inline-hook和object双HOOK联合调用拒绝WIN打开服务
看标题其实很简单我也没有找到比较合适的标题，所以各位大牛们别嘲笑小弟就好，
原理很简单，其实就是找到个和对象有关的系统频繁调用的函数实现双HOOK就行啦，
我选折ObCreateObject函数下手，关于OBJECTHOOK的文章参考一下我的前篇科普篇
http://bbs.pediy.com/showthread.php?t=128161
我们先看下ObCreateObject函数原型先
NTSTATUS
ObCreateObject (
__in KPROCESSOR_MODE ProbeMode, // 决定是否要验证参数
__in POBJECT_TYPE ObjectType, // 对象类型指针
__in POBJECT_ATTRIBUTES ObjectAttributes, // 对象的属性, 最终会转化成ObAllocateObject需要的OBJECT_CREATE_INFORMATION结构
__in KPROCESSOR_MODE OwnershipMode, // 内核对象?用户对象?
__inout_opt PVOID ParseContext, // 这参数没用
__in ULONG ObjectBodySize, // 对象体大小
__in ULONG PagedPoolCharge, //
__in ULONG NonPagedPoolCharge, //
__out PVOID *Object // 接收对象体的指针
)
这里面有1个结构和一个对象对我们比较有用ObjectAttributes和ObjectType
ObjectType那那个科普帖已经介绍了，下面简单介绍一下这个结构
_OBJECT_ATTRIBUTES { ULONG Length;//结构长
HANDLE RootDirectory; //对象所在目录
PUNICODE_STRING ObjectName; //对象名
ULONG Attributes; //属性标志
PVOID SecurityDescriptor;
PVOID SecurityQualityOfService;
} OBJECT_ATTRIBUTES, *POBJECT_ATTRIBUTES;
这里面最重要还是ObjectType
直接上代码吧，太乱 因为是笔记

以上代码有危险性，因为比较极端，请大家在虚拟机上运行 我的测试环境是 windows_xp_professional_with_service_pack_3
1.有如下症状所有文件不能打开，右键选中打开的选项消失。如果需要分析工具请先运行再加载驱动
2.所有驱动不能加载，包括任务管理器 CMD 不能打开
3.无法关机和重启。
希望大家不要把代码运用到恶意程序上，其实也没多少技术含量，只是比较极端而已。如有BUG
欢迎大牛们指正，共同学习 共同进步嘛
