JustKernel

Windows Kernel is not about writing device driver . Its a lot more than that. So if you are passionate about Kernel and want to find out answers to some basic questions like :

• How a program gets executed ? What is its organization in memory (RAM).
• What is boot sector?  What is its role ?
• What are ISRs ? When an interrupt occurs how ISR services the request.

and similarly some others..

To find out solution to these questions, what we generally do is to read some books or search on net and most of the times we get our answers .

We are satisfied and that’s an end to it.

But no.. Practicality / Practical usefulness is what we need to understand. That’s what at-least I think so.

So here I will present you with the practicality of these theoretical concepts. I will try to explain the role of these components in OS. But in somewhat different way.

I will try try to explain these concepts with the help of some small viruses / hacks and hooks in Windows Kernel..

Please don’t get me wrong. My aim is only to explain the concepts not to harm anyone. So I would request you to please try the samples in your lab environment which should not cause harm to anyone else.

I would again like to stress, my intention is just to spread knowledge which is everyone’s right.. There is no negative side/intention towards this exercise.
