What is a phishing attack?

A phishing attack is a fraudulent attempt to obtain sensitive information, particularly personal data like usernames, passwords, credit card numbers, and other confidential details. This is typically done by masquerading as a trustworthy entity in electronic communications, such as emails, text messages, or websites that appear legitimate.

Phishing relies on social engineering tactics to trick individuals into divulging this information. For instance, a user might receive an email that looks like it is from a reputable bank, requesting them to click on a link and enter their login credentials on a fake website designed to harvest that information. Understanding this concept is crucial in recognizing the importance of safeguarding personal data online, as well as knowing how to identify potential phishing attempts.

The other options do not accurately describe phishing attacks. For example, disrupting network services relates more to denial-of-service attacks, encrypting data pertains to data protection techniques, and securing internet connections usually involves protocols and measures rather than deceptive practices.
