Tutorial Objective-C And Hacks

WHAT IS HACKS and what is Objective-C ?

There are many programming languages, some of which are limited in usage, while others are widely used.

To understand how to create code to hack an application or game, you must grasp the nature of the language you desire and the platform it targets, such as iPhone, PC, or even Android.

Let's assume you want to develop a script for the iPhone. The iPhone understands several languages, including Objective-C and Swift, among others. However, most hacking programs are written in Objective-C. So, let's explain the nature of this great language and how you can use it to develop your programs, and even hack some applications, for example, by injecting using MS hook or modifying offsets and hex values.

To create a script for hacking programs and games, you first need to have the Theos program for software development and tweaks or maybe your jailbroken phone . Secondly, you must possess the offset for the application you want to hack, for example, the offset for the game Clash of Clans with the value x548461. This offset contains a value called hex. Let's assume the offset's name is "gold" and its value is an integer or numeric value. This offset can be hacked, and the gold can be increased by modifying the hex, for example, to 02008052C0035FD6. This 16-digit number is called the HEX and is commonly used for hacking and changing the values of functions within applications.

How can I determine the offset value? This will be explained later.

And now, let's assume that you have the name of the function you want to hack, for example, PUBLIC GET_GOLD (GET) INT. This function returns an integer value, meaning a number, and gives the player a gold value. You can inject this function using MSHOOK in Theos program. Let's create a new project in Theos and choose TWEAK, then follow these steps.

1-OPEN Tweak.xm or Tweak.x

2-put this code in main fuc

3-you should change PlayerInfo and IsVip

4-You should put the library to useing MS HOOK put this in top of tweak file #import <substrate.h>

%hook PlayerInfo
-(BOOL)IsVip {
// inject your code here
return YES; // fuc will be true
}

%end

or another one like that

%hook PlayerInfo
-(BOOL)IsVip {

return YES;
}
%end

or If you need to hack int we used

%hook PlayerInfo
-(int)get_gold {
// Inject your code here
int get_gold = 1; // Set the get_gold value to 1 as an example
return get_gold; // The function will return, for example, 1
}
%end

In top example this inject will make the player always VIP

And now, that's all for this moment. There are many upcoming tutorials where we will delve deeper into offsets, how to find them, and create practical examples through videos. Additionally, we'll explore some applications like IDA Pro and even DNSpy, among others, that are useful for this purpose.

return get_gold; // The function will return, for example, 1
}
%end

Could you please advice me - I understood correctly that PlayerInfo is a class and it can be changed for example to PropMng ? And if we want to make a tweak with offset for example 25D0B6C in which is located

public int GetPrice(PropID id)
{
	return 0;
}

do we have to specify this offset somewhere and have it return 00F0271EC0035FD6 in hex ? or do we just write in total like this and convert hex to decimal value

%hook PropMng
-(int)GetPrice{
	int GetPrice = 144256280972976086;
	return GetPrice;
}
%end

YOU CAN use your script sec one that one here

%hook PropMng
-(int)GetPrice{
int GetPrice = 144256280972976086;
return GetPrice;
}
%end

you can skip offset for hooking this class just make sure class name and method is the same in app that you want to hack
