Watch out for the coordinated attack
Landing on the following site not only get you a Codec/Zlob prompt, but my AV (NOD32 v3) jumps up and announces there is also an IFrame attack (JS/TrojanDownloader.Psyme.AAW) from several sites ...

Although unusual for several exploits to be on the same (Codec) site ... it's nothing new ... as you can see below you get redirected several times and are attacked from several sources ... thankfully several are already blocked (entries in red) by the HOSTS file, and NOD32 killed the connection (zero bytes) to the site displayed above ...

As you can see below there is quite a cast of characters involved ... although these sites are hosted on several different IP blocks ... they are all related ... the download is actually from "thehotcodeczz(dot)com" which was only registered 18-Mar-2008

So what happened to my machine? ... absolutely nothing! Just goes to show you that the majority of these type attacks can not get past the defenses of Windows Vista SP1 ...
