From the doc: 'This is a sacapass of MSN Messenger; it is not guaranteed that everytime you use it you'll obtain the password of the victim as this program is based a little on social engineering. You send the *exe to the victim; when the victim opens it, it'll close victim's session in MSN and at their pc will appear a window of false reinforcement session; if the victim introduces his/her password in this false reinforcement session, his/her password will be yours'
