## Installing Frida
|
||
|
||
**Steps to install Frida on a Jailbroken device:**
|
||
|
||
1. Open Cydia/Sileo app.
|
||
2. Navigate to Manage -> Sources -> Edit -> Add.
|
||
3. Enter "https://build.frida.re" as the URL.
|
||
4. Go to the newly added Frida source.
|
||
5. Install the Frida package.
|
||
|
||
If you are using **Corellium** you will need to download the Frida release from [https://github.com/frida/frida/releases](https://github.com/frida/frida/releases) (`frida-gadget-[yourversion]-ios-universal.dylib.gz`) and unpack and copy to the dylib location Frida asks for, e.g.: `/Users/[youruser]/.cache/frida/gadget-ios.dylib`
|
||
|
||
After installed, you can use in your PC the command **`frida-ls-devices`** and check that the device appears (your PC needs to be able to access it).\
|
||
Execute also **`frida-ps -Uia`** to check the running processes of the phone.
|
||
|
||
## Frida without Jailbroken device & without patching the app
|
||
|
||
Check this blog post about how to use Frida in non-jailbroken devices without patching the app: [https://mrbypass.medium.com/unlocking-potential-exploring-frida-objection-on-non-jailbroken-devices-without-application-ed0367a84f07](https://mrbypass.medium.com/unlocking-potential-exploring-frida-objection-on-non-jailbroken-devices-without-application-ed0367a84f07)
|
||
|
||
## Frida Client Installation
|
||
|
||
Install **frida tools**:
|
||
|
||
```bash
|
||
pip install frida-tools
|
||
pip install frida
|
||
```
|
||
|
||
With the Frida server installed and the device running and connected, **check** if the client is **working**:
|
||
|
||
```bash
|
||
frida-ls-devices # List devices
|
||
frida-ps -Uia # Get running processes
|
||
```
|
||
|
||
## Frida Trace
|
||
|
||
```bash
|
||
# Functions
|
||
## Trace all functions with the word "log" in their name
|
||
frida-trace -U <program> -i "*log*"
|
||
frida-trace -U <program> -i "*log*" | swift demangle # Demangle names
|
||
|
||
# Objective-C
|
||
## Trace all methods of all classes
|
||
frida-trace -U <program> -m "*[* *]"
|
||
|
||
## Trace all methods with the word "authentication" from classes that start with "NE"
|
||
frida-trace -U <program> -m "*[NE* *authentication*]"
|
||
|
||
# Plug-In
|
||
## To hook a plugin that is momentarely executed prepare Frida indicating the ID of the Plugin binary
|
||
frida-trace -U -W <if-plugin-bin> -m '*[* *]'
|
||
```
|
||
|
||
### Get all classes and methods
|
||
|
||
* Auto complete: Just execute `frida -U <program>`
|
||
|
||
<figure><img src="../../.gitbook/assets/image (1159).png" alt=""><figcaption></figcaption></figure>
|
||
|
||
* Get **all** available **classes** (filter by string)
|
||
|
||
{% code title="/tmp/script.js" %}
|
||
```javascript
|
||
// frida -U <program> -l /tmp/script.js
|
||
|
||
var filterClass = "filterstring";
|
||
|
||
if (ObjC.available) {
|
||
for (var className in ObjC.classes) {
|
||
if (ObjC.classes.hasOwnProperty(className)) {
|
||
if (!filterClass || className.includes(filterClass)) {
|
||
console.log(className);
|
||
}
|
||
}
|
||
}
|
||
} else {
|
||
console.log("Objective-C runtime is not available.");
|
||
}
|
||
```
|
||
{% endcode %}
|
||
|
||
* Get **all** **methods** of a **class** (filter by string)
|
||
|
||
{% code title="/tmp/script.js" %}
|
||
```javascript
|
||
// frida -U <program> -l /tmp/script.js
|
||
|
||
var specificClass = "YourClassName";
|
||
var filterMethod = "filtermethod";
|
||
|
||
if (ObjC.available) {
|
||
if (ObjC.classes.hasOwnProperty(specificClass)) {
|
||
var methods = ObjC.classes[specificClass].$ownMethods;
|
||
for (var i = 0; i < methods.length; i++) {
|
||
if (!filterMethod || methods[i].includes(filterClass)) {
|
||
console.log(specificClass + ': ' + methods[i]);
|
||
}
|
||
}
|
||
} else {
|
||
console.log("Class not found.");
|
||
}
|
||
} else {
|
||
console.log("Objective-C runtime is not available.");
|
||
}
|
||
```
|
||
{% endcode %}
|
||
|
||
* **Call a function**
|
||
|
||
```javascript
|
||
// Find the address of the function to call
|
||
const func_addr = Module.findExportByName("<Prog Name>", "<Func Name>");
|
||
// Declare the function to call
|
||
const func = new NativeFunction(
|
||
func_addr,
|
||
"void", ["pointer", "pointer", "pointer"], {
|
||
});
|
||
|
||
var arg0 = null;
|
||
|
||
// In this case to call this function we need to intercept a call to it to copy arg0
|
||
Interceptor.attach(wg_log_addr, {
|
||
onEnter: function(args) {
|
||
arg0 = new NativePointer(args[0]);
|
||
}
|
||
});
|
||
|
||
// Wait untill a call to the func occurs
|
||
while (! arg0) {
|
||
Thread.sleep(1);
|
||
console.log("waiting for ptr");
|
||
}
|
||
|
||
|
||
var arg1 = Memory.allocUtf8String('arg1');
|
||
var txt = Memory.allocUtf8String('Some text for arg2');
|
||
wg_log(arg0, arg1, txt);
|
||
|
||
console.log("loaded");
|
||
```
|
||
|
||
## Frida Fuzzing
|
||
|
||
### Frida Stalker
|
||
|
||
[From the docs](https://frida.re/docs/stalker/): Stalker is Frida’s code **tracing engine**. It allows threads to be **followed**, **capturing** every function, **every block**, even every instruction which is executed.
