Tux Machines (TM)-specific
Yes, Linux will be attacked more often in the days ahead, but far fewer attacks will get through than do on Windows.
My colleague Larry Seltzer thinks that we may be on the verge of an age of Linux worms that might rival the endless trouble that Windows users find themselves in.
First, none of the trio of vulnerabilities in the luppi worm actually have a thing to do with Linux. Yes, these worms target Linux systems, but the holes they use to target aren't Linux holes at all. They're Web service script holes.
Saying that this is a Linux problem is like saying that the gaping Macromedia Flash hole is an XP problem.
So long as you don't run a vulnerable application, your system is as secure as ever.
