# Try a free ethical hacking lesson

See how a website gets information from your browser, then use what you learned to find a bug in a pretend pizza shop. It's free, takes about 15 minutes, and there's nothing to sign up for.

## How a website hears you

Reading1 min

Every time you open a page, press a button or fill in a form, your browser sends the website a short message. The website reads it and sends a page back.

Your browser

The website

That message is where a lot of website bugs live. If a website believes something in it that it shouldn't, that's a bug, and finding those is what ethical hackers do.

In this lesson you'll try the two most common ways your browser sends a message. Then you'll use what you learned to find a bug in a pretend pizza shop. You don't need to know any code.
