PEID 一查， Nothing found * ,奇怪了，原因自己分析是没修复IAT表的缘故，真确与否还请诸位帮忙，由于明天要考试，所以暂且弄到这里了。
这是我手脱的第一个壳，心情自然甭提有多高兴了，虽然可能在高手眼中是 张飞吃豆芽，呵呵~~
在次十分感谢fly等诸位的大力帮忙，谢谢！
顺便插一局，新手嘛，所以刚才还不知道怎么dump，说出来让大家happy一下，新年了，祝大家天天有个好心情！
About how to dump
首先光标停留在
0058A00C 55 PUSH EBP
这一行，F2，确定，F9。打开 LordPE ，注意此时不要关闭OD，选择进程，右键 dump full 选择一个保存路径和文件名称即可。
【总结】
脱 ASPack 2.12 -> Alexey Solodovnikov
用 od 载入 .exe后 ,来到程序入口点,一般后面紧跟 2个 call 指令,跟踪直到 出现了 POPAD 这一句,程序就在附近, 看见2个 RETN ,第二个处,F7,变来到了入口点,00?????? 55 push ebp 处即可dump了!
