2.2.2 IDA Pro
快捷键
;
:为当前指令添加全文交叉引用的注释n
:定义或修改名称,通常用来标注函数名g
:跳转到任意地址Esc
:返回到跳转前的位置D
:分别按字节、字、双字显示数据A
:按 ASCII 显示数据

常用脚本
内存 dump 脚本
调试程序时偶尔会需要 dump 内存,但 IDA Pro 没有直接提供此功能,可以通过脚本来实现。
import idaapi
data = idaapi.dbg_read_memory(start_address, data_length)
fp = open('path/to/dump', 'wb')
fp.write(data)
fp.close()
技巧
堆栈不平衡
某些函数在使用 f5 进行反编译时,会提示错误 sp-analysis failed
,导致无法正确反编译。原因可能是在代码执行中的 pop、push 操作不匹配,导致解析的时候 esp 发生错误。
解决办法步骤如下:
- 用 Option->General->Disassembly,将选项 Stack pointer 打钩
- 仔细观察每条 call sub_xxxxxx 前后的堆栈指针是否平衡
- 有时还要看被调用的 sub_xxxxxx 内部的堆栈情况,主要是看入栈的参数与 ret xx 是否匹配
- 注意观察 jmp 指令前后的堆栈是否有变化
- 有时用 Edit->Functions->Edit function...,然后点击 OK 刷一下函数定义
