Here is a great video I found. It's from LiveSecurity's Malware Analysis series. This video talks about rootkits, what they do, and how to protect your server from someone using one. This video shows how the rootkit looks from both the hackers view and the victims! This is a must view for anyone interested in protecting their server and users from hackers and malware. This is part one of three, be sure to check the other two out as well. They can be found for free on Google Videos
