The Malicious Java Applet module is not working on Windows systems.

It is not working on Windows Vista with Java 1.6.0_29 in all major browsers.

It is reportedly not working on Windows XP SP2/SP3.

It is unconfirmed whether it works on Linux/UNIX systems.

It is reportedly working fine on Mac OSX.

The module returns successfully however the shell is never received by the JavaPayload stager and the following client-side Java errors are thrown:
