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：

**\[cpp\]** view plain copy

print ?

1.  NTSTATUS DriverEntry(PDRIVER\_OBJECT pDriverObj, PUNICODE\_STRING pRegStr)  
2.  \{  
3.    
4.      pDriverObj->DriverUnload = MyUnload;  
5.    
6.      DbgPrint("DriverEntry...\\n");  
7.    
8.      //1.暴力枚举PID，枚举进程  
9.      for (ULONG i = 0; i < 65535; i += 4)  
10.     \{  
11.         SearchProcessPID(i);  
12.     \}  
13.     return STATUS\_SUCCESS;  
14. \}  
15. //暴力枚举PID，枚举进程  
16. NTSTATUS SearchProcessPID(ULONG pid)  
17. \{  
18.     NTSTATUS status = STATUS\_SUCCESS;  
19.     PEPROCESS process = NULL;  
20.     PUCHAR processName;  
21.     status = PsLookupProcessByProcessId((HANDLE)pid, &process);  
22.     processName = ExAllocatePool(NonPagedPool, sizeof(process));  
23.     if (NT\_SUCCESS(status))  
24.     \{  
25.         processName = PsGetProcessImageFileName(process);  
26.         DbgPrint("PID:%d,processName:%s\\n", pid, processName);  
27.     \}  
28.

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

**\[cpp\]** view plain copy

print ?

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.   
21.     return status;  
22. \}

    		}
    	} while (process != NULL);
    
    	return status;
