Your CFO receives an email with her name that claims to be the company's bank and tells her to click the link https://chase.bankofamerica.mysite.ru. Which type of attack is this?

Spamming involves sending mass, untargeted emails, unlike this highly personalized attack.

Phishing is a general term for deceptive emails, but this attack's specific target (CFO) and high-level impersonation make it more precise than general phishing.

Spear phishing is targeted, but whaling is a more specific term for attacks targeting C-level executives or other high-value individuals, making it the most accurate classification here due to the target's role.

Whaling is a specific type of spear phishing attack that targets high-profile individuals, such as executives (like a CFO), because they often have access to highly sensitive information or financial assets. The email's personalization, impersonation of a trusted entity (the company's bank), and attempt to trick her into clicking a malicious link are all hallmarks of a whaling attack.
