There are various types of malicious emails that internet users should be aware of:

E-mail di phishing

Phishing emails are commonly used by cybercriminals to trick users into giving away their sensitive private information, come le informazioni di accesso per vari servizi online, account email, o informazioni bancarie online. Cybercriminals often use popular service logos (per esempio., Microsoft, DHL, Amazon, Netflix) and create a sense of urgency to trick users into clicking on a link. The link then redirects victims to a fake website, where they are asked to enter their password, dettagli della carta di credito, or other information.
