hi,

I wanted to look more into rootkits, specially kernel mode rootkits which affect the boot sector.

Please suggest resources for me to understand and learn so that I am able to analyse these malwares.

I want to dig deep into rootkits and understand how to analyze them. I found couple of rootkit samples on this forum, need suggestions about how to begin analying them.

Any help appreciated.

Reversing rootkits is no child's play.Better start of with A..B..C instead of jumping directly to Z.

i have dealt with malware such as worms, flash based malwares with both static and dynamic analysis.
I have dealt mainly with Ollydbg which is a ring 3 debugger, for Rootkits i get that we need a Ring 0 debugger like WinDbg.

I have downloaded articles from rkhunter, I had a look at posts by rough_spear also about rootkits. I cannot send you messages as I have registered recently.
Please tell me what should i follow for more knowledge on this. I have purchased the book Rootkit Arsenal which I will be reading soon. Apart from this what should
I follow for more information on this.
