U CAN HAZ METASPLOIT TOO. ENJOI.

(svn update will pull the current code in... it's under intense revisioning right now; something like 6 revisions in 5 hours this morning)

The current version will actually replace the cached entries for the name server itself, allowing you to hijack entire domains at once. Previous code (form earlier this morning) would allow you to take over individual entries (e.g. randomwhatever.example.com), but now you can take over (*.example.com).

Patch up, children.
