r0遍历系统进程方法总结

方法1： ZwQuerySystemInformation

这个方法网上一搜一大堆，不举例了

方法2：暴力枚举PID枚举进程，代码：

1. NTSTATUS DriverEntry(PDRIVER_OBJECT pDriverObj, PUNICODE_STRING pRegStr)
2. {
3. pDriverObj->DriverUnload = MyUnload;
4. DbgPrint("DriverEntry...\n");
5. //1.暴力枚举PID，枚举进程
6. for (ULONG i = 0; i < 65535; i += 4)
7. {
8. SearchProcessPID(i);
9. }
10. return STATUS_SUCCESS;
11. }
12. //暴力枚举PID，枚举进程
13. NTSTATUS SearchProcessPID(ULONG pid)
14. {
15. NTSTATUS status = STATUS_SUCCESS;
16. PEPROCESS process = NULL;
17. PUCHAR processName;
18. status = PsLookupProcessByProcessId((HANDLE)pid, &process);
19. processName = ExAllocatePool(NonPagedPool, sizeof(process));
20. if (NT_SUCCESS(status))
21. {
22. processName = PsGetProcessImageFileName(process);
23. DbgPrint("PID:%d,processName:%s\n", pid, processName);
24. }

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriverObj, PUNICODE_STRING pRegStr)
{

	pDriverObj->DriverUnload = MyUnload;

	DbgPrint("DriverEntry...\n");

	//1.暴力枚举PID，枚举进程
	for (ULONG i = 0; i < 65535; i += 4)
	{
		SearchProcessPID(i);
	}
	return STATUS_SUCCESS;
}
//暴力枚举PID，枚举进程
NTSTATUS SearchProcessPID(ULONG pid)
{
	NTSTATUS status = STATUS_SUCCESS;
	PEPROCESS process = NULL;
	PUCHAR processName;
	status = PsLookupProcessByProcessId((HANDLE)pid, &process);
	processName = ExAllocatePool(NonPagedPool, sizeof(process));
	if (NT_SUCCESS(status))
	{
		processName = PsGetProcessImageFileName(process);
		DbgPrint("PID:%d,processName:%s\n", pid, processName);
	}
	

方法3和方法1原理相同，枚举eprocess结构体的ActiveProcessLinks链表实现，代码如下

1. //通过EPROCESS枚举进程
2. NTSTATUS SearchProcessEPROCESS()
3. {
4. PEPROCESS process=NULL,firstProcess=NULL;
5. NTSTATUS status = STATUS_SUCCESS;
6. PLIST_ENTRY plist;
7. process = firstProcess = PsGetCurrentProcess();
8. do
9. {
10. PUCHAR ProcessNmae = NULL;
11. ProcessNmae = PsGetProcessImageFileName(process);
12. DbgPrint("PID:%d,ProcessName:%s\n", (HANDLE)PsGetProcessId(process), ProcessNmae);
13. plist = (PLIST_ENTRY)((ULONG)process + ACTIVE_PROCESS_LINK);
14. process = (PEPROCESS)((ULONG)plist->Flink - ACTIVE_PROCESS_LINK);
15. if (process == firstProcess)
16. {
17. break;
18. }
19. } while (process != NULL);
20. return status;
21. }

//通过EPROCESS枚举进程
NTSTATUS SearchProcessEPROCESS()
{
	PEPROCESS process=NULL,firstProcess=NULL;
	NTSTATUS status = STATUS_SUCCESS;
	PLIST_ENTRY plist;
	process = firstProcess = PsGetCurrentProcess();
	do
	{
		PUCHAR ProcessNmae = NULL;
		ProcessNmae = PsGetProcessImageFileName(process);
		DbgPrint("PID:%d,ProcessName:%s\n", (HANDLE)PsGetProcessId(process), ProcessNmae);
		plist = (PLIST_ENTRY)((ULONG)process + ACTIVE_PROCESS_LINK);
		process = (PEPROCESS)((ULONG)plist->Flink - ACTIVE_PROCESS_LINK);
		if (process == firstProcess)
		{
			break;
		}
	} while (process != NULL);

	return status;
}
