First, I think that forwarding messages from a private list is something that is frowned upon. Secondly -- and speaking as a Trend employee and someone intimately involved in the ICSS/BASE project -- we don't talk/play in the BGP traffic stream. We simply reap potential target data from a BGP/Origina-AS/perfix-announce dataset, and then allow the ICSS/BASE subscribers to make polict decisions on their merit -- whether to allow their downstream hosts to reselve DNS queries to suspect hosts, or not. We do not, in any way, piss into the BGP traffic stream. :-) It's just an intelligence feed -- one of many. - ferg -- brett watson <brett@the-watsons.org> wrote: On Sep 25, 2006, at 9:04 PM, Jeff Kell wrote:

Well, a prefix hijack either means a router has been pwned, as I suggested, or a router is (as Governor Tarkin put it) "far too trusting" of its peers.

And anyhow, I was speaking of BGP flaps in the context of botnets - has anybody seen an in-the-wild botnet that played BGP games?

No, but playing some BGP games could certainly help to *mitigate* them. Turn the C&C list into a community. I've thrown the idea around several times but can't get any takers...
