The "infected" machines/vm's were probably behind on software updates. Linux still has that fatal flaw called the user, if the user doesn't update when a bug is found and patched, then the system stays vulnerable.
In all, what probably happened was a service on the servers was vulnerable in some way, the attacker rooted the box, and then installed nginx(which is not a virus, it's a legit web server) on a non-standard port, and Bob's your uncle, you got a place to serve whatever ya want. Just my 2 cents. On Mon, Sep 14, 2009 at 12:01 AM, Loren Faeth <lfa...@leadingchange.com> wrote: > > > > > > Uh, Wonko, what was that about no virus on linux.
