researcher, I'm wondering what an intruder could do if they did get into your brokerage account. They may be able to buy or sell a stock in your account, and that could screw you up, but I doubt that they would be able to get any money out of it. If they requested cash, it would be sent to your house. If they tried to get cash sent somewhere else, I'm sure that would raise red flags at your brokerage house and they would call you to verify. What am I missing?
