# InjectProc

Process injection is a very popular method to hide malicious behavior of code and are heavily used by malware authors.

There are several techniques, which are commonly used:

DLL injection, process replacement (a.k.a process hollowing), hook injection and APC injection.

Most of them use same Windows API functions: 

OpenProcess, VirtualAllocEx, WriteProcessMemory, for detailed information about those functions, use MSDN.

## DLL injection:

* Open target process.

* Allocate space.

* Write code into the remote process.

* Execute the remote code.

## Process replacement:

* Create target process and suspend it.

* Unmap from memory.

* Allocate space.

* Write headers and sections into the remote process.

* Resume remote thread.

## Hook injection:

* Find/Create process.

* Set hook

## Note: 

`InjectProc` uses [SetWindowsHookEx](https://msdn.microsoft.com/en-us/library/windows/desktop/ms644990(v=vs.85).aspx) function, you can try different ways to installing hooks, for example, [EasyHook](http://easyhook.github.io/tutorials/nativeremotehook.html)

## APC injection:

* Open process.

* Allocate space.

* Write code into remote threads.

* "Execute" threads using QueueUserAPC.

# Warning

Works on Windows 10 build 1703, 64bit.

I've not enough time to test other systems and make it portable if you have enough time please contribute.

I create this project for me to better understand how process injection works and 

I think it will be helpful for many beginner malware analysts too.
