逆向调试入门-PE结构详解02/07

前一节我们详解了DOS头部,dos头部只有一个字段指向PE头部结构
el_fanew字段找到PE头部

PE头部结构

我们先来看下PE头部的三个结构体
前4个字节(04H)为PE标志位,一般为50450000。往后20字节(14H)为PE文件头

其中NumberOfSections为节数目(2字节长度)(0006h-0008h)
我们先来找个这个字段

OD上显示

OD调试器会进行分析

有个很重要的字段
AddressOfEntryPoint
指的是程序的真正入口。
我们可以通过目录来找到每个结构的RAV,并计算所需表的起始地址

PE的头部字段是比较重要的。
