An employee receiving a gift card request in an email that has an executive's name in the display field to the email describes a possible business email compromise attack. Business email compromise (BEC) is a type of phishing attack that targets employees who have access to financial or sensitive information, such as accounting, human resources, or executive staff. The attacker impersonates a trusted person, such as a manager, vendor, or client, and requests a fraudulent payment, wire transfer, gift card purchase, or personal information. The attacker may spoof the email address or display name, use a look-alike domain, or compromise a legitimate email account to make the request seem authentic.
