A customer of a large company receives a phone call from someone claiming to work for the company and asking for the customer’s credit card information. The customer sees the caller ID is the same as the company's main phone number. Which of the following attacks is the customer most likely a target of?

Vishing is the correct answer because it describes a social engineering attack conducted over the phone, where the attacker attempts to trick the victim into revealing sensitive information. The scenario explicitly mentions a phone call and the request for credit card information. The use of caller ID spoofing to display the company's legitimate phone number is a common tactic in vishing attacks to build trust and deceive the victim. Phishing is incorrect because it refers to attacks conducted via email. Whaling is incorrect because it is a type of phishing attack specifically targeting high-profile individuals within an organization. Smishing is incorrect because it refers to phishing attacks conducted via SMS (text messages).
