It looks like a vulnerability in the AWStats tool that runs on Apache is causing some troubles for people who aren't patched to the latest version. I woundn't mention it normally as this runs on Linux, but I've seen at least one person who's blog server was attacked and I want to make sure that people running Apache servers patch themselves against this. (There's a warning you should read on the AWStats site.) I've seen a couple of bizarre redirects the last couple of days and I suspect this might have something to do with it. Here's a link to some Sans coverage of this exploit.
