Miles has initiated a scam in which he counterfeits a well-known banking website and sends out e-mails to direct victims to it. By making this website look authentic, he is able to get victims to reveal their social security numbers, bank account numbers, and credit card numbers. What type of scam is Miles running in this scenario?

Answer: Phishing

Explanation: Phishing is a cybercrime or scam whereby targets are made to reveal their personal information like login details, credit card numbers and other confidential things by sometimes sending them emails that are supposedly from their service providers like their banks, requesting for these things to enable them make some "corrections" in their accounts, whereas the information obtained is just to steal or defraud them of their money and valuables.

Phishing is a type of social engineering attack often used to steal user data, including login credentials and credit card numbers. Like i earlier states, it occurs when an attacker, masquerading as a trusted entity, dupes a victim into opening an email, instant message, or text message just for the purpose of scamming them and defrauding them. This is exactly what Miles from the question is doing.
