I hear tell that some folk are engaging in this practice... You might have seen this hear little ditty: <http://tools.ietf.org/html/draft-byrne-opsec-udp-advisory-00> you may have also put your ear to the tracks and seen a bunch of kids using these 'you-dee-pee en-tee-pee' packets to fill up the tubes across the lands... Sometimes they use not just 'en-tee-pee', but also that old hoary bastard 'dee-en-ess' for their no good traffic backup propositions.
there a reason why this is often done so? Is this because UDP is stateless and any script kiddie could launch a DOS attack with a UDP stream?
I understand, and I'm new hear so bear with me, that there are you-dee-pee services out there in the hinterlands which will say a whole lot more to you than you said to them... like your worst nightmare when it comes to smalltalk.
Given the state of affairs these days how difficult is it going to be for somebody to launch a DOS attack with some other protocol?
not very hard at all... but here's your lipstick and there's the pig... :)
