -U #List packages and processes
|
|
frida-ps -U | grep -i <part_of_the_package_name> #Get all the package name
|
|
```

# Hook java `exit()`
|
|
|
|
## Introduction
|
|
|
|
In this tutorial, we will learn how to hook the `exit()` method in Java using Frida. By hooking this method, we can intercept the application's exit calls and perform additional actions before the application terminates.
|
|
|
|
## Prerequisites
|
|
|
|
Before we begin, make sure you have the following:
|
|
|
|
- A rooted Android device or an emulator
|
|
- Frida installed on your machine
|
|
- Basic knowledge of JavaScript and Java
|
|
|
|
## Steps
|
|
|
|
Follow these steps to hook the `exit()` method:
|
|
|
|
1. Launch the target application on your Android device or emulator.
|
|
|
|
2. Open a terminal and start the Frida server by running the following command:
|
|
|
|
```bash
|
|
frida-server
|
|
```
|
|
|
|
3. Create a new JavaScript file, for example `hook_exit.js`, and add the following code:
|
|
|
|
```javascript
|
|
Java.perform(function() {
|
|
var System = Java.use('java.lang.System');
|
|
var Runtime = Java.use('java.lang.Runtime');
|
|
|
|
// Hook the exit() method of System class
|
|
System.exit.implementation = function(code) {
|
|
console.log('System.exit() called with code: ' + code);
|
|
|
|
// Perform additional actions here
|
|
|
|
// Call the original exit() method
|
|
this.exit(code);
|
|
};
|
|
|
|
// Hook the exit() method of Runtime class
|
|
Runtime.getRuntime().exit.implementation = function(code) {
|
|
console.log('Runtime.exit() called with code: ' + code);
|
|
|
|
// Perform additional actions here
|
|
|
|
// Call the original exit() method
|
|
this.exit(code);
|
|
};
|
|
});
|
|
```
|
|
|
|
4. Save the JavaScript file.
|
|
|
|
5. In the terminal, navigate to the directory where the JavaScript file is saved.
|
|
|
|
6. Use Frida to inject the JavaScript code into the target application by running the following command:
|
|
|
|
```bash
|
|
frida -U -l hook_exit.js -f <package_name>
|
|
```
|
|
|
|
Replace `<package_name>` with the package name of the target application.
|
|
|
|
7. You should see the output of the `console.log()` statements in the terminal whenever the `exit()` method is called.
|
|
|
|
8. Customize the additional actions in the JavaScript code as per your requirements.
|
|
|
|
## Conclusion
|
|
|
|
By hooking the `exit()` method in Java using Frida, we can intercept the application's exit calls and perform additional actions before the application terminates. This technique can be useful for various purposes, such as debugging, analyzing application behavior, or modifying the application's flow.
|
|
```javascript
|
|
var sysexit = Java.use("java.lang.System");
|
|
sysexit.exit.overload("int").implementation = function(var_0) {
|
|
send("java.lang.System.exit(I)V // We avoid exiting the application :)");
|
|
};
|
|
```

# Frida Tutorial: Hook MainActivity `.onStart()` & `.onCreate()`
|
|
|
|
W tym samouczku dowiesz się, jak używać Fridy do przechwytywania wywołań metod `.onStart()` i `.onCreate()` w klasie MainActivity w aplikacji Androidowej.
|
|
|
|
## Wymagania
|
|
|
|
Aby zacząć, musisz mieć zainstalowane następujące narzędzia:
|
|
|
|
- [Frida](https://frida.re/docs/installation/)
|
|
- [Android Studio](https://developer.android.com/studio)
