This was sitting in my drafts folder for quite some time. It seems that ITU has (had?) and effort to create a botnet mitigation toolkit. As the web page says:
The first draft of the background material for the project was made available in December 2007 with pilot tests planned in a number of ITU Member States in 2008 and 2009.
It is 2010 now, so does anyone have any more information on the toolkit’s progress?
