This library is meant to be created to test rust's capability for game hacking. u know it's kinda far from normal programming, right? However, cuz I was too lazy and beginner this library is relatively high level, meaning it doesnt use either Nt or Zw API, and it's only capable of things that a user-mode application does. Dont get it something fancy, rather consider this as my training of rust, can't guarantee the quality of the code. Oh, and never ever mention about the bizzar project structure, even if it looks bloody cringy. My bad.
But before actually test the example, I'll show you some preparation steps you're supposed to know.
Firstly, include toy-arms in your dependencies' table in Cargo.toml.
As of now toy-arms has 2 features which are internal and external.
internal feature flag is on by default so you have to specify external when you wanna use it.
for internal use:
[dependencies]
toy-arms = {git = "version = "https://github.com/vxcall/toy-arms"}
# This annotation below is to tell the compiler to compile this into dll. MUST.
[lib]
crate-type = ["cdylib"]for external use:
[dependencies]
toy-arms = {git = "https://github.com/vxcall/toy-arms", features = ["external"]}Secondly, sicne most of those tests are targeting the game "csgo.exe(x86)", you may have to build the code in x86 architecture depending on the example.
You can either specify in .cargo/config.toml as following:
[build]
target = "i686-pc-windows-msvc"Or put --target i686-pc-windows-msvc flag everytime when you build the code.
If you don't have toolchain for 32bit msvc, do following
rustup target add i686-pc-windows-msvc In this section I'll showcase you various examples for different situations with internal and external features. Find one fits your purpose.
Be informed that all these examples are happened to target CSGO:counter strike global offencive , so be sure to get it and test with it.
Welcome to the examples of internal hack. A dll file will be generated by build these examples, inject it with whatever dll injector you possess.
With this crate, making the injectable dll which is the smallest possible is simple as this:
cargo b --example in_simplest_dll --target i686-pc-windows-msvc
/*
This is the demonstration of how to make the simplest hack with toy-arms.
*/
// A neat macro which defines entry point instead of you.
// Also, you dont have to alloc/free console by yourself, console will show up when u compile into debug build.
internal::create_entrypoint!(hack_main_thread);
// Main thread
fn hack_main_thread() {
// YOUR STUNNING CODE'S SUPPOSED TO BE HERE;
for i in 0..30000 {
println!("using toy-arms {}", i);
}
}This is the code that overwrites the value at DW_FORCE_ATTACK to 0x5 every loop in csgo.exe.
Note that you have to check if the address of DW_FORCE_ATTACK is up-to-date.
cargo b --example in_auto_shoot --target i686-pc-windows-msvc
/*
This is the demonstration of how to use internal analysis feature in toy-arms.
This code gets module handle and function address of the func called MessageBoxA as an example.
Then read the value called dwForceAttack and overwrite it to make player shoot.
The offset DW_FORCE_ATTACK works as of the day i wrote this but it might not be up to date in your case.

let mut once = false;
// Gets module handle

println!("module handle = {:?}", module_handle as usize);
let shoot_flag = cast!(mut module_handle as usize + DW_FORCE_ATTACK, u8);
loop {

println!("Press INSERT to exit...");
once = !once;

if detect_keypress(VirtualKeyCode::VK_INSERT) {
break;
}
// just flexing this neat function xd.
if detect_keydown!(VirtualKeyCode::VK_HOME) {
println!("HOME is both pressed");
}
}
}While this code below will retrieve health value of LocalPlayer object in csgo.exe.
Note that you have to update the offset of DW_LOCAL_PLAYER.
cargo b --example in_get_localplayer_health --target i686-pc-windows-msvc
/*
This example is the demonstration of getting player health with toy-arms internal memory analysis feature.

also, the offset of DW_LOCAL_PLAYER works as of the day i wrote this but it might not be up to date in your case.

}This is the pattern scanning example where the pattern is for dwForceAttack in csgo.

}On the other hand, following code is how tamper with memory externally is like.
This is the code that overwrites the value at DW_FORCE_ATTACK to 0x5 every loop in csgo.exe.
Note that you have to check if the address of DW_FORCE_ATTACK is up-to-date.

}Retrieving local player health demo is present as below. Quick tip: You don't wanna use usize as the pointer type cuz external program itself is going to be 64bit, therefore the buffer size will be 8bytes whereas the actual pointer is 4bytes. Use u32 or DWORD instead.

}This is the pattern scanning example where the pattern is for dwForceAttack in csgo.

}Yes you have! Take a look at examples directory, you'll see more examples!
However, you may need to update offsets which some examples contain with your own hands.
Refer to hazedumper as always for latest offsets of CSGO.
To build examples in x86 arch:
cargo build --example EXAMPLE_NAME --target i686-pc-windows-msvcfn read<T>(
process_handle: &HANDLE,
base_address: usize,
size: usize,
buffer: *mut T,
)make sure to pass buffer like following:
let mut buffer: u32 = 0; // Declare with mut keyword
read::<u32>(
&handle,
base_address,
size_of::<u32>(),
&mut buffer as *mut u32, // Must be the form of &mut buffer as *mut T
// These are equivalent to &buffer in C++.
);in the example, both of them are used conditionally. They are present for different use.
cast!() is the basic dereference and u can always use this of course.
read() is the member method of Module struct. It allows u to just pass the offset of what u want from module base, and it adds them for you. cast!() is used under the hood.
