Since the Cartoon Jihad started a number of Danish websites and blogs have been attacked and som defiled. I have seen numbers around 2000. Many death threats have been received.
I have been told by people who should know, that most of the attacks are rather primitive. Anybody willing to hack can after a few hours reading and downloads do so. But the threat is only to insufficiently protected systems. Do yourself a favor and protect your networks and servers.
There is a co-ordinated western response going on but it is hindered by the language barrier as well as the fact as there are relatively few Muslim websites. Also it is tempered by western usual reluctance to enter into conflict. Relatively few Muslims have access to the Internet and the technical expertise is generally speaking very low. This can not be a surprise, as the Muslim World has made no contribution to speak of to world civilization for the last 500 years. The worst threat is by Muslims educated and living in the west.

But Epaminondas at his blog Villagers With Torches has a brilliant solution. Check out his other posts as well. Hillarious, well written and informative.
