Re: 'rooted' NT/2K boxen?

["Cody Hatch" <cody () halosec com>]

Yeah, sorry, I meant Task Manager. I unfortunately I don't have a copy
of lb.exe, although it was impressive. It did a great job of hiding all
of the processes from all monitoring agents. The only reason the person
knew they had it was they had Snort running. It caught and logged the
Unicode attack. They were running IIS 5.0 on a Win2000 machine, too.
Netstat didn't show the open port connecting to the IRC channel, and
neither did fport. There was even a GUI menu that showed which processes
were hidden and which one's weren't. You could choose which things to
hide, and which ones to let show. All of the normal methods of gathering
system info were on the menu. I didn't get to make a complete forensic
examination because the user of the box had messed around with things
before I got there.
