[旧帖] [求助]关于脱UPX壳,请教个问题
0.00雪花
我看了"PYG论坛3周年庆典官方大礼包 礼物一"里的教程--第五课,泰来文件切割合并工具被加了UPX壳,我无法脱掉.
经PEID检测,结果为:UPX 0.89.6 - 1.02 / 1.05 - 1.24 -> Markus & Laszlo
本想用Quick Unpack脱的,我输入OEP:004016AC,结果弹出对话框提示:An invalid argument was encountered.
09:23:17 - Opened 泰来文件切割合并工具.exe
Quick self analyze.... unknown
PESniffer EP Scan: UPX v0.89.6 - v1.02 / v1.05 - v1.22
PEiD scanning... UPX 0.89.6 - 1.02 / 1.05 - 1.24 -> Markus & Laszlo
09:23:24 - Unpacked file hasn`t been created
09:23:24 - Done
后来用第四课教的手动脱壳的方法,还是不行,我无法修复.

再按F8两次就是JMP 跳，来到这里
004016AC 68 C08D4000 push 泰来文件切割合并工具.00408DC0 ; OEP
004016B1 E8 F0FFFFFF call 泰来文件切割合并工具.004016A6 ; jmp to MSVBVM60.ThunRTMain
然后我用lordPE,进行DUMP,不能运行.接着用ImportREC修复.OEP输入000016AC,点IAT AutoSearch,确定,然后,size输入00001000,点Get Imports,结果上面的框子,显示N多-------valid:NO.
请问,我该如何修复啊?
