| XzzX 12. Oct 2007 | Nice and very easy crackme. You should include some anti-tampering check because stage 3 is really simple. |
| _raven 14. Oct 2007 | Yeahhh... I've done it! Solution is on it's way! |
| br0ken Author 14. Oct 2007 | Has anybody found the bug I talked about? It's real easy to find. |
| DigitalAcid 14. Oct 2007 | Is a crashing Olly a bug ? =) Another Olly edition said the code section was empty... |
| br0ken Author 14. Oct 2007 | There's no crash, within and outside Olly. I've tested it with the "standard" and the patched Olly on XP SP2. Which edition of Olly are you using? This isn't the bug I had in mind. Look harder ;) |
| sd333221 14. Oct 2007 | I have also submited solution long ago, but it takes years :-) |
| br0ken Author 14. Oct 2007 | It's an easy CM. Perhaps the mods are waiting, to give others a chance to try. Oh well, just wait a little longer. Finding the bug is an additional task. It's not necessary to do it. Anyway, here's a hint if you want to try, Once you've understood the serial generating routine, it's very easy to spot the bug. In fact, it was intentional ;) |
| br0ken Author 14. Oct 2007 | @ XzzX, Thank you for your comments. I'll keep it in mind. |
| TiGa 14. Oct 2007 | We're waiting a few days to leave a chance to more people to send in their solution since it is a very easy crackme. It has never been a speed contest and often, the first solution received is 2-3 lines long or lacks quality. Patch 00401073 to nop. Patch 0040404K to nop. Get Message Congratz. It doesn't explain anything, especially bad if the author says NO PATCHING in big capital letters. |
| DigitalAcid 16. Oct 2007 | Normally i'm using SLV/ICU mod (the crashing Olly in this case) with plugins. I tried FOFF Olly and it works then. But, my pc is a mess and i'm on XP SP1. |
| chaise 17. Oct 2007 | I think that i have found the bug There is a cycle of too in the loop which calculation the serial |
| noukeys 17. Oct 2007 | I solved yet, there is no bug in the crackme. Tomorrow i'm going to write a tuto and send my solution. sorry for my english. |
| sd333221 19. Oct 2007 | Nice, all three did almost the same :-) |
| br0ken Author 20. Oct 2007 | Congratulations to those who solved and to those who tried ;) A full report has been published on my blog site. |
| sd333221 20. Oct 2007 | I am stupid that I didn't understand what you wanted to say with "bug" :-) |
| sd333221 20. Oct 2007 | Maybe you should have called it security issues, then I would have found it earlier :-D |
| TiGa 22. Oct 2007 | I made a video solution and a "making of" video of the keygen. The forum has a new video website: http://video.reverse-engineering.net |
| br0ken Author 22. Oct 2007 | Nice video, I enjoyed watching it ;) |

| TiGa 30. Oct 2007 | Reading the solutions or watching the video should help you. |
| Andrey_Kolokol 30. Oct 2007 | How can I submit my solution? |
| TiGa 30. Oct 2007 | The submission of solutions is closed for this crackme. Try solving another one instead. |
| Robocop131313 19. Jul 2009 | Can somebody help me? I don't know where I can find the letters from the first password. I know it has to be PaSSw0rD because I read the solutions. But I can't find where they get the letters Q,b,...,E. Can you help me explain how they do that? |
| br0ken Author 21. Jul 2009 | Robocop, I'm assuming you are using ollydbg for debugging. Set BP at 004013F6 -> F9 -> Enter any 8 digit password -> Enter -> when olly breaks, right click on that opcode -> Follow in dump -> Memory address. You will the string QbTTx1sE in the dump (ASCII). |
