Step-by-step explanation:
The security threat that uses email to trick users is Phishing.
Phishing is a type of cyber attack where attackers impersonate legitimate organizations and send emails that appear to be from trusted sources. These emails often contain malicious links or attachments that, when clicked on, can lead to the theft of sensitive information such as passwords or credit card details.
