Virtually every base of data transmitted on the internet is vulnerable and obtainable. VISA, Paypal, Banks, Xbox, Sony, just about every company has there data stored somewhere. And about %90 of the time it's foreign Indian people running there security and have no idea what in the fuck there are doing. That's aside from Snapchat, which is just another example. I guarantee the person reading this has an old email with I.P address stored in a leak with the password, PM me and i can help you get it removed if you haven't already. Playstation's entire customer database was also leaked recently as well as anyone buying anything from target has had there CC's compromised and are also out on the internet.
