What is Intercage? In short, a (hopefully) former host of thousands of sites purveying malware. But since I ran out of time this evening and only got as far as collecting some of the sources so will post a link to the news via Alex at Sunbelt Blog. See Dancing in the streets (almost): Intercage going down in flames and The Atrivo/Intercage saga continues. From Alex' posts, be sure to follow the links to Brian Krebs reports.
Also see the update posted at Hosts News.
