| Fergo 07. Nov 2006 | I don't know if this is a bug of something, but the program crashes when I close it ( it doesn't terminate after the "animation" ). |

| BaKaE 08. Nov 2006 | @fergo works on my pc @mucki really nice tricks can i patch the smartcheck check ?? |
| mucki Author 08. Nov 2006 | patching is allowed to enable the button and to remove the tricks/animations but no good-boy-jump and selfkeygen |
| ProTreeBrain 13. Nov 2006 | For mucki: I don't understand if it is a bug/ program is unclosable. It must be terminate with bruteforce. |
| mucki Author 13. Nov 2006 | i had no problems but fergo said the same, so i will check it when i have time. |
| Ank83 16. Nov 2006 | Hm... I have problems with this one. I killed the two procedures for protection, I enabled the button and went to password generating procedure. Now in the first part the app gets the sum of Asc number for each char in the name, than from the sum it takes out the sum of Asc numbers of the name of the local PC. Now goes the part that I dont understand, but I'm, still working on it. In the mean while I run the target in SmartCheck and there is notice that our entered serial is compared with some serial. When I enter the serial that popuped in SC - BADBOY message. Hm ? Is someone working on this one ? Need some help. Best Regards Ank83 |
| mucki Author 16. Nov 2006 | hi Ank83, you are very close to solve it, only two simple operations are missing. then there are a few lines of confusing crap code - sorry for that, maybe i submit an improved one soon also with bugfix. (next one will be better again / not in vb) thx that you are still trying |
| binbinbin 19. Nov 2006 | 97611fde0bc4e3344f872df926d548cb I found this |
| Ank83 19. Nov 2006 | binbinbin I think that this target has no valid serial. |
| mucki Author 20. Nov 2006 | you need a plugin against isdebuggerpresent detection |
| HMX0101 20. Nov 2006 | Very easy... I fished serial for my name/computer name ;) btw, i don't know why exists a md5 implementation in the crackme and you don't use it? |
| mucki Author 20. Nov 2006 | md5 hash will be calculated if you fall into isdebuggerpresent-trap |
| HMX0101 20. Nov 2006 | Ahh, but isn't important? |
| mucki Author 20. Nov 2006 | no, but it works as you see above |
| movzx 22. Nov 2006 | nice trick.. :D im still searching for the info about ZwQueryInformationProcess do you have a document like Win32API help file that describes the ntdll.dll function?? thx. |