|
|
|
|
## Kroki
|
|
|
|
1. Sklonuj repozytorium z przykładową aplikacją Androidową:
|
|
|
|
```
|
|
git clone https://github.com/example/example-app.git
|
|
```
|
|
|
|
2. Otwórz projekt w Android Studio i zbuduj go.
|
|
|
|
3. Uruchom aplikację na urządzeniu lub emulatorze.
|
|
|
|
4. Uruchom Fridę w trybie serwera na swoim komputerze:
|
|
|
|
```
|
|
frida-server
|
|
```
|
|
|
|
5. Uruchom skrypt Fridy, który przechwytuje wywołania metod `.onStart()` i `.onCreate()` w klasie MainActivity:
|
|
|
|
```javascript
|
|
Java.perform(function () {
|
|
var MainActivity = Java.use('com.example.app.MainActivity');
|
|
|
|
MainActivity.onStart.implementation = function () {
|
|
console.log('Hooked MainActivity.onStart()');
|
|
this.onStart();
|
|
};
|
|
|
|
MainActivity.onCreate.implementation = function (savedInstanceState) {
|
|
console.log('Hooked MainActivity.onCreate()');
|
|
this.onCreate(savedInstanceState);
|
|
};
|
|
});
|
|
```
|
|
|
|
6. Podłącz się do urządzenia/emulatora za pomocą Fridy:
|
|
|
|
```
|
|
frida -U com.example.app -l script.js
|
|
```
|
|
|
|
7. Teraz, gdy aplikacja zostanie uruchomiona, zobaczysz w konsoli wiadomości potwierdzające, że metody `.onStart()` i `.onCreate()` zostały przechwycone.
|
|
|
|
## Podsumowanie
|
|
|
|
Dzięki Fridzie możesz łatwo przechwytywać wywołania metod w aplikacjach Androidowych. W tym samouczku nauczyłeś się, jak przechwycić metody `.onStart()` i `.onCreate()` w klasie MainActivity.
|
|
```javascript
|
|
var mainactivity = Java.use("sg.vantagepoint.uncrackable1.MainActivity");
|
|
mainactivity.onStart.overload().implementation = function() {
|
|
send("MainActivity.onStart() HIT!!!");
|
|
var ret = this.onStart.overload().call(this);
|
|
};
|
|
mainactivity.onCreate.overload("android.os.Bundle").implementation = function(var_0) {
|
|
send("MainActivity.onCreate() HIT!!!");
|
|
var ret = this.onCreate.overload("android.os.Bundle").call(this,var_0);
|
|
};
|
|
```

# Hook android `.onCreate()`
|
|
|
|
## Introduction
|
|
|
|
In this tutorial, we will learn how to hook the `.onCreate()` method in an Android application using Frida. By hooking this method, we can intercept and modify the behavior of the application during its initialization process.
|
|
|
|
## Prerequisites
|
|
|
|
Before we begin, make sure you have the following:
|
|
|
|
- A rooted Android device or an emulator
|
|
- Frida installed on your machine
|
|
- Basic knowledge of JavaScript and Android development
|
|
|
|
## Steps
|
|
|
|
1. Start by launching the target application on your device or emulator.
|
|
|
|
2. Open a terminal and run the following command to start the Frida server:
|
|
|
|
```bash
|
|
frida-server
|
|
```
|
|
|
|
3. Next, we need to find the process ID (PID) of the target application. Run the following command to list all running processes:
|
|
|
|
```bash
|
|
frida-ps -U
|
|
```
|
|
|
|
Look for the process corresponding to the target application and note down its PID.
|
|
|
|
4. Now, create a new JavaScript file (e.g., `hook.js`) and add the following code:
|
|
|
|
```javascript
|
|
Java.perform(function() {
|
|
var targetClass = Java.use('com.example.TargetClass');
|
|
targetClass.onCreate.implementation = function() {
|
|
console.log('onCreate() hooked');
|
|
// Add your custom code here
|
|
this.onCreate();
|
|
};
|
|
});
|
|
```
|
|
|
|
Replace `com.example.TargetClass` with the actual class name of the target application.
|
|
|
|
5. Save the `hook.js` file and run the following command to start the hooking process:
|
|
|
|
```bash
|
|
frida -U -l hook.js -p <PID>
|
|
```
|
|
|
|
Replace `<PID>` with the PID of the target application obtained in step 3.
