What's toy-arms?

This is a toolkit for those who are fed up with coding game hack with C++ but still wanna make it in an elegant way. Since this library wraps many Windows API which frequently used, you can build hack without having to struggle with it. By using this, many part of your stress while coding low level fashion won't come in.

But be informed that since I'm neither a pro rust coder nor a pro game hacker, this library still might contain some buggy code which causes unintentional behavior. I'd be pleased if you help me improve toy-arms by spotting them and make PR or issue.

📌 Table of contents

💕 support me

Donating me through GitHub sponsors would be the best way to support me and this project. You can also support me by starring this project, or any kind of PR that either refactoring this project, or adding new feature would pump me up!

🔥 Get started

But before actually test the example, I'll show you some preparation steps you're supposed to know.

step1

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 = "0.9.4"

# This annotation below is to tell the compiler to compile this into dll. MUST.
[lib]
crate-type = ["cdylib"]

for external use:

[dependencies]
toy-arms = {version = "0.9.4", features = ["external"]}

step2

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.

📜 Practical Examples

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.

internal

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.

simplest dll (internal)

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

// 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.
toy_arms::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);
  }
}

auto shoot (internal)

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

use toy_arms::VirtualKeyCode;
use toy_arms::external::Process;
use toy_arms::external::{ read, write };

fn main() {
  // This const has to be up to date.
  const DW_CLIENT_STATE: usize = 0x58CFC4;
  const DW_CLIENT_STATE_STATE: usize = 0x108;
  const DW_FORCE_ATTACK: usize = 0x31FE33C;
  // Getting process information
  let process = Process::from_process_name("csgo.exe");
  println!(
    "process id = {}, \nprocess handle = {:?}",
    process.process_id, process.process_handle
  );

  // You can get module information by using get_module_info
  let module_info = process.get_module_info("client.dll").unwrap();
  println!("{}", module_info.module_name);

  // read fetches the value at where the address is pointing.
  // U have to specify the type of the value with turbofish
  println!(
    "{:x}",
    read::<i32>(process.process_handle, read::<u32>(process.process_handle, process.get_module_base("engine.dll").unwrap() + DW_CLIENT_STATE).unwrap() as usize + DW_CLIENT_STATE_STATE).unwrap()
  );

  loop {
    // write helps you tamper with the value.
    write::<u32>(
      process.process_handle,
      process.get_module_base("client.dll").unwrap() + DW_FORCE_ATTACK as usize,
      &mut 0x5,
    )
            .unwrap();

    // Exit this loop by pressing INSERT
    if toy_arms::detect_keypress(VirtualKeyCode::VK_INSERT) {
      break;
    }
  }
}

get localplayer health (internal)

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_localplayer_health --target i686-pc-windows-msvc

use toy_arms::GameObject;
use toy_arms::{cast, create_entrypoint, VirtualKeyCode};
use toy_arms::internal::Module;
use toy_arms_derive::GameObject;

create_entrypoint!(hack_main_thread);

// This macro provides from_raw() func that ensures the base address is not null.
#[derive(GameObject)]
struct LocalPlayer {
  pointer: *const usize, // Denote the base address of LocalPlayer to use it later in get_health() function.
}

impl LocalPlayer {
  unsafe fn get_health(&self) -> u16 {
    *cast!(self.pointer as usize + 0x100, u16)
  }
}

// This offset has to be up to date.
const DW_LOCAL_PLAYER: i32 = 0xDB25DC;

fn hack_main_thread() {
  let module = Module::from_module_name("client.dll").unwrap();
  unsafe {
    //let dw_local_player = memory.read_mut::<LocalPlayer>(0xDA244C);
    loop {
      if let Some(i) = LocalPlayer::from_raw(module.read(DW_LOCAL_PLAYER)) {
        println!("health = {:?}", (*i).get_health());
      };
      if toy_arms::detect_keypress(VirtualKeyCode::VK_INSERT) {
        break;
      }
    }
  }
}

pattern scanning (internal)

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

cargo b --example in_pattern_scanning --target i686-pc-windows-msvc

use toy_arms::{
  detect_keypress,
  internal::{
    Module
  },
  VirtualKeyCode
};
toy_arms::create_entrypoint!(hack_main_thread);

const DW_FORCE_ATTACK_PATTERN: &str = "89 0D ? ? ? ? 8B 0D ? ? ? ? 8B F2 8B C1 83 CE 04";

fn hack_main_thread() {
  let mut once = false;

  let client = Module::from_module_name("client.dll").unwrap();

  match client.find_pattern(DW_FORCE_ATTACK_PATTERN) {
    Some(i) => println!("address: 0x{:x}", i),
    None => println!("Pattern not found"),
  }

  match client.pattern_scan(
    DW_FORCE_ATTACK_PATTERN,
    2,
    0,
  ) {
    Some(i) => println!("address: 0x{:x}", i),
    None => println!("Offset not found"),
  }

  loop {
    if !once {
      println!("Press INSERT to exit...");
      once = !once;
    }
    // To exit this hack loop when you input INSEERT KEY
    if detect_keypress(VirtualKeyCode::VK_INSERT) {
      break;
    }
  }
}

external

On the other hand, following code is how tamper with memory externally is like.

