Excellent articles on malicious webservers

Due to me not having posted in quite some time, I haven't mentioned this before, but back in August the Honeynet Project posted an excellent article about their findings related to searching for malicious webpages. Well, now they have released a followup article which deals specifically with the software used at some of these sites, which gives attackers rather advanced capability with very little difficulty. These are important reads to fully understand and appreciate the state of the art in browser-attacks.
