There is an excellent discussion of the Blue Security DDOS attack here, including a copy of discussion from those behind the DDOS here. There is more information on Blue Frog and related issues on Wikipedia here. If you somehow missed this, it is probably in your best interest to be aware of what is going on here. A lot of people have been affected, and this isn’t over yet.

[Update: 5/17/06: Wired reports in this article that Blue Security has shut down their Blue Frog service in response to the attacks; however, talk of alternatives are starting up here, here, here, and here. ]

[Update: 5/21/06: There is a wiki on Okopipi here, and an interesting blog entry here.]

In the meantime, grab a Network Monitoring software from here and manage your Syslog servers from here.
