Waledac botnet goes down

Another triumph in the "yes, you can fight spam" category: Kaspersky lab's Thread Post newsletter is reporting that the Waledac botnet has been knocked nearly completely off line and is sending almost zero spam.

I briefly mentioned the Waledac botnet in an earlier post in which I reported that Microsoft had significantly damaged the botnet's command-and-control servers via court order.

More details can be found on Microsoft's security blog in the article What we know (and learned) from the Waledac takedown.
