在笔者上一篇文章 《驱动开发：内核特征码搜索函数封装》中为了定位特征的方便我们封装实现了一个可以传入数组实现的 SearchSpecialCode定位函数，该定位函数其实还不能算的上简单，本章 LyShark将对特征码定位进行简化，让定位变得更简单，并运用定位代码实现扫描内核PE的 .text代码段，并从代码段中得到某个特征所在内存位置。
老样子为了后续教程能够继续，先来定义一个 lyshark.h头文件，该头文件中包含了我们本篇文章所必须要使用到的结构体定义，这些定义的函数如果不懂请去看 LyShark以前的文章，这里就不罗嗦了。

我们继续，首先实现特征码字符串的解析与扫描实现此处 UtilLySharkSearchPattern函数就是 LyShark封装过的，这里依次介绍一下参数传递的含义。
- pattern 用于传入一段字符串特征值
(以\x开头) - len 代表输入特征码长度
(除去\x后的长度) - base 代表扫描内存的基地址
- size 代表需要向下扫描的长度
- ppFound 代表扫描到首地址以后返回的内存地址
这段代码该如何使用，如下我们以定位 IoInitializeTimer为例，演示 UtilLySharkSearchPattern如何定位特征的，如下代码 pattern变量中就是我们需要定位的特征值， pattern_size则是需要定位的特征码长度，在 address地址位置向下扫描 128字节，找到则返回到 find_address变量内。

运行驱动程序完成特征定位，并对比定位效果。
如上述所示定位函数我们已经封装好了，相信你也能感受到这种方式要比使用数组更方便，为了能定位到内核PE结构我们需要使用 RtlImageNtHeader来解析，这个内核函数专门用来得到内核程序的PE头部结构的，在下方案例中首先我们使用封装过的 LySharkToolsUtilKernelBase函数拿到内核基址，如果你不懂函数实现细节请阅读 《驱动开发：内核取ntoskrnl模块基地址》这篇文章，拿到基址以后可以直接使用 RtlImageNtHeader对其PE头部进行解析，如下所示。

}
VOID UnDriver(PDRIVER_OBJECT driver)
{

}
NTSTATUS DriverEntry(IN PDRIVER_OBJECT Driver, PUNICODE_STRING RegistryPath)
{
DbgPrint(("hello lyshark.com \n"));
// 获取内核第一个模块的基地址
PVOID base = LySharkToolsUtilKernelBase(0);
if (!base)
return STATUS_NOT_FOUND;
// 得到NT头部PE32+结构
// lyshark.com
PIMAGE_NT_HEADERS64 pHdr = RtlImageNtHeader(base);
if (!pHdr)
return STATUS_INVALID_IMAGE_FORMAT;
// 首先寻找代码段
PIMAGE_SECTION_HEADER pFirstSection = (PIMAGE_SECTION_HEADER)(pHdr + 1);
for (PIMAGE_SECTION_HEADER pSection = pFirstSection; pSection < pFirstSection + pHdr->FileHeader.NumberOfSections; pSection++)
{
ANSI_STRING LySharkSection, LySharkName;
RtlInitAnsiString(&LySharkSection, ".text");
RtlInitAnsiString(&LySharkName, (PCCHAR)pSection->Name);
DbgPrint("[LyShark.PE] 名字: %Z | 地址: %p | 长度: %d \n", LySharkName, (PUCHAR)base + pSection->VirtualAddress, pSection->Misc.VirtualSize);

运行这段驱动程序，你会得到 当前内核的 所有PE节信息，枚举效果如下所示。
既然能够得到PE头部数据了，那么我们只需要扫描这段空间并得到匹配到的数据即可，其实很容易实现，如下代码所示。

DbgPrint("[LyShark] 输出首地址: %p", m_MiProcessLoaderEntry);
}
}
Driver->DriverUnload = UnDriver;
return STATUS_SUCCESS;
}
代码中首先判断系统主版本 windows 10 18363如果是则执行匹配，只匹配 .text也就是代码段中的数据，当遇到 0xcc时则取消继续，否则继续执行枚举，程序输出效果如下所示。
在WinDBG中输入命令 !dh 0xfffff8007f600000解析出内核PE头数据，可以看到如下所示，对比无误。
