What immediate action should a student take if they suspect an email is illegitimate?

Changing their password is the most appropriate immediate action to take if a student suspects an email is illegitimate. This step is crucial as it helps to secure their account from potential unauthorized access that could result from malicious emails. If the email is indeed a phishing attempt or from a scammer, responding or clicking on any links could lead to compromising their personal information. By changing their password, the student effectively safeguards their accounts from any potential threats or vulnerabilities that may arise from the suspicious email.

Discussing the email with friends may provide some reassurance, but it does not address the security risks associated with the email directly. Clicking on links to verify their authenticity could lead to malware installations or further phishing attempts, which would exacerbate the situation. Sending a reply to the sender can also be risky, as it may confirm to the sender that the email is being monitored, leading to an increased likelihood of further phishing attempts. Therefore, taking immediate action to change their password is the most proactive and secure response.
