CERT, just released their "Windows Intruder Detection Checklist" from the article :
"This document outlines suggested steps for determining whether your Windows system has been compromised. System administrators can use this information to look for several types of break-ins. We also encourage you to review all sections of this document and modify your systems to address potential weaknesses."
I find it a well summarized checklist, perhaps the first thing that I looked up when going through it was the rootkits section given the topic. It does provide links to free tools, but I feel they could have extended to topic a little bit. Overall, consider going through it. Another checklist I recently came across is the "11 things to do after a hack" and another quick summary on "10 threats you probably didn't make plans for".
Rootkits are gaining popularity, and with a reason -- it takes more efforts to infect new victims instead of keeping the current ones, at least from the way I see it. In one of my previous post "Personal Data Security Breaches - 2000/2005" I mentioned about a rootkit placed on a server at the University of Connecticut on October 26, 2003, but wasn't detected until July 20, 2005, enough for auditing, detecting attackers and forensics? Well, not exactly, still something else worth mentioning is the interaction between auditing, rootkits and forensics. There's also been another reported event of using rootkit technologies for DRM(Digital Right Management) purposes, not on CDs, but DVDs this time, so it's not enough that malware authors are utilizing the rootkit concept, but flawed approaches from companies where we purchase our CDs and DVDs from, are resulting in more threats to deal with!
