进程线程创建与退出监视（DBGVIEW打印）
曾经想着做个自己的主动防御项目，就是监控而已，实现RING3通信，各方参考学习，想着HOOK 来着
但是有一次知道了无HOOK的方式，感觉这挺方便呀 还是微软承认的函数，那我就实现一套监控的方案，考虑到逆向分析的话就准备后面
有事没事空闲了就去尽量实现HOOK的方式，希望一切顺利，少蓝屏几次。谢谢胡老师教程指导！
这里是代码和注意：实现的是监控进程线程创建退出，如果calc创建则阻止创建（W7 64位通过）
其中注意的是：
进程监视函数
PsSetCreateProcessNotifyRoutineEx（MSDN可查）。此函数的原型为：
| NTSTATUS PsSetCreateProcessNotifyRoutineEx( __in PCREATE_PROCESS_NOTIFY_ROUTINE_EX NotifyRoutine, __in BOOLEAN Remove ); |
接下来注意回调函数 NotifyRoutine 的原型：
| VOID CreateProcessNotifyEx( __inout PEPROCESS Process, //新进程 EPROCESS __in HANDLE ProcessId, //新进程 PID __in_opt PPS_CREATE_NOTIFY_INFO CreateInfo //新进程详细信息（仅在创建进程时有效） ); |
接下来看看 PS_CREATE_NOTIFY_INFO 结构体的定义：
| typedef struct _PS_CREATE_NOTIFY_INFO { SIZE_T Size; union { ULONG Flags; struct { ULONG FileOpenNameAvailable :1; ULONG Reserved :31; }; }; HANDLE ParentProcessId; CLIENT_ID CreatingThreadId; struct _FILE_OBJECT *FileObject; PCUNICODE_STRING ImageFileName; PCUNICODE_STRING CommandLine; NTSTATUS CreationStatus; } PS_CREATE_NOTIFY_INFO, *PPS_CREATE_NOTIFY_INFO; |
父进程 ID，父线ID
甚至直接包括程序的路径（不用通过 FileObject 来取，路径直接包含在了
ImageFileName 里）和命令行参数！
最紧要的是，如果要阻止进程创建，直接把
此结构体的 CreationStatus 成员改为 STATUS_UNSUCCESSFUL
线程监控函数：
NTKERNELAPI
NTSTATUS
PsSetCreateThreadNotifyRoutine(
_In_ PCREATE_THREAD_NOTIFY_ROUTINE NotifyRoutine
);（MSDN可查）
他的回调函数如下：
typedef
VOID
(*PCREATE_THREAD_NOTIFY_ROUTINE)(
_In_ HANDLE ProcessId,
_In_ HANDLE ThreadId,
_In_ BOOLEAN Create
);
这样很容易就看到进程 线程ID(句柄)了。而且第三位BOOLEAN型代表创建成功与否是一个 yes or no 的选择。