|
||
|
||
You have an example implementing Frida Stalker in [https://github.com/poxyran/misc/blob/master/frida-stalker-example.py](https://github.com/poxyran/misc/blob/master/frida-stalker-example.py)
|
||
|
||
This is another example to attach Frida Stalker every time a function is called:
|
||
|
||
```javascript
|
||
console.log("loading");
|
||
const wg_log_addr = Module.findExportByName("<Program>", "<function_name>");
|
||
const wg_log = new NativeFunction(
|
||
wg_log_addr,
|
||
"void", ["pointer", "pointer", "pointer"], {
|
||
});
|
||
|
||
Interceptor.attach(wg_log_addr, {
|
||
onEnter: function(args) {
|
||
console.log(`logging the following message: ${args[2].readCString()}`);
|
||
|
||
Stalker.follow({
|
||
events: {
|
||
// only collect coverage for newly encountered blocks
|
||
compile: true,
|
||
},
|
||
onReceive: function (events) {
|
||
const bbs = Stalker.parse(events, {
|
||
stringify: false,
|
||
annotate: false
|
||
});
|
||
console.log("Stalker trace of write_msg_to_log: \n" + bbs.flat().map(DebugSymbol.fromAddress).join('\n'));
|
||
}
|
||
});
|
||
},
|
||
onLeave: function(retval) {
|
||
Stalker.unfollow();
|
||
Stalker.flush(); // this is important to get all events
|
||
}
|
||
});
|
||
```
|
||
|
||
{% hint style="danger" %}
|
||
This is interesting from debugging purposes but for fuzzing, to be constantly **`.follow()`** and **`.unfollow()`** is very inefficient.
|
||
{% endhint %}

|
||
## [Fpicker](https://github.com/ttdennis/fpicker)
|
||
|
||
[**fpicker**](https://github.com/ttdennis/fpicker) is a **Frida-based fuzzing suite** that offers a variety of fuzzing modes for in-process fuzzing, such as an AFL++ mode or a passive tracing mode. It should run on all platforms that are supported by Frida.
|
||
|
||
* [**Install fpicker**](https://github.com/ttdennis/fpicker#requirements-and-installation) **& radamsa**
|
||
|
||
```bash
|
||
# Get fpicker
|
||
git clone https://github.com/ttdennis/fpicker
|
||
cd fpicker
|
||
|
||
# Get Frida core devkit and prepare fpicker
|
||
wget https://github.com/frida/frida/releases/download/16.1.4/frida-core-devkit-16.1.4-[yourOS]-[yourarchitecture].tar.xz
|
||
# e.g. https://github.com/frida/frida/releases/download/16.1.4/frida-core-devkit-16.1.4-macos-arm64.tar.xz
|
||
tar -xf ./*tar.xz
|
||
cp libfrida-core.a libfrida-core-[yourOS].a #libfrida-core-macos.a
|
||
|
||
# Install fpicker
|
||
make fpicker-[yourOS] # fpicker-macos
|
||
# This generates ./fpicker
|
||
|
||
# Install radamsa (fuzzer generator)
|
||
brew install radamsa
|
||
```
|
||
|
||
* **Prepare the FS:**
|
||
|
||
```bash
|
||
# From inside fpicker clone
|
||
mkdir -p examples/wg-log # Where the fuzzing script will be
|
||
mkdir -p examples/wg-log/out # For code coverage and crashes
|
||
mkdir -p examples/wg-log/in # For starting inputs
|
||
|
||
# Create at least 1 input for the fuzzer
|
||
echo Hello World > examples/wg-log/in/0
|
||
```
|
||
|
||
* **Fuzzer script** (`examples/wg-log/myfuzzer.js`):
|
||
|
||
{% code title="examples/wg-log/myfuzzer.js" %}
|
||
```javascript
|
||
// Import the fuzzer base class
|
||
import { Fuzzer } from "../../harness/fuzzer.js";
|
||
|
||
class WGLogFuzzer extends Fuzzer {
|
||
|
||
constructor() {
|
||
console.log("WGLogFuzzer constructor called")
|
||
|
||
// Get and declare the function we are going to fuzz
|
||
var wg_log_addr = Module.findExportByName("<Program name>", "<func name to fuzz>");
|
||
var wg_log_func = new NativeFunction(
|
||
wg_log_addr,
|
||
"void", ["pointer", "pointer", "pointer"], {
|
||
});
|
||
|
||
// Initialize the object
|
||
super("<Program nane>", wg_log_addr, wg_log_func);
|
||
this.wg_log_addr = wg_log_addr; // We cannot use "this" before calling "super"
|
||
|
||
console.log("WGLogFuzzer in the middle");
|
||
|
||
// Prepare the second argument to pass to the fuzz function
|
||
this.tag = Memory.allocUtf8String("arg2");
|
||
|
||
// Get the first argument we need to pass from a call to the functino we want to fuzz
|
||
var wg_log_global_ptr = null;
|
||
console.log(this.wg_log_addr);
|
||
Interceptor.attach(this.wg_log_addr, {
|
||
onEnter: function(args) {
|
||
console.log("Entering in the function to get the first argument");
|
||
wg_log_global_ptr = new NativePointer(args[0]);
|
||
}
|
||
});
|
||
|
||
while (! wg_log_global_ptr) {
|
||
Thread.sleep(1)
|
||
}
|
||
this.wg_log_global_ptr = wg_log_global_ptr;
|
||
console.log("WGLogFuzzer prepare ended")
|
||
}
|
||
|
||
|
||
// This function is called by the fuzzer with the first argument being a pointer into memory
|
||
// where the payload is stored and the second the length of the input.
