Unpacking SafeDisc v2.90.40 -- 樱花大战3简体中文标准版(如果你的HP不是满的话,还是先去喝几个血瓶吧)
[工具]:ODbyDYK,ImportREC,LordPE
大家都知道SafeDisc好一个用驱动来欺负我们的OD,但是我们真的会让OD被他欺负吗?
用OD载入Sakura3.exe。
020B305E > 55 push ebp <-OD停在了这里
020B305F 8BEC mov ebp, esp
020B3061 60 pushad <-大家看,多么友好的提示。
020B3062 BB 5E300B02 mov ebx, offset Sakura3.<ModuleEntryPoint>
020B3067 33C9 xor ecx, ecx
020B3069 8A0D 3D300B02 mov cl, byte ptr ds:[20B303D]
020B306F 85C9 test ecx, ecx
向下找POPAD。一共找到了三个大家可以看看哪个比较象。
020B30BA 85C9 test ecx, ecx
020B30BC 74 09 je short Sakura3.020B30C7
020B30BE 61 popad
020B30BF 5D pop ebp
020B30C0 B8 00000000 mov eax, 0
020B30C5 ^ EB 97 jmp short Sakura3.<ModuleEntryPoint>
020B30CD FFD0 call eax
020B30CF 61 popad
020B30D0 5D pop ebp
020B30D1 EB 46 jmp short Sakura3.020B3119
020B30D3 807C24 08 00 cmp byte ptr ss:[esp+8], 0
020B3115 61 popad
020B3116 1360 0D adc esp, dword ptr ds:[eax+D]
020B3119 - E9 09BF5FFE jmp Sakura3.006AF027
020B311E CC int3
然后你小按几下F8,就会发现刚才的入口点被修正成了
020B305E >- E9 C4BF5FFE jmp Sakura3.006AF027
020B3063 5E pop esi
020B3064 300B xor byte ptr ds:[ebx], cl
020B3066 0233 add dh, byte ptr ds:[ebx]
然而,事实证明,真正有用的是020B3119那里的跳转。
先说一下safedisc的运做过程,先把自己需要的连接库解压到临时目录,写为*.tmp文件。然后LoadLibrary。
再跳到载入的~df394b.tmp模块进行调试器检测,加载光盘检测模块,解压缩大部分主程序,再进行光盘检测向主程序写入剩下的一些数据,返回。
下面进入正题:
对 IsDebuggerPresent 下断(软件/硬件断点都行,但是我选择硬件断点,感觉保险些。下面相同)。显得有些多此一举,用插件能避开的还搞那么麻烦,而且我也用插件避开了,但是我们需要定位后面的调试器检测。
断下后取消硬件断点返回到这里:

注意:由于我的OD是修改版,所以只需要改一个跳转。你自己调试时,务必不能让其中任何一个jnz跳下去。改的时候,只能修改标志位Z=1。因为后面这个库还有模块完整性的检查。

小结:现在我们第一次的路程结束了。我们得到了什么?
我们得到了避开调试器检测的方法和调用驱动的过程以及入口点的位置,但是我们却没有得到dump文件和完美的IAT。
继续。
我们现在需要正确代码段。因为如果你细心的看下代码的话,你会发现一些这种代码。
00688CF2 85C0 test eax,eax
00688CF4 CC int3 <-正常的程序会有这种东西吗?
00688CF5 CC int3
00688CF6 8B4424 10 mov eax,dword ptr ss:[esp+10]
00688CFA 8B4D 04 mov ecx,dword ptr ss:[ebp+4]
00688CFD 3BC1 cmp eax,ecx
00688CFF ^ 0F8C D4FEFFFF jl sakuara3.00688BD9
但是怎么得到呢?不能通过调试器,OD不能进驱动,SI被防得又太严。
其实非常的简单,我们只需要运行游戏,在进入游戏后按下windows徽标键强行弹出,再用LordPE把他的代码段dump下来就行了。因为这样做,我们没有对他作过任何手脚,所以它就会安心的写下所有的代码。上面的两个CC也会被一个短距跳转所取代。但后我们只要在OD到达入口点前一点的位置把他作为备份载入即可。
下面是IAT了。在现在的入口点我们可以看到部分Call []后面并没有写出是什么函数。入口点之后第一个这种调用应该是GetVision。那么我们进入看看:
02F43CE4 68 A310EABF push BFEA10A3
02F43CE9 9C pushfd
02F43CEA 60 pushad
02F43CEB 54 push esp

