Crack!

Post by totte1015 on Fri 27 Jul 2012, 08:50

First of, this is NOT any kind of request for crack, just me wondering.

How long time does it take to come up with a crack for a PC game?
I always wondered how the process goes, what program you use to crack it...
Is it based on textfiles and very advanced language and such?

Hello,

I've actually looked into it at some point and it's not quick or easy. It boils down to this:

The main steps of cracking:


There are 7 steps in the process of cracking:
1. Run the program you want to crack and learn it's standard behavior.
Try to locate strings and keywords, try to enter the password and see how the program responds.


2. Open up the program with the W32Dasm and disassemble it.


3. Find typical and common strings in the disassembly that appeared in the program. In most cases, you have to look for keywords such as: password, name, date, expired, time limit, wrong, entered and so on.


4. Find and observe the password generator, find the learn protection routine and the API calls.


5. Try to understand the jumping mechanism of the protection.


6. Open up the program in HIEW. Change the jump of the flow control to it's opposite jump command, or nop it out.

7. Run and see how the change you have made in the original program affected it. Feel the power you have, the power of cracking, letting programs behave as you want them to.

Learn those steps very well, until u dream of them, u will use them in every program you crack.

Hello,

If you know what you're doing, you should be able to do it in less than an hour.

Hello,

Sure, but it takes time to learn these things. I simply could not concentrate on the tutorial with 2 kids around asking me questions every 2 minutes Laughing

Hello,

But The Sims 3 is a whole new level, though.

Now i was more thinking of Prototype 2, since it was released today.

That about it takes less than a hour is just for the sims 3, i guess?

Hello,

I think The Sims 3 is more complicated than most to be honest.
You're welcome to have a look at the link I posted and give it a try Very Happy and we'd be happy to hear about the results.