auto shoot (external)

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 r --example ex_auto_shoot --features external --no-default-features

use toy_arms::VirtualKeyCode;
use toy_arms::external::Process;
use toy_arms::external::{ read, write };

fn main() {
  // This const has to be up to date.
  const DW_CLIENT_STATE: usize = 0x58CFC4;
  const DW_CLIENT_STATE_STATE: usize = 0x108;
  const DW_FORCE_ATTACK: usize = 0x31FE33C;
  // Getting process information
  let process = Process::from_process_name("csgo.exe");
  println!(
    "process id = {}, \nprocess handle = {:?}",
    process.process_id, process.process_handle
  );

  // You can get module information by using get_module_info
  let module_info = process.get_module_info("client.dll").unwrap();
  println!("{}", module_info.module_name);

  // read fetches the value at where the address is pointing.
  // U have to specify the type of the value with turbofish
  println!(
    "{:x}",
    read::<i32>(process.process_handle, read::<u32>(process.process_handle, process.get_module_base("engine.dll").unwrap() + DW_CLIENT_STATE).unwrap() as usize + DW_CLIENT_STATE_STATE).unwrap()
  );

  loop {
    // write helps you tamper with the value.
    write::<u32>(
      process.process_handle,
      process.get_module_base("client.dll").unwrap() + DW_FORCE_ATTACK as usize,
      &mut 0x5,
    )
            .unwrap();

    // Exit this loop by pressing INSERT
    if toy_arms::detect_keypress(VirtualKeyCode::VK_INSERT) {
      break;
    }
  }
}

get localplayer health (external)

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.

cargo r --example ex_get_localplayer_health --features external --no-default-features

use toy_arms::external::{Module, Process, read};
use toy_arms::external::error::TAExternalError::ReadMemoryFailed;

const DW_LOCAL_PLAYER: u32 = 0xDB35DC;

fn main() {
  let csgo: Process;
  match Process::from_process_name("csgo.exe") {
    Ok(p) => csgo = p,
    Err(e) => {
      println!("{}", e);
      return;
    },
  }
  let client: Module;
  match csgo.get_module_info("client.dll") {
    Ok(m) => client = m,
    Err(e) => {
      println!("{}", e);
      return;
    },
  }

  println!("module_base: {:x}", client.module_base_address);
  println!("localplayer pointer: 0x{:x}", client.module_base_address + DW_LOCAL_PLAYER as usize);
  let localplayer = read::<u32>(csgo.process_handle, client.module_base_address + DW_LOCAL_PLAYER as usize);

  match localplayer {
    Ok(l) => {
      println!("localplayer address: 0x{:x}", l);
      // 0x100 is the offset of the health in player entity class.
      let health = read::<u16>(csgo.process_handle, l as usize + 0x100);
      match health {
        // This is what we wanted.
        Ok(h) => println!("localplayer's health: {}", h),
        Err(ReadMemoryFailed(e)) => println!("{}", e),
        Err(_) => println!("some error"),
      }
    },
    Err(e) => println!("error: {}", e),
  }
}

pattern scanning (external)

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

cargo r --example ex_pattern_scanning --features external --no-default-features

use toy_arms::{ VirtualKeyCode };
use toy_arms::external::Process;

const DW_FORCE_ATTACK_PATTERN: &str = "89 0D ? ? ? ? 8B 0D ? ? ? ? 8B F2 8B C1 83 CE 04";

fn main() {
  let mut once = false;

  // Getting process information
  let process = Process::from_process_name("csgo.exe");
  // You can get module information by using get_client
  let client = process.get_module_info("client.dll").unwrap();


  let address = client.find_pattern(DW_FORCE_ATTACK_PATTERN);
  match address {
    Some(i) => println!("found pattern at 0x{:x}", i),
    None => println!("NOTHING FOUND"),
  }

  let offset = client.pattern_scan(
    DW_FORCE_ATTACK_PATTERN,
    2,
    0,
  );
  match offset {
    Some(i) => println!("found offset at 0x{:x}", i),
    None => println!("NOTHING FOUND"),
  }

  loop {
    if !once {
      println!("Press INSERT to exit...");
      once = !once;
    }
    // Exit this loop by pressing INSERT
    if toy_arms::detect_keydown!(VirtualKeyCode::VK_INSERT) {
      break;
    }
  }
}

🗃️ Other examples?

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.
