Browse while knowing where you are

A message promises to take Lumi to the Rullst Academy. The title looks right, but the address deserves a second look. Learning to locate the domain helps you ask better questions.

Let's discover together

  1. 1

    A browser is the tool; a search helps find pages; a website is a destination. Typing words into the bar may run a search. Typing a known address can open that address directly.

  2. 2

    In https://academy.rullst.win/pt-BR, the host name is academy.rullst.win and /pt-BR is the path. A title, picture or familiar word elsewhere in an address does not prove you are on that host.

  3. 3

    The example academy.rullst.win.exemplo.invalid is fictional: it ends in exemplo.invalid and is not the Rullst Academy address. Do not open exercise links; compare the text. HTTPS protects the connection but does not make every page honest.

  4. 4

    If an unexpected page asks for your password, pause. Return using the known address or a bookmark you checked. On a shared device, sign out when finished; signing out differs from merely closing a tab.

YOUR MISSION

Separate browser, search and website; identify the known address before signing in.

Now it's your turn

Discovery workshop

Read before signing in

Compare only the text. No fictional link needs to be opened.
Build your answers and check when you are ready.
A moment to understand

A page has HTTPS and Rullst Academy in its title. Is that enough to trust it?

I need a hint

A protected connection is not a judgment of the page’s honesty.

Loading your journey…

Take it with you

On paper, mark the host and path of an invented address ending in .invalid. Then explain why a familiar word inside an address is not enough assurance.

Show me the Rust behind it

This part is optional. You don't need to memorize the code to continue.
