Linux webserver botnet pushes malware
A security researcher has discovered a cluster of infected Linux servers that have been corralled into a special ops botnet of sorts and used to distribute malware to unwitting people browsing the web.
Each of the infected machines examined so far is a dedicated or virtual dedicated server running a legitimate website, Denis Sinegubko, an independent researcher based in Magnitogorsk, Russia, told The Register. But in addition to running an Apache webserver to dish up benign content, they've also been hacked to run a second webserver known as nginx, which serves malware.
"What we see here is a long awaited botnet of zombie web servers! A group of interconnected infected web servers with [a] common control center involved in malware distribution," Sinegubko wrote here. "To make things more complex, this botnet of web servers is connected with the botnet of infected home computer(s)."
