Security researchers have discovered what appears to be an experimental Linux rootkit designed to infect its highly select victims during a classic drive-by website attack. The malware allows hackers to inject code directly in any infected web page. The new malware, discovered on November 13 of this year, was written especially for servers that run Debian Squeeze and NGINX, on 64 bits.

Interesting. The problem is that this only works on 64 Bit versions of Squeeze and run the Linux Kernel 2.6.32-5-amd64. I don't see this working as long as hired administrators are doing their jobs and keeping the server updated. The amount of impacted servers should be very minimal (I hope that is).
