【目 标】: 应作者要求，这里不贴上软件名【工 具】:Olydbg1.1(diy版)、LORDPE、ImportREC1.6F 【任 务】:分析外壳 【操作平台】:Windows 2003 server 【作 者】: LOVEBOOM[DFCG][FCG][US]【相关链接】: ......【简要说明】： 脱ACPROTECT的壳并不多，以前最多只是大概的脱一下，对壳有流程并没有多少认识，前几天帮朋友了一下这个软件，也许 是我水平太菜了，也许是脱这个东西脱的比较少，在脱这个软件花了我很多时间，搞的过程中还很容易出小问题。还有一个原因是脱了一下新版的ASPR 2.X stolen code让我看到头疼，虽然坚持了，但现在还有一小部分没有解决:-(。没办法两个都壳都是难搞的，本着看aspr的东西稍微多了点，因此牺牲了睡觉时间，帮自己补了下课。壳的思路比较新，边执行边解壳，解压一段执行后又还原回去，代码替换，EMBEDD protect等等。这么有吸引力，当然不要错过了。因为我对RSA无KEY怎么突破之类的没有一点了解，再者也没有见过软件用RSA lock code.，所以这次没有分析KEY相关的东西。我这次和以前的文章有点不同，这次为了更细的分析出壳的各模块功能，把相关的模块放在独立的地方，也不像以前那样，插来插去的。不是很方便自己查看。也很久没有细细的去品尝壳了。也是该“享受”一下。【详细过程】:写在前面的，你只是想知道怎么脱壳的话，那么这你可跳过这一章节，这一章节是分析壳的每个部分，是比较漫长的。如果你完全分析好了，后面脱就简单了。 由于是一步一步的走，所以不用什么特别的设置了。唯一一点就是要很磨得下去。打开OD，忽略全部异常。准备眼睛再度近视几度。泡上一杯水，然后开始这次的旅程：为了防止壳的检测，这次我没有去除花指令直接动态跟踪分析了下。0057C000 > 60 PUSHAD ; EP0057C001 E8 01000000 CALL 0057C007 ; 程序一开始就反复解壳代码0057C006 - 72 83 JB SHORT 0057BF8B0057C008 04 24 ADD AL,240057C00A 06 PUSH ES0057C00B C3 RETN0057C00C 85C3 TEST EBX,EAX0057C00E 76 01 JBE SHORT 0057C0110057C010 4B DEC EBX0057C011 87D8 XCHG EAX,EBX0057C013 E8 01000000 CALL 0057C0190057C018 - 76 83 JBE SHORT 0057BF9D......0057C204 64:FF30 PUSH DWORD PTR FS:[EAX]0057C207 64:8920 MOV DWORD PTR FS:[EAX],ESP0057C20A CC INT30057C20B 90 NOP0057C20C F8 CLC0057C20D 90 NOP0057C20E FC CLD......0057C29F 64:8F05 0000000>POP DWORD PTR FS:[0] ; 直接F2，然后执行到这里，0057C2A6 83C4 04 ADD ESP,40057C2A9 7C 03 JL SHORT 0057C2AE ; 这里是开始还原的地址0057C2AB 7D 01 JGE SHORT 0057C2AE......0057C436 4A DEC EDX0057C437 ^ 0F85 7FFFFFFF JNZ 0057C3BC ; 没有解压完则跳回继续解压0057C43D EB 01 JMP SHORT 0057C440壳一开始就通过几个异常来循环解压出壳的代码。解压的方法很简单的：MOV EBX,DWORD PTR DS:[EAX]XOR EBX,EDIROR EBX,1FADD EAX,4XOR EBX,DWORD PTR DS:[EAX]ADD EAX,-4MOV DWORD PTR DS:[EAX],EBXXOR EDI,45BA1300继续:......0057C7F8 64:8F05 0000000>POP DWORD PTR FS:[0] ; 0012FFE00057C7FF 83C4 04 ADD ESP,40057C802 E9 BB4A0100 JMP 005912C2 ; 全部解压完了跳去执行壳的代码......005912C2 E8 39AEFFFF CALL <sub_GetEBP >
