Browser Autofill Phishing
This is a simple demonstration of form fields hidden from the user, but will be filled anyways when using the browser form autofill feature, which poses a security risk for users, unaware of giving their information to the website.
Google Chrome behaviour
Here's the demo in action on the Google Chrome Browser:
It works differently in some other browsers. For example:
In Safari, it will tell you all the data it is filling into the form, even if it isn't visible to you.
In Firefox, you have to right click an input field and then select an identity to use. So a Firefox user autofills each field.
