加壳方式：Armadillo 3.78 -> Silicon Realms Toolworks
破解工具：OllyDbg v1.10原版，ImportREC 1.6 Final，LordPE
脱壳作者：夜凉如水
老规矩忽略所有异常,在添加以下几个:
C0000005(ACCESS VIOLATION)
C000001D(ILLEGAL INSTRUCTION)
C000001E(INVALID LOCK SEQUENCE)
C0000096(PRIVILEGED INSTRUCTION)
用ＯＤ载入，先下OpenMutexA断点shift+F9运行

在401000处新建起源,右键－》此处新建EIP
F9运行，再次中断在OpenMutexA处，取消断点。
再次Ctrl+G 401000
撤消刚才做的选择，右键-》撤消选择
2、下GetModuleHandleA断点F9运行
7C80B529 k> 8BFF mov edi,edi断在这里,取消断点
7C80B52B 55 push ebp
7C80B52C 8BEC mov ebp,esp
7C80B52E 837D 08 00 cmp dword ptr ss:[ebp+8],0
7C80B532 74 18 je short kernel32.7C80B54C 再次下断
按F9，注意堆栈

此时，取消断点，ALT+F9返回

第三、下GetCurrentThreadId断点 按F9运行
注意看堆栈
001270D8 66001E3A /CALL 到 GetCurrentThreadId 来自 66001E34
001270DC 00000001
001270E0 66001C1E 返回到 66001C1E 来自 66001DE6

0012D76C 04E84B97 /CALL 到 GetCurrentThreadId 来自 04E84B91 //返回时机
取消断点ALT+F9返回这里：
04E84B97 50 push eax //f8 f7跟踪
04E84B98 FF75 FC push dword ptr ss:[ebp-4]

04E9CA54 2BCA sub ecx,edx
04E9CA56 FFD1 call ecx F7进入飞向光明之巅 ; TJMan.0042C4D2
0042C4D2 55 push ebp //oep=0042C4D2-400000=2C4D2 用LordPE Dump！
0042C4D3 8BEC mov ebp,esp
0042C4D5 6A FF push -1
0042C4D7 68 F8244300 push TJMan.004324F8
0042C4DC 68 36C64200 push TJMan.0042C636 ; jmp to msvcrt._except_handler3
0042C4E1 64:A1 00000000 mov eax,dword ptr fs:[0]
0042C4E7 50 push eax
注意不要关OD，直接打开ImprotREC否则不能修复成功，选择我们要脱的进程。然后输入OEP,2C4D2。自动搜索IAT-》获取输入表，有一个假指针-》点显示无效函数-》右键-》剪切指针-》修复抓取文件
呵呵~~成功
