Today, we received a notification about a new Linux malware ItW (In the Wild).
Chas Tomlin (http://www.ecs.soton.ac.uk/~cet/) provided Shadowserver (http://www.shadowserver.org/) and Nicholas Alright who notified the relevant operational communities, with the information on the binaries. He captured them with squil (http://sguil.sourceforge.net/).
Chas is working with Shadowserver to identify better ways to trackdown/takedown botnets.
*The credit should go to him and Shadowserver*.Shadowserver has been a responsible and essential part of recent Internet security activities.
As anti virus vendors have been notified will soon do a write-up on it, I see no reason not to publicize it here.

We hope to know more soon and we will update as we do.
