A user deletes a suspicious email from an unknown address.

The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) defines phishing as:

“Creating a site or sending an email that masquerades as a legitimate secure site but actually steals your information is called phishing.”

It further explains:

“When people talk about phishing, it’s generally in the context of suspicious email because that’s how the term originated. Hackers sent out messages hoping to get someone to take the bait.”

By deleting a suspicious email without opening or clicking links, the user is practicing anti-phishing awareness — a key cybersecurity best practice.