1005474A 8B65 0C mov esp,dword ptr ss:[ebp+C]
1005474D 61 popad
1005474E 9D popfd
1005474F C3 retn
我们在第二个SetEcent后的retn处下断,运行。停下后看看堆栈:
0012FF44 77E5D142 kernel32.GetVersion <-果然
0012FF48 006AF053 返回到 sakuara3.006AF053 来自 02F43CE4
0012FF4C 77F517E6 返回到 ntdll.77F517E6 来自 ntdll.77F78C4E
0012FF50 77F51778 返回到 ntdll.77F51778 来自 ntdll.77F517B5
这就是SafeDisc对IAT加密形式中一种。尽管这种方法很难手工修复,但是我们发现还是有些IAT是没有被加密的。所以我们就要从这里下手。
重新开始。我们先对其中一个没加密的IAT的位置下硬件断点(软件断点不能下在内存单元上,内存断点会被它在修改内存属性的时候废掉)。运行,避开检测,得到了地址。然后再重来跟踪这个地址,最后我们得到了这些代码。
(这串代码并不好找,这里给大家一个带有人品问题的找法。用你的停在上面提到的要修改的避开调试器检测的跳转的地址+4FAC0,然后g 这个地址之后,在上下的代码段中找一找,一般就能找到了。用NFSU2试了下,还是比较接近的。)

100540EA ^ EB 9C jmp short ~df394b.10054088
于是我们修改100540B8修改为Xor eax,eax,然后运行到入口点,我们发现了几乎完美的IAT。。。
打开ImortREC取得IAT,发现还有1个无效的指针:[1ec8064]=02f310e7。
我们查找命令Call [1ec8064]。找到006ac1c7。新建EIP跟的这个是GetTickCount。
现在IAT修复了。似乎所有的任务都完成了。但是现实却不是这样,SafeDisc还用jmp [eax],jmp ********加密了一些函数和过程的调用。
小结:到这里第二步也完成了,我们得到了几乎完美的文件。
下面就剩文件的修复了,继续。
今天下午,我着手开始修复代码,一开始我以为要修复的代码不会很多,所以就手工一个个的修复。
我们打开两个OD,一个直接走到入口点(一下简称B),另一个修复IAT后再走到入口点(一下简称A)。
然后我们进入B的入口点之后的第一个调用,就是前面提到的GetVision的调用,到达这里
1005472F E8 AA14FDFF call ~df394b.10025BDE
10054734 59 pop ecx
10054735 F0:FF0D 646C0610 lock dec dword ptr ds:[10066C64]

Patch之后

10054747 90 nop
10054748 90 nop
10054749 90 nop
然后运行,暂停时堆栈的第一行就是IAT的名称和地址。
我们在进入A,比较一下这两个IAT是不是一样,不一样就在IAT表中找一个和他一样的,再把这个调用的内存地址修改成我们需要的。为什么要这样呢?因为SafeDisc加密的部分IAT调用不具有唯一性。就是说在不同的地方调用同一个内存地址,所获得的IAT并不一定是一样的。
我们就从00401000的地方开始。查找二进制字符FF15,然后开他调用的内存地址,如果是01EC8XXX那就是我们要的。在B中的那里新建EIP,然后运行,断下时和A中显示的IAT作一下比较,不同的就在A的IAT表中找一个和B中是计算出来的IAT一样的内存地址改写到A中的调用里去。然后循环处理整个代码段知道找不到为止。然后还有E9????01(要是跨段跳的那种),和一个Call的重定向。
不过做了几个之后,我发现自己错了,结果我一下午的时间就这样报销了。不过大家可以看看修复过的地方吧,应该会有某种比较深刻的印象的。。。

全部搞完之后,我决定,如果下次还要搞这种东西话,我一定要写Patch代码。还好樱花大战3的代码段只有2C700H。。。(如果哪位高手写出来的话,我也想要一份^_^)
现在我们要把A的00401000段和01EC8000段备份下来。不然以后要在用的话会死人的。
小结:第三部分完成了,我们把能看到的代码全部修补了,下面就等我硬盘有空间的时候把游戏装上测试了,毕竟这个游戏还是有3G那么大的。
神啊,祝福我把~~~~!!!
