| obnoxious 14. Aug 2008 | why does the About say "write patch....."? |
|---|---|
| MulleDK13 14. Aug 2008 | Maybe because you have to patch it? |
| simonzack Moderator 14. Aug 2008 | don't think so. It'll be too easy, I think it may be because his English is confusing |
| Xspider 14. Aug 2008 | maybe you can patch it to display the password! |
| simonzack Moderator 15. Aug 2008 | lol, that's impossible :p |
| Zaphod 15. Aug 2008 | A tricky one, this crackme! I think I know exactly what's going on, there are several ways to get the Goodboy, but they all need 5 bytes - and we only have 4. I'm still scratching my head... |
| _raven 16. Aug 2008 | @Zaphod: There is a 0xFF after the 4th byte, so you have 5 bytes. |
| obnoxious 16. Aug 2008 | eh! guys i was just curious why he wrote that way even though he wont accept pathed solutions. btw it is easily solvable... stay tuned you will see a detailed tut on it :) |
| Zaphod 16. Aug 2008 | raven, I know about the 0xFF byte ( and what it can do ), but I can't give eax a certain value using only 4 bytes. I have tried a lot of things like xchg and lods and whatever, but I always miss one byte. |
| obnoxious 16. Aug 2008 | need some help Zapod????? |
| Zaphod 17. Aug 2008 | obnoxious, I'm still searching for the right bytes, but if I don't find them, I'll just have to wait for your tutorial :) |
| obnoxious 21. Aug 2008 | @Zaphod i hope every thing is clear now :) |
| Zaphod 21. Aug 2008 | obnoxious: yeah, all clear now :) damn it, I just never thought of jumping outside the code section and back again - very neat, indeed :) |
| Xspider 22. Aug 2008 | yeah ^^ btw thx obnoxious your solution was 100% clear xD |
| obnoxious 23. Aug 2008 | Glad i could help :P |
