## Kusakinisha Frida

**Hatua za kusakinisha Frida kwenye kifaa kilichofanyiwa Jailbreak:**

1. Fungua programu ya Cydia/Sileo.
2. Nenda kwa Usimamizi -> Vyanzo -> Hariri -> Ongeza.
3. Ingiza "https://build.frida.re" kama URL.
4. Nenda kwenye chanzo cha Frida kilichoongezwa hivi karibuni.
5. Sakinisha pakiti ya Frida.

Ikiwa unatumia **Corellium** utahitaji kupakua kutolewa kwa Frida kutoka [https://github.com/frida/frida/releases](https://github.com/frida/frida/releases) (`frida-gadget-[yourversion]-ios-universal.dylib.gz`) na kufungua na kunakili kwenye eneo la dylib ambalo Frida inahitaji, k.m.: `/Users/[youruser]/.cache/frida/gadget-ios.dylib`

Baada ya kusakinishwa, unaweza kutumia amri **`frida-ls-devices`** kwenye PC yako na kuhakikisha kuwa kifaa kinaonekana (PC yako inahitaji kuweza kufikia).\
Tumia pia **`frida-ps -Uia`** kuchunguza michakato inayoendeshwa kwenye simu.

## Frida bila kifaa kilichofanyiwa Jailbreak & bila kubadilisha programu

Angalia chapisho hili la blogu kuhusu jinsi ya kutumia Frida kwenye vifaa visivyofanyiwa Jailbreak bila kubadilisha programu: [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)

## Usakinishaji wa Mteja wa Frida

Sakinisha **zana za frida**:
```bash
pip install frida-tools
pip install frida
```
Baada ya kusakinisha seva ya Frida na kifaa kikiwa kinaendeshwa na kimeunganishwa, **angalia** kama mteja anafanya kazi:
```bash
frida-ls-devices  # List devices
frida-ps -Uia     # Get running processes
```
## Kufuatilia kwa Frida
```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 '*[* *]'
```
### Pata madarasa na njia zote

* Kukamilisha moja kwa moja: Tekeleza tu `frida -U <program>`

<figure><img src="../../.gitbook/assets/image (1159).png" alt=""><figcaption></figcaption></figure>

* Pata **madarasa yote** yanayopatikana (pambanua kwa herufi)
```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 %}

* Pata **njia zote** za **darasa** (chuja kwa herufi)
```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 %}

* **Piga simu kwa kazi**
```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

[Kutoka kwa nyaraka](https://frida.re/docs/stalker/): Stalker ni injini ya **kufuatilia** ya Frida. Inaruhusu nyuzi kufuatiliwa, **kukamata** kila kazi, **kila kibodi**, hata kila maagizo yanayotekelezwa.

Unayo mfano unaoendeleza Frida Stalker katika [https://github.com/poxyran/misc/blob/master/frida-stalker-example.py](https://github.com/poxyran/misc/blob/master/frida-stalker-example.py)

Huu ni mfano mwingine wa kuambatisha Frida Stalker kila wakati kazi inaitwa:
```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" %}
Hii ni ya kuvutia kwa madhumuni ya kutatua matatizo lakini kwa fuzzing, kuwa kila wakati **`.follow()`** na **`.unfollow()`** ni ya ufanisi sana.
{% endhint %}

## [Fpicker](https://github.com/ttdennis/fpicker)

[**fpicker**](https://github.com/ttdennis/fpicker) ni **zana ya kufanya fuzzing kwa kutumia Frida** ambayo inatoa aina mbalimbali za modes za fuzzing kwa fuzzing ndani ya mchakato, kama vile mode ya AFL++ au mode ya ufuatiliaji wa kupita. Inapaswa kuendesha kwenye majukwaa yote yanayoungwa mkono na Frida.

* [**Sakinisha 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
```
* **Jitayarisha 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
```
* **Skripti la Fuzzer** (`mfano/wg-log/myfuzzer.js`):

{% code title="mfano/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 %}

* **Kusanya** fuzzer:
```bash
# From inside fpicker clone
## Compile from "myfuzzer.js" to "harness.js"
frida-compile examples/wg-log/myfuzzer.js -o harness.js
```
* Piga fuzzer **`fpicker`** ukitumia **`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" %}
Katika kesi hii **hatuwezi kuanza upya programu au kurejesha hali** baada ya kila mzigo. Kwa hivyo, ikiwa Frida inagundua **kosa** baada ya mzigo huo, **matokeo ya kuingiza baada ya mzigo huo** yanaweza pia **kusababisha programu kugonga** (kwa sababu programu iko katika hali isiyo thabiti) hata kama **kuingiza haipaswi kusababisha** programu kugonga.

Zaidi ya hayo, Frida itaunganisha ishara za kipekee za iOS, kwa hivyo wakati **Frida inapogundua kosa**, labda **ripoti za kugonga za iOS hazitazalishwa**.

Ili kuzuia hili, kwa mfano, tunaweza kuanza upya programu baada ya kila kugonga cha Frida.
{% endhint %}

### Kumbukumbu & Kugonga

Unaweza kuangalia **konsoli ya macOS** au **cli ya `log`** kuangalia kumbukumbu za macOS.\
Unaweza pia kuangalia kumbukumbu kutoka iOS kwa kutumia **`idevicesyslog`**.\
Baadhi ya kumbukumbu zitakosa taarifa kwa kuongeza **`<binafsi>`**. Ili kuonyesha taarifa zote unahitaji kusakinisha wasifu fulani kutoka [https://developer.apple.com/bug-reporting/profiles-and-logs/](https://developer.apple.com/bug-reporting/profiles-and-logs/) kuwezesha taarifa hizo za binafsi.

Ikiwa hujui cha kufanya:
```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
```
Unaweza kuangalia ajali katika:

* **iOS**
* Mipangilio → Faragha → Takwimu za Uchambuzi na Maboresho → Takwimu za Uchambuzi
* `/private/var/mobile/Library/Logs/CrashReporter/`
* **macOS**:
* `/Library/Logs/DiagnosticReports/`
* `~/Library/Logs/DiagnosticReports`

{% hint style="warning" %}
iOS inahifadhi ajali 25 za programu ile ile tu, hivyo unahitaji kusafisha hiyo au iOS itasita kuunda ajali.
{% endhint %}
