Attacks or misconfigured leaks?Leaks of RFC1918 stuff is pretty common, just ask any of the root server operators how many packets they see from RFC1918 leaking networks or do a
traceroute across several residential cable network backbones.Attacks aren't as common because there is enough (not 100%) anti-spoofing (good) and/or bogon-filters (not as good) in different parts of the Internet it requires more thought to launch a spoofed DDOS than it does just to use tens of thousands of non-spoofed bots to launch a DDOS.
Arbor Networks has some data.
