The LA Times reports that the same family of virus/malware/badware that inf=
ected Target a couple of years ago is making the rounds again this year, ta=
rgeting retailers.  The interesting thing to me was that the badware uses e=
ncryption to change its signature.

My question is whether any 'common' badware such as detectable by today's c=
ommercial engines have this capability.  Names would be nice or just an ack=
nowledgement that such badware exists.  I'm curious as to how the commercia=
l anti-virus companies even detect this type of badware, maybe they know of=
 a initial signature that's always present before the badware morphs, and t=
hey detect this signature?
