Ah, the computers in MLL... primitive.
They use analog modem dial-up... a very primitive technology very prone to hacking. You just need to download a dialer, run it, then it will replace all existing TCP/IP settings. Then the call can be routed to another fake ISP and all computer activities can be recorded, including MLL guest's email password, CC#, etc.
There are lots of dialers like this available.. some will make your modem dial international 011# to generate telecom income... They can be found mostly on, hmm, you know where