|
||
fuzz(payload, len) {
|
||
// Get a pointer to payload being a valid C string (with a null byte at the end)
|
||
var payload_cstring = payload.readCString(len);
|
||
this.payload = Memory.allocUtf8String(payload_cstring);
|
||
|
||
// Debug and fuzz
|
||
this.debug_log(this.payload, len);
|
||
// Pass the 2 first arguments we know the function needs and finally the payload to fuzz
|
||
this.target_function(this.wg_log_global_ptr, this.tag, this.payload);
|
||
}
|
||
}
|
||
|
||
const f = new WGLogFuzzer();
|
||
rpc.exports.fuzzer = f;
|
||
```
|
||
{% endcode %}
|
||
|
||
* **Compile** the fuzzer:
|
||
|
||
```bash
|
||
# From inside fpicker clone
|
||
## Compile from "myfuzzer.js" to "harness.js"
|
||
frida-compile examples/wg-log/myfuzzer.js -o harness.js
|
||
```
|
||
|
||
* Call fuzzer **`fpicker`** using **`radamsa`**:
|
||
|
||
{% code overflow="wrap" %}
|
||
```bash
|
||
# Indicate fpicker to fuzz a program with the harness.js script and which folders to use
|
||
fpicker -v --fuzzer-mode active -e attach -p <Program to fuzz> -D usb -o examples/wg-log/out/ -i examples/wg-log/in/ -f harness.js --standalone-mutator cmd --mutator-command "radamsa"
|
||
# You can find code coverage and crashes in examples/wg-log/out/
|
||
```
|
||
{% endcode %}
|
||
|
||
{% hint style="danger" %}
|
||
In this case we **aren't restarting the app or restoring the state** after each payload. So, if Frida finds a **crash** the **next inputs** after that payload might also **crash the app** (because the app is in a unstable state) even if the **input shouldn't crash** the app.
|
||
|
||
Moreover, Frida will hook into exception signals of iOS, so when **Frida finds a crash**, probably an **iOS crash reports won't be generated**.
|
||
|
||
To prevent this, for example, we could restart the app after each Frida crash.
|
||
{% endhint %}
|
||
|
||
### Logs & Crashes
|
||
|
||
You can check the **macOS console** or the **`log`** cli to check macOS logs.\
|
||
You can check also the logs from iOS using **`idevicesyslog`**.\
|
||
Some logs will omit information adding **`<private>`**. To show all the info you need to install some profile from [https://developer.apple.com/bug-reporting/profiles-and-logs/](https://developer.apple.com/bug-reporting/profiles-and-logs/) to enable that private info.
|
||
|
||
If you don't know what to do:
|
||
|
||
```sh
|
||
vim /Library/Preferences/Logging/com.apple.system.logging.plist
|
||
<?xml version="1.0" encoding="UTF-8"?>
|
||
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
|
||
<plist version="1.0">
|
||
<dict>
|
||
<key>Enable-Private-Data</key>
|
||
<true/>
|
||
</dict>
|
||
</plist>
|
||
|
||
killall -9 logd
|
||
```
|
||
|
||
You can check the crashes in:
|
||
|
||
* **iOS**
|
||
* Settings → Privacy → Analytics & Improvements → Analytics Data
|
||
* `/private/var/mobile/Library/Logs/CrashReporter/`
|
||
* **macOS**:
|
||
* `/Library/Logs/DiagnosticReports/`
|
||
* `~/Library/Logs/DiagnosticReports`
|
||
|
||
{% hint style="warning" %}
|
||
iOS only stores 25 crashes of the same app, so you need to clean that or iOS will stop creating crashes.
