Message detective

A message announces an urgent prize. Nina slows down and looks for clues before acting.

Let's discover together

  1. 1

    Phishing tries to trick someone into revealing data or taking a dangerous action. Urgency, unexpected prizes and requests for codes deserve attention.

  2. 2

    The padlock and HTTPS indicate an encrypted connection to that site; they do not prove an offer is honest.

  3. 3

    Open the service using its official app or an address you already know. Confirm through another channel and report suspicious messages.

  4. 4

    A scam may be well written or imitate a familiar voice. Before a sensitive action, confirm through a contact you already had, without using the number or link in the message. You do not need to discover how the imitation was made to stop the request.
