That paper is about reflection attacks.  From what I've read, this was 
not a reflection attack.  The IoT devices are infected with botware 
which sends attack traffic directly.  Address spoofing is not particularly 
useful for controlling botnets.  

But that's not only remaining use of source address spoofing in direct 
attacks, no?  Even if reflection and amplification are not used, spoofing 
can still be used for obfuscation.

I agree that it would be nice if more networks did ingress filtering,
but if you're expecting a major decrease in evil, you will be
disappointed.

At this point it's mostly useful for identifying the guilty or
negligent parties afterwards.

R's,
John
