Which phishing attack method is characterized by the use of SMS text messages?

The method characterized by the use of SMS text messages is known as Smishing. Smishing is a form of phishing that targets individuals through text messages (SMS) rather than email. The term is a combination of "SMS" and "phishing," highlighting the specific channel through which these scams operate.

In a smishing attack, an attacker sends a seemingly legitimate text message that often includes a link or prompts the recipient to call a number, convincing them to provide personal information or download malicious software. This method is effective because many users may be less cautious when dealing with text messages, assuming they come from trusted sources.

Understanding the different categories of phishing is vital. Whaling, for instance, specifically targets high-profile individuals within an organization, like executives, and typically utilizes email rather than SMS. Vishing employs voice calls to trick victims, utilizing phone calls instead of text messages. Traditional phishing refers to scams that are primarily conducted through email. Each method is distinct in its approach and the medium used, but smishing specifically highlights attacks conducted via text messages, making it the correct answer in this context.
