I think thier goal is to first gain access to your E-mial account, then work thier way up the ladder from there. Maybe gain access to your personal banking info (passwords) saved on your computer, as a lot of people bank soley on the PC now. It is possible that some fool will even hand them the golden ticket, the info to access thier bank account without the fight.
These jack holes got nothing better to do then scam people out of thier money.
