An employee receives an urgent email that appears to be from their CEO, requesting the immediate transfer of sensitive customer data to an external consultant. The email has a slightly unusual tone and sender address. What is the most appropriate first action for the employee to take?
-
A
Immediately send the data as requested to be efficient.
-
B
Reply to the email asking for more details about the consultant.
-
C
Do not reply; instead, use a separate, known communication channel (like a phone call) to verify the request with the CEO and report the email to the IT/Security department.
-
D
Delete the email and ignore the request, assuming it's spam.
