SubjectRe: Kernel Rootkits
hi,

I got the terminology mixed up. I guess what I really want to know is,
what are the different types of exploits by which rootkits
(specifically the ones that modify the kernel) can get installed on
your system.(other than buffer overflow and somebody stealing the root
password)

I know that SucKIT is a rootkit that gets loaded as a kernel module
and adds new system calls. Some other rootkits change machine
instructions in several kernel functions.

Once these are loaded into the kernel, is there no way the kernel
functions can be protected ?

thanks,
Allison
