D4ph1 26. Aug 2006 | I found the key for my name but it only works when debugger is on. when i run it all alone the same serial doesnt work....is this a bug? |
D4ph1 26. Aug 2006 | Ooops...now i see...A keygen is on the way ;) |
mucki Author 26. Aug 2006 | sorry D4ph1 but it's not a bug - it's a trap. |
geeko 26. Aug 2006 | My keygen was rejected. Does anyone know why? |
zairon Moderator 26. Aug 2006 | D4ph1, you are not the only one falling in the trap... geeko did the same :) |
D4ph1 26. Aug 2006 | I cant keygen this. someone submit a tut plz :( |
mucki Author 26. Aug 2006 | hint: the algo is simple but only the last digit is a bit tricky (calculated from the previous number not from the name) |
Zaphod 27. Aug 2006 | It would be easy to write a selfkeygen because the full serial (including the last digit) is in memory at some point, but as mucki says, this last digit is rather tricky. Too tricky for me, I'm afraid, but I'm still working on it... |
D4ph1 27. Aug 2006 | i make the keygen and when i have time i will submit the tut. great work mucki ;) |
cyclops Moderator 28. Aug 2006 | Every one is falling into the trap.... i think my self keygen works.... |
Zaphod 29. Aug 2006 | I haven't entered the trap part at any time - I am always sent to the right serial-calculation part. Then I thought, oh, of course, that's because I have the HideDebugger plugin! But no, I removed the HideDebugger.dll and the HideDebugger.ini files, but still I come to the correct serial calculation part. I wonder why that is - any suggestions? |
mucki Author 29. Aug 2006 | which debugger do you use? |
Zaphod 29. Aug 2006 | Olly - Heh, first I wrote "Olly" and nothing more - then I was told that was too short a message, so now I write this :) |
mucki Author 01. Sep 2006 | I have also tried it. If HideDebugger.dll is in the Olly-dir nothing happens otherwise Olly falls into trap. |
Zaphod 02. Sep 2006 | Yeah - that's how it SHOULD be, but not on my computer. Mysterious... |
polizei 27. Feb 2007 | perhaps i missed the "trap", but i just kept jmping around it. i tested while not debugging and my keygen still worked. i'll right a tut to accompany it soon. |
hound 27. Feb 2007 | Lol, not sure how you could miss it. The check happens right after the GetWindowText call..... Anyway, cool idea :D |
