This repository documents and demonstrates different Windows process injection methods. Each technique leverages low-level Windows APIs to run arbitrary shellcode inside a target process.

Method: Uses NtCreateSection, NtMapViewOfSection, and RtlCreateUserThread.
Reference: phasetw0 – Section Code Injection

1. Launch a host process (e.g., notepad.exe) that will execute the shellcode.
2. Create a memory section with RWX permissions via NtCreateSection.
3. Map the section into the local process with RW permissions using NtMapViewOfSection.
4. Map the same section into the remote target process with RX permissions.
5. Write the shellcode into the local mapped view → this change is reflected in the remote mapped section.
6. Start execution by creating a remote thread in the target process via RtlCreateUserThread, pointing it to the injected shellcode.

Method: Uses Asynchronous Procedure Calls (APCs) to run code inside an alertable thread of a target process.
Reference: Modexp – APC Injection
Reference: ired.team – APC Queue Injection

1. Identify the PID of a target process (explorer.exe).
2. Allocate memory inside the target process with RWX permissions.
3. Write the shellcode into that allocated memory.
4. Enumerate threads of the target process, then find an alertable thread (by checking its context/state).
5. Queue an APC pointing to the injected shellcode. When the thread enters an alertable state, the shellcode executes.
