Hi all,
I need some help about finding serial numbers/registration codes using ollydbg.
Though i'm not a newbie(as a have patched a few programs) but i'm not an advanced cracker also. The problem is that some programs are hard to patch as
they have some restrictions(besides nagscreens) which after patching also don't
go.I have also read some tuts regarding finding serial numbers using ollydbg but they r not good enough. So i request the forum members to help me with some tuts or if they have some good tuts i request them to share them with me.

waiting for ur replies.....................

do some fucking work yourself, pencil, paper, trace, make notes, solve the puzzle, dont expect to be spoonfed by tuts all the bloody time, use the search button, search the net for info, see your sig.. follow it

On the softer side of the above reply, please do not take it to heart. You are, of course, very welcome here. We are here to assist, but at the provision that you do not ask us to do your work for you.

The idea to get replies to your questions is that you have to show that you have done some work rather than simply firing questions. Asking questions about "generic" things (like: I want to learn how to seed out serial numbers, I want to learn how to defeat dongles, I want to learn how to defeat encryption) will probably get you no responses. Or responses like the one above, that is rightly justified.

I'd suggest that since you have never got serial numbers before, but merely patched, and noting that newer programs are not like yesteryear's programs where the serial was compared in memory (unless its a really bad program), trying to "echo" serials will, most of the times, get you nowhere.

So the best bet is to study softwares that ARE old and that HAVE serial echos, like Winzip 5 to 7 and Mirc 5 to 6 (or some other software in that year). And run them with Ollydbg and see what happens.

Though, I would suggest that you first take a complete week OFF cracking. Simply get the Ollydbg HELP printed out, test out the commands with good ol' notepad and THEN decide to get cracking. Olly works in ways very different to softice and you generally need to get used to a particular way of working with a particular software before you can utilize it completely.

A simple tip. Most new programs are not registered by patching single conditional jumps. Other issues, like nag screens remaining, etc are still in the wild. You could use OTHER tools like resource editors etc to get them out of the way. But a disassembly, finding where the info is called, reversing them is still the best way.

And there is NO substitute for hard work (and sometimes, extremely mundane too!) So as someone said long ago, pick a rainy day, give yourself time, and try breaking old programs first.

yeh mebe i was a bit harsh, i just hate the 'i learned from tuts and now i cant find the byte pattern any more, what do i do' sort of questions as people have to realise that whilst some tuts go into detail, specific byte patterns etc they are intended (most times) as an example, a way of showing what method to employ to crack the protection, not a spoon fed 'heres how to crack x,y,z' solution

On a funnier note, you can read the following post on msgboard as I successfully (though somewhat to the humor of everyone) try to explain why its important to understand the PRINCIPLE behind the tutorial and not the code and addresses itself.

Hm. Come to think of it, maybe the mods can use that JACKET definition as part of FAQ for why the problem often crops up (the problem: I've read tuts and followed the code, but my address is different. Help!)

hxxp://www.crackmes.de is perfect place for you. There you can find a lot of crackmes and tutorials how to crack them. Also you can try hxxp://cracking.accessroot.com .

Howdy,

Aimless and evlncrn8, you have both addressed this post correctly .
There will soon be a new 2005/2006 FAQ coming out.
The new FAQ will concentrate all RCE questions into a "UNIVERSAL FAQ"
that will better serve the entire community.

Of course we dont really expect anyone to read it .

TA TA, OBC

Ya know, sometimes RCE just appears to me as being the last barrier between "us" and "the idiots", the latter being the everyday goofs unable of understanding a principle behind an example. Some days I feel like most of the world has turned into zombies of the "press this button" droid kind. As soon as they happen to run into any unexpected variation of their daily routine, they are shaken with horror and cry for help.

P.S. Yes, the weather is disgusting and I am totally pissed off. Good thing that there are enough duds around to play lightning rod


P.P.S. If this post annoys you:
if(!IsAdmin) { get_lost;} else {delete_post;}

who says we won't read the upcoming faq? a friend of mine in my neighbourhood believes if he soaks up the old faqs he won't post to the newbie section except to answer querries since i gave him the old faqs. i like his thinking on that and will follow suit.
