| idid231 08. Jan 2013 | Mov,Xor, ECX, EDX.. i don't know how to jump direct and remove un-use code. If we follow jump by jump command we must spend pretty much time to reverse longer code, not good. |
| 3ton 08. Jan 2013 | KEY DB "********r1d!",0 MOV EAX DWORD PTR [KEY] MOV ECX DWORD PTR [KEY+4] XOR EAX, 0F45A675Dh XOR ECX, 04DDAFA31h ADD EAX, ECX CMP EAX, 0BAE3DC73h MOV EAX DWORD PTR [KEY] MOV ECX DWORD PTR [KEY+4] XOR EAX, 0AADD357Dh XOR ECX, 044FAFC3Ch ADD EAX,ECX CMP EAX,0F23F2C88h MOV EBX, DWORD [KEY+8] CMP EBX,21643172h ;"r1d!" |
| idid231 08. Jan 2013 | I knew its algorithm. I just don't know how to split it out from junk codes. Tell me how did you do 3ton, please. |
| demoth 08. Jan 2013 | I written a little program for deobfuscate this crackme. You can see deobfuscated crackmes here: http://rghost.ru/42840075 |
| demoth 08. Jan 2013 | 3ton, how you understand what MOV EAX DWORD PTR [KEY] MOV ECX DWORD PTR [KEY+4] XOR EAX, 0F45A675Dh XOR ECX, 04DDAFA31h ADD EAX, ECX CMP EAX, 0BAE3DC73h MOV EAX DWORD PTR [KEY] MOV ECX DWORD PTR [KEY+4] XOR EAX, 0AADD357Dh XOR ECX, 044FAFC3Ch ADD EAX,ECX CMP EAX,0F23F2C88h it is checking "Hello wo"? Just guessed? |
| demoth 08. Jan 2013 | Mmm... I'm idiot. There are many collisions, for example: HelDo wG JetLm oO HOlLoNwO JGldmFwg etc. But message is incorrect for them. |
| idid231 09. Jan 2013 | hi demoth, can i have your source of deobf program? I need your ideal to know how to debof this crackme. |
| andrewl.us Moderator 09. Jan 2013 | two solutions accepted, and neither uses a deobfuscator that emits a cleaner crackmer demoth, submit a solution with your deobfuscator! |
| ForFun 09. Jan 2013 | @bike: Excellent tut !! |
| 3ton 26. Jan 2013 | My script for deobfucate crackme. http://rghost.ru/43327252 |
| idid231 27. Jan 2013 | Thank you guys for the excellence tut and scripts. |
| kiTo 08. Apr 2013 | 3ton: Why post the answer without a solution? Thats just plain stupid. "Check me out, I know the answer but will not share!" |
