It's about the same as old telemarketing scams; If you can provide small snippets of information, just to make the target "buy in" to the scam and make it legit, a lot of people will fall for it. I should know, i work for a customer service/telemarketing firm. It would be very easy to just provide small pieces of info, to sound like you really have all of their information, and they give you anything you want, hook line and sinker. I've got fraud emails from different banks, etc....But a lot of them I have never heard of, or am a customer. same with ebay. This is just a new form of scams. Just like the ebay email for instance; send a million emails, that look legit, with a link that actually looks like an ebay link, how many people will you reach that probably has an ebay login? same with the banks. A lot of people don't pay attention, see the logo, and panic about their account. They hoooked onto the "buy in" and fell for it. Create the interest in buy in, with a scare, and you can go wild. Not only that, with someone's ebay login, it's a good possibility that you can access paypal too; many people will use the same login for both, instant access to accounts. People really need to be made aware of these things by companies, if they value their consumer base.
