应用olldbg脱telock加壳之菜鸟篇

应用平台： Win95/98/NT/2000/XP  
破解工具：ollydbg 1.09汉化版、peid8cn、Hex Workshop 4.0、peditor、Lordpe工作平台WINXP（98死得惨）  
破解方法：学习如何脱壳  

脱壳过程：  
一、查壳找入口点，用peid8cn打开主程序，结果是telock0.98，入口点:5a172c（关键入口点用PEID8CN右下下拉菜单中的OEP查找搞定）  
二、用OLLYDBG载入主程序，第一对话框点确定，第二对话框点否，来到这儿

按SHIFT+F9运行到此处，查看ESI的值为001AA000  
然后在OLLYDBG左下角下命令D 005AA000(001AA000+400000)然后向下查找后面全部为00的地方来到5AD0F0  
用系统自带计算器计算5AD0F0-5AA000=30F0，为什么到这呢，而不是其它地方，向下太多会出错，向上也会出错，不能太多，也不能太少哦  
起动LordPe先主程序进程。点右键选部份脱壳，填上005AA000-------000030F0脱出输入表30F0.DMP备用，退出LORDPE，切换到OLLYDBG，F2取消断点，按SHIFT+F9继续到这

在左下角命令框下BP 5A172C(入口点哦)按SHIFT+F9运行到入口处，再次起动LORDPE选主程序点右键选完全脱壳脱出文件UNPACKED.EXE，退出OLLYDBG，  
三、置入输入表  
　　 起动HEX　WORKSHOP程序分别打开刚脱出的两个文件，在30F0文件按CRTL＋A　COPY，然后选打开的UNPACKED文件按CRTL＋G填001AA000，在HEX　WORKSHOP编辑菜单下选中选择块填入1AD0F0，然后粘贴保存退出  
四、修正入口点和输入表位置  
　　 起动揫PEDITOR，载入文件UNPACKED.EXE将入口改为001A172C，输入表位置改为001AA000，点重建输入表  
五、试运行文件，一切正常，OK收活路，其它你想搞什么你自己玩去，886
