I kind of got to this because of another post.. It got me thinking...

What is a R.A.T.?

I consider a RAT to be a Remote Access Trojan. The name indicates it's not "A Good Thing(tm)".
But I've also seen Remote Administration Tool. This could be anything and it suggests something benign. Like the good ol' RDP. But Netbus also get's called Remote Administration Tool. And I consider Netbus to be a Remote Access Trojan.

So what is it?
