What does this botnet do when it's not performing a 7.3 Tbps DDoS? Yea it's probably regular folks computers, but what "wakes up" the botnet to attack? What makes an attack target worthwhile? Presumably something this large would be on someone's radar...

I mean... 7 Tbps sounds like a lot, but 1Gbps symetric connections are common in many areas. 7,000 botnet nodes with good connectivity can deliver that. The article says the attack traffic came from 122,145 source IPs, but I would expect at least some traffic to be spoofed.
