[原创] 手脱Armadillo 5.0 (Standard + Debug-Blocker).学习笔记.
【文章标题】: 手脱Armadillo 5.0 (Standard + Debug-Blocker).学习笔记.
【文章作者】: wuhanqi
【作者邮箱】: wuhanqi@qq.com
【软件名称】: 一个unpackme
【下载地址】: 自己搜索下载
【加壳方式】: Armadillo 5.0 (Standard + Debug-Blocker)
【编写语言】: Delphi
【使用工具】: OD.ImportREC.LordPE.Arma Detach.PEID 0.94.FastScanner 2.1
【操作平台】: 盗版XP3
【作者声明】: 小菜一个.高手别笑话我哦~嘿嘿.
--------------------------------------------------------------------------------
【详细过程】
废话不多说.进入正题.脱壳目标为一个unpackme.
FastScan 2.1 查壳为 Microsoft Visual C++ 8
PEID 0.94 查壳为 Armadillo V5.0X -> Silicon Realms Toolworks * Sign.By.fly *
首先运行Armadillo Process Detach.将unpackme脱入Arma Detach中。
会显示内容如下:
DONE!
Child process ID: 000002C8
Entry point: 004A2DC2
Original bytes: E8E3
这时我们打开一个od.文件--附加.然后选中PID为2C8的进程.即为Armadillo的子进程.
我们载入后.F9.再F12.便断到如下代码处:
