This is a module from the Browser Exploitation Framework (BeEF) to load a malicious Java Applet on the client. If the client runs the applet a connection from the client’s system to the attacker’s system is made using the Metasploit Exploitation Framework. This was demonstrated during “Unmasking You!” at BlackHat 09 and DEFCON 17 by Joshua “Jabra” Abraham and Robert “RSnake” Hansen.
