Ran across this "exploit kit" today. I'm holding up my hands with air quotes:
Not really sure if it is an exploit kit, as so far, it is just a landing page with applet redirection to a jar file.
The GoogleDocs.jar file that is mentioned above is a simple generated jar exploit straight out of Metasploit with no obfuscation.
ClamAV already detects this with
Java.Trojan.Agent-31. Just a Java archive with an embedded executable.
