A college student receives the email shown in the exhibit.

This is a classic phishing lure (“Validate Email Account”) where the attacker aims to create trust by presenting a familiar-looking sender identity to the recipient. In many real phishing waves, attackers manipulate what the user visually trusts first: the friendly name (display name) shown by mail clients. “Display Name Spoofing” is specifically when the attacker sets the From display name to something authoritative (e.g., “HelpDesk”, “IT Support”, “University Admin”) while the underlying sender address may not be an approved helpdesk identity, or may be a compromised mailbox that is not actually the IT department. Proofpoint IR review commonly verifies this by comparing: (1) the displayed name, (2) the RFC5322.From address, and (3) authentication results (SPF/DKIM/DMARC) plus “Header From vs Envelope From” alignment. Lookalike domain focuses on deceptive domains (e.g., great-c0mpany.com) rather than the visible name; Reply-To spoofing requires a mismatched Reply-To field, which is not the primary indicator shown in the exhibit. For response, analysts prioritize user notification, link detonation/URL Defense verdicts, and retroactive search-and-pull (TRAP/CTR) if delivered.
