Auswertung

Dein Opa bedankt sich bei dir und bearbeitet die markierten Mails. Doch nach einigen Tagen passiert etwas Seltsames. Es stellt sich raus, dass du mindestens eine Nachricht markiert hast, obwohl sie nicht echt war. Dein Opa und du seid auf (einen) Täuschungsversuch(e) reingefallen, wodurch Kriminelle nun seine Zugangsdaten haben.

Aber alles gut! Das war nur ein Test. Aber du hast gesehen, wie schnell es passieren kann.

Auswertung

Dein Opa bedankt sich bei dir. Und noch besser: einige Tage später schaut sich deine Mama nochmal das Postfach an und sieht, dass unter den gelöschten Mails Täuschungsversuche waren. Hätte dein Opa diese beantwortet, hätten Kriminelle seine Zugangsdaten erhalten können.

Doch du hast alles erfolgreich erkannt und gelöscht. Sehr gut!
