004254C9 55 push ebp
004254CA 8BEC mov ebp,esp
004254CC 83EC 44 sub esp,44
ACProtect之寻找丢失的Stolen Code
关于Stolen Code的简单解释
1。设置异常（忽略除INT3中断的所有异常），隐藏OD
2。来到入口点，F9运行
004AC000 > 60 pushad //记住这个
004AC001 4E dec esi
004AC002 D3D6 rcl esi,cl
004AC004 4E dec esi
004AC005 66:D3E8 shr ax,cl
004AC008 4E dec esi
004AC009 8BC3 mov eax,ebx
004AC00B 48 dec eax
3。程序中断在这里
004BAB23 90 nop //这其实也是最后一次异常
004BAB24 64:67:8F06 0000 pop dword ptr fs:[0]
004BAB2A 83C4 04 add esp,4
004BAB2D 60 pushad
004BAB2E E8 00000000 call NetClean.004BAB33
004BAB33 5E pop esi
004BAB34 83EE 06 sub esi,6
004BAB37 B9 5B000000 mov ecx,5B
004BAB3C 29CE sub esi,ecx
004BAB3E BA 09E5B87E mov edx,7EB8E509
004BAB43 C1E9 02 shr ecx,2
004BAB46 83E9 02 sub ecx,2
004BAB49 83F9 00 cmp ecx,0
004BAB4C 7C 1A jl short NetClean.004BAB68
004BAB4E 8B048E mov eax,dword ptr ds:[esi+ecx*4]
4。看堆栈，找SE句柄，数据窗口跟随，下硬件访问断点，shift+F9
5.下断，再次SHIFT+F9，下断，再次SHIFT+F9，取消所有断点，直接F4到RETN处
6。下d 12ffc0，下硬件断点。SHIFT+F9。
7。记下Stolen Code 。
004C9B31 55 push ebp
004C9B32 8BEC mov ebp,esp
004C9B34 6A FF push -1
8。找到内存，在00401000处下断，F2，SHIFT+F9。
004431F9 68 D8B24400 push NetClean.0044B2D8 //这里其实是假的OEP！！
004431FE 68 B4334400 push NetClean.004433B4 ; jmp 到
00443203 64:A1 00000000 mov eax,dword ptr fs:[0]
00443209 50 push eax
0044320A 64:8925 0000000>mov dword ptr fs:[0],esp
00443211 83EC 68 sub esp,68
00443214 53 push ebx
9。写入真实的代码！！
10。OD插件脱壳，注意，修正OEP地址！！
11。IR修复，用等级3。不能修复的CUT掉。抓取修复。程序还是抱错！
12。做下处理。来到壳的入口。也就是第一步记下的地址
CTRL+G，004AC000
13，写入真的OEP代码。
14。Lord PE修正入口点
15。保存，脱壳成功！
手脱ACProtect V2.0.X
第一个程序：
1.下断：bp GetCurrentProcessId，F9
2。
7C809940 > 64:A1 18000000 mov eax,dword ptr fs:[18] //断在这
7C809946 8B40 20 mov eax,dword ptr ds:[eax+20]
7C809949 C3 retn
3。用Lord PE查OD的PID。
4。把2中的代码改为
7C809940 > B8 3C150000 mov eax,153C （当然，PID号每次都会变）
7C809945 90 nop
7C809946 90 nop
7C809947 90 nop
7C809948 90 nop
7C809949 C3 retn
5。下断，BP GetModuleHandleA，F9
6。
7C80B6C1 > 8BFF mov edi,edi //断在这
7C80B6C3 55 push ebp
7C80B6C4 8BEC mov ebp,esp
7C80B6C6 837D 08 00 cmp dword ptr ss:[ebp+8],0
7C80B6CA 74 18 je short kernel32.7C80B6E4
7C80B6CC FF75 08 push dword ptr ss:[ebp+8]
7C80B6CF E8 C0290000 call kernel32.7C80E094
7C80B6D4 85C0 test eax,eax
7C80B6D6 74 08 je short kernel32.7C80B6E0
7C80B6D8 FF70 04 push dword ptr ds:[eax+4]
7。来到内存，在CODE断下内存访问断点，F9运行，出现NAG窗口，点确定后，来到OEP！！！
00402150 55 push ebp //OEP！！
00402151 8BEC mov ebp,esp
00402153 83C4 F0 add esp,-10
00402156 53 push ebx
00402157 B8 10214000 mov eax,ACP_Feed.00402110
0040215C E8 4FFCFFFF call ACP_Feed.00401DB0
00402161 68 C4214000 push ACP_Feed.004021C4 ; ASCII “ACProtect Feedback Form”
00402166 6A 00 push 0
00402168 6A 00 push 0
8。脱壳，修复。用等级3！或者手动找MessageBoxA
9。抓取，脱壳成功！！
第二个程序：
1。忽略除内存访问的所有断点，隐藏OD
2。F9，找SE句柄，数据窗口跟随，下内存访问断点
3。SHIFT+F9，F2，再SHIFT+F9，F2，再次SHIFT+F9，取消所有断点。
4。运行到RETN
5。打开内存，0401000处下F2断点。SHIFT+F9
6。来到假的OEP。
7。修正代码
8。脱壳，修复
9。OK~！！脱壳完成