|
|
|
|
6. If everything is set up correctly, you should see the message `onCreate() hooked` in the Frida console.
|
|
|
|
7. Now, whenever the target application's `.onCreate()` method is called, your custom code will be executed.
|
|
|
|
## Conclusion
|
|
|
|
By hooking the `.onCreate()` method in an Android application using Frida, you can gain control over the application's initialization process and modify its behavior as desired. This technique can be useful for various purposes, such as bypassing security checks or analyzing the application's internal workings.
|
|
```javascript
|
|
var activity = Java.use("android.app.Activity");
|
|
activity.onCreate.overload("android.os.Bundle").implementation = function(var_0) {
|
|
send("Activity HIT!!!");
|
|
var ret = this.onCreate.overload("android.os.Bundle").call(this,var_0);
|
|
};
|
|
```
|
|
### Hookowanie funkcji z parametrami i pobieranie wartości
|
|
|
|
Hookowanie funkcji deszyfrującej. Wyświetl wejście, wywołaj oryginalną funkcję, odszyfruj dane wejściowe i na koniec wyświetl odszyfrowane dane:
|
|
```javascript
|
|
function getString(data){
|
|
var ret = "";
|
|
for (var i=0; i < data.length; i++){
|
|
ret += data[i].toString();
|
|
}
|
|
return ret
|
|
}
|
|
var aes_decrypt = Java.use("sg.vantagepoint.a.a");
|
|
aes_decrypt.a.overload("[B","[B").implementation = function(var_0,var_1) {
|
|
send("sg.vantagepoint.a.a.a([B[B)[B doFinal(enc) // AES/ECB/PKCS7Padding");
|
|
send("Key : " + getString(var_0));
|
|
send("Encrypted : " + getString(var_1));
|
|
var ret = this.a.overload("[B","[B").call(this,var_0,var_1);
|
|
send("Decrypted : " + ret);
|
|
|
|
var flag = "";
|
|
for (var i=0; i < ret.length; i++){
|
|
flag += String.fromCharCode(ret[i]);
|
|
}
|
|
send("Decrypted flag: " + flag);
|
|
return ret; //[B
|
|
};
|
|
```
|
|
### Hookowanie funkcji i wywoływanie ich z naszym wejściem
|
|
|
|
Zahacz funkcję, która przyjmuje ciąg znaków i wywołaj ją z innym ciągiem znaków (od [tutaj](https://11x256.github.io/Frida-hooking-android-part-2/)).
|
|
```javascript
|
|
var string_class = Java.use("java.lang.String"); // get a JS wrapper for java's String class
|
|
|
|
my_class.fun.overload("java.lang.String").implementation = function(x){ //hooking the new function
|
|
var my_string = string_class.$new("My TeSt String#####"); //creating a new String by using `new` operator
|
|
console.log("Original arg: " +x );
|
|
var ret = this.fun(my_string); // calling the original function with the new String, and putting its return value in ret variable
|
|
console.log("Return value: "+ret);
|
|
return ret;
|
|
};
|
|
```
|
|
### Pobieranie już utworzonego obiektu klasy
|
|
|
|
Jeśli chcesz wyodrębnić pewną cechę utworzonego obiektu, możesz to zrobić za pomocą tego sposobu.
|
|
|
|
W tym przykładzie zobaczysz, jak pobrać obiekt klasy my\_activity i jak wywołać funkcję .secret(), która wyświetli prywatną cechę obiektu:
|
|
```javascript
|
|
Java.choose("com.example.a11x256.frida_test.my_activity" , {
|
|
onMatch : function(instance){ //This function will be called for every instance found by frida
|
|
console.log("Found instance: "+instance);
|
|
console.log("Result of secret func: " + instance.secret());
|
|
},
|
|
onComplete:function(){}
|
|
});
|
|
```
|
