Tracking cookies, or just cookie grabbing in general.
Cookies are information that is saved when you view a website, fill out a form, ect.
Some hackers use “cookie-grabbers” and steal that information and dissect it to get pretty much any information they want about you.

Scary, huh?

I recommend setting your browser to delete cookies everytime you close the browser.