1、忽略所有异常
2、打开内存镜像，在.rdata处F2，SHIFT+F9
没有.rdata用.idata

20、用工具申请一个新的区段
记下起始的地址：0043E000
21、OD打开创建完后的。找到0043E000，粘贴入代码，保存
记住，后面得加跳向假OEP的代码！！
JMP 0040305C
22、修正入口点
手脱ASProtect1.23
1.忽略除内存访问的所有断点，隐藏OD
2。来到最后一次异常
3。RET下断，运行到这。
4。下硬件断点 hr XXXX或在00401000下断，运行
5。直达OEP
6.修复，借助辅助工具
手脱ASProtect 1.2
ASProtect 1.2 / 1.2c-> Alexey Solodovnikov
最后一次异常
在RET处下断
内存镜像00401000下断
直达OEP！！
脱壳，修复。
手脱ASProtect1.23 RC4
版本的判断：
判断版本：
ASProtect 1.23 RC4 按shift+f9键26次后来到典型异常，在最近处的retn处设断，跳过异常，f8步跟就会来到foep。
ASProtect 1.31 04.27 按shift+f9键36次后来到典型异常，在最近处的retn处设断，跳过异常，f8步跟就会来到foep。
ASProtect 1.31 05.18 按shift+f9键40次后来到典型异常，在最近处的retn处设断，跳过异常，f8步跟就会来到foep。
ASProtect 1.31 06.14 按shift+f9键38次后来到典型异常，在最近处的retn处设断，跳过异常，f8步跟就会来到foep。
1、忽略除内存访问的所有异常，隐藏一下OD，SHIFT+F9 26次后来到最后一次异常

2、在RETN处下断，SHIFT+F9，取消断点
3、在堆栈窗口找显示程序名的下面2行，下HR 12FFA4
4、一直F8，到这里

10、补上代码，脱壳，修复
ASProtect之以壳解壳
一些简单的以壳解壳理论
实战以壳解壳
1、忽略除内存访问外的所有异常，SHIFT+F9，来到最后一次异常
2、来到最近的RETN
3、打开内存镜像，在00401000处下断，SHIFT+F9，到达假OEP，记下
004F27CF FF15 9CC25200 call dword ptr ds:[52C29C]

4、重新来，重复上面1和2步，下hr 0012ff68，SHIFT+F9，取消断点，F8，来到最佳的以壳解壳地方
00C85793 BB A2000000 mov ebx,0A2 //最佳地
00C85798 0BDB or ebx,ebx
00C8579A 75 07 jnz short 00C857A3
00C8579C 894424 1C mov dword ptr ss:[esp+1C],eax
00C857A0 61 popad
00C857A1 50 push eax
00C857A2 C3 retn
00C857A3 E8 00000000 call 00C857A8
00C857A8 5D pop ebp
00C857A9 81ED 4DE14B00 sub ebp,4BE14D
