Win7 x64动态开启DSE
本人研究这些东西没有人一起讨论 不支持研究的方向对不对 如果有误还请指出 我的联系方式:[email protected]
加载驱动 返回0xC0000428
IDA搜索立即数0xC0000428
发现有这么几个地方
看SeValidateImageHeader
很明显一个全局变量在影响这个判断 g_CiEnabled
看看那个地方在操作g_CiEnabled 发现是SepInitializeCodeIntegrity
这跟我们研究下面没有太大的关系 因为如果在这里path已经迟了 这个函数在系统启动的时候就运行了 当然如果要静态过DSE的话就在这里path
根据SeValidateImageHeader的反汇编可以看到 只需要对g_CiEnabled就行置0即可
在看看SeValidateImageData
这里也做了判断
这个函数其实没多大的作用qword_1402256A8其实就是CiValidateImageData的地址指针可在在windbg中查看 这个函数在ci.dll中
其它出现mov xxx,0xC0000428我在windbg双机调试中没有出现（加载驱动的时候没有断下）
还有一种方法不对g_CiEnabled处理 下面就调用了
result = g_CiCallbacks(a1, a2, a3, a4);
这个就是CiValidateImageHeader 我们去看看
这里还是直接找立即数吧 看看ci.dll是怎么 返回0xC0000428的
找了半天 CiValidateImageHeader 决定加载驱动的代码是
v20 = CipValidateFileHash(v19, v18, v17, v16);
g_CiOptions 默认是4 | 2 = 6 如果是6这就成立了 所以必须不为6 为0即可
另外一种解释
内核驱动初始化时调用SepInitializeCodeIntegrity
如果不是安全模式就走下面
注意下面这个v1 它决定了是否关闭DSE或测试模式
看CiInitialize_0 sub函数
看CiInitialize 注意第一个参数a1
去初始化ci.dll中的CiInitialize去看看 还是注意a1参数
来看看加载驱动是会调用哪些函数
去看看SeValidateImageHeader
去看看CiValidateImageHeader 这个应该不是这么执行的 我会在研究研究的
后面的再说
