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：

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriverObj, PUNICODE_STRING pRegStr)
{

    pDriverObj->DriverUnload = MyUnload;

    DbgPrint("DriverEntry...
");

    //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
", pid, processName);
    }

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriverObj, PUNICODE_STRING pRegStr)
{

	pDriverObj->DriverUnload = MyUnload;

	DbgPrint("DriverEntry...
");

	//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
", 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

//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
", (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;
}

//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
", (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;
}
