Another stealth attack type is browser cookie theft. It is said that browser cookies make the web run. Simply put, cookies preserve the action ‘state’ of the user as you surf through the internet. These little pieces of text are sent to our web browser from the websites we frequent making it easier to login, purchase items and generally pick up where we left off.
