Hello, guyz this is my new challenge for you all.

Your task is to find a valid serial for the name: pownboxforum

Finding the correct serial should not be difficult.

However, there are some anti-reversing tricks that may give you some trouble, that is why I rated "3", since for a couple of them luck cannot help...

You should send a detailed report about the anti-reversing tricks you dealed with and the way you bypassed them.

Just a valid serial will not be accepted!!!

Learn..and help the other to learn!

Enjoy,

H_T_P

Nice antidebug trick with OutputDebugString. All other tricks can bypass with anti-antidbg plugins.

Why do ppl always post serials?

Unless an anti-spoiler-system is implemented, stop doing this ... write a tutorial and submit it...

Dear Anicona you are right but unfortunately it seems that nobody reads the instructions/rules...

Yes, perhaps it was not the best solution, to put the serial here (even though i don't agree with you) still, single serial is not the solution. I listed out neither the antidebug used in the cm nor the algorithm. Even the serial is coded binary, so you have to check it on your own.
The problem is - why you read the comments BEFORE you actually solve the challenge ?

Many thanx to all the people that dedicated some time on this challenge.
I know that some of you may think that it is over-rated in terms of difficulty, however I take as consideration always the beginners and believe me, a beginner would not have done anything of what you did in order to bypass the anti-reversing stuff.
In any case I hope you enjoyed it.
