Your goal in each of these levels is to find the password which will lead to the congratulations screen displaying the second password.

Thanks, but your goal is vague.

 

For level 8, you can force the password generating loop after patching the hashchecks, but no way to verify this "2nd password"

Sorry for being unclear on this one, you must find the correct first password, you cannot simply patch and get the success response, you must get the correct serial.

For Level 8

 

How we are supposed to find the correct serial if the entered serial is getting compared with a random one on each run?

Example

mM4G2KCYMhhj?wZ8L[Q:
\\5@VVv[q123dJ0zf}2\\S
E<khxXgylMoEKR]^WsTN
 

So a serial is valid only 1 time

Once the app is terminated it will generate a new random valid serial using srand/rand functions. So no use of this without patching.

What i meant is, that is not the correct solution.

You need to do something else.

683c3e0008053e000f0002008b010c0053006f006600 is not the correct password.

Well then the correct pass is this i guess.

Yes, that is correct.

You shouldn't put the good/bad message before the relevant checks. It only confuses the reverser, because we then have to guess what we're looking for, which is very unrealistic. No patching rule is also unrealistic.

 

Try to make your future ones have a clear goal. Like get a good msg box, or unpack it, etc.

 

PS - You left symbols in the .exe. In devcpp, go Project->Project Options->Compiler->Linker->Strip Executabe - Yes : )

[tehpro]

No one wants to try the rest ?

[atom0s]

All of these are from a challenge site, rather than have others do the work for you why not figure out how to do them yourself?
