It seems that Dan Kaminsky will be doing a presentation at an upcoming Blackhat meeting.

An article on this is found at SANS.Org -
[isc.sans.org...]
"an upgrade or patch of all recursive DNS servers is what's really needed at this point."

The message, if you have not done so already, you will want to make sure any and all recursive DNS servers under your control have been patched to avoid a problem with cache poisoning.

An earlier thread here at WebMasterWorld from July 8th offers awareness information about the problem and some other resources you can check out -

"Where can I find details of this exploit?
Details of this new vulnerability have not been released yet to allow for administrators to patch their servers before the technique becomes well known to attackers. However, an exploit has now been released into the wild."
