| DigitalAcid 28. Jun 2008 | The patching only applies to the serial, right ? Ps: got a working unpacked file. Some nice little tricks there. I hate IAT destroying/repairing =). |

| HMX0101 Author 28. Jun 2008 | @DigitalAcid: yep only applies to the serial :) Good job on unpacking ;P.. the harder is getting the serial, you'll probably get confused and leave it ;) If you need any hints, just ask me... :D |
| DigitalAcid 28. Jun 2008 | Yeah, the serial algo is pretty long and confusing idd O.o. Trying to figure out what's happening... |
| BeatriX 28. Jun 2008 | Avast! antivirus tells the file contains "Win32:Pakes-AJD [Trojan]". |
| HMX0101 Author 28. Jun 2008 | Crappy AV :PP.. it doesnt contains any malicious code ;) it detect as a virus because its packed... forget about virus alert for this one :D and good luck for everyone which its trying it :) |
| Ox87k 28. Jun 2008 | The crackme doesn't run on my machine, is it normal? I have XP SP3. |
| DigitalAcid 28. Jun 2008 | @Ox87k: It doesn't run untill it is unpacked. I found 2 serials that bypass the first check (there are 6), but I only found them by trial and error. I'm still trying to figure out how a valid serial can be created =). |
| Ox87k 28. Jun 2008 | @DigitalAcid: Thanks, i thought it isn't working because some error or something like that. ;) |
| Crosys 30. Jun 2008 | nice one hmx :) |
| HMX0101 Author 30. Jun 2008 | @Crosys: thanx mate.. :) long time without see you :D I forget to include in the readme... don't bruteforce it ;) there's a way to solve it without brute... :) |
| kao 30. Jun 2008 | I solved it in the "proper" way but seems that bruteforce would be the easiest way. :) If no one writes tutorial this week, maybe I'll do that - this crackme deserves it. :D Thanks for really nice crackme! |
| HMX0101 Author 30. Jun 2008 | Damn.. it was solved too fast :PP good job, kao ;) and thx for cracking this piece of crap :) hope you've enjoyed it! :) |
| DigitalAcid 01. Jul 2008 | If you think you made a piece of crap, I don't want to see your normal Crackme's =P. |
| HMX0101 Author 01. Jul 2008 | Hehe... all my crackmes are easy, just need the right knowledge ;) |
| HMX0101 Author 03. Jul 2008 | Good job guys! :) This crackme was defeated so fast :P (damn, i need some more harder :D)... I really liked Zairon solution... ;) And jE, you can't just solve a simple 6x6 equation system? lol... its not necessary to brute... but well... Thanx for owning this crap :) |
| jE! 04. Jul 2008 | No, can't bcoz don't know what is it! NO MORE MATH! NO MORE MATH! NO MORE MATH! :) |
| jE! 04. Jul 2008 | BTW, say me: at least, that pussy protection is done by you!? |
| DigitalAcid 04. Jul 2008 | Very nice solution, zairon. Nopping the jmp to get a working unpacked file is exactly what I did. It would have been too much work to fix it manually, so I searched a faster, easier way :). |
| andrewl.us Moderator 04. Jul 2008 | Nice to see another WinDBG'er :) |
| lgtngstk 25. Aug 2008 | I'm new at this and am finding this sorta difficult, but I just can't resist. |
| HMX0101 Author 26. Aug 2008 | Well done, TiedInBronzeChains! Nice sol :) |
| TiedInBronzeChains 08. Sep 2008 | Thanks for the nice words! I think that a good solution is a the best way to show that you completely solved the crackme :) |
