今日(5/15/2023)有部份師生收到一封主旨為：「Your account is hacked. Your data is stolen. Learn how to regain access.」，如您收到此封信，請勿依照信件中的指示支付比特幣，此類的信件為勒索信件，試圖以：「駭客掌控您的設備及帳號為由進行」，並勒索要求支付比特幣，節錄內容大致如下：

Hi,

I am a hacker, and I have successfully gained access to your operating system.

I also have full access to your account.

再次提醒您，若您有收到類似郵件，請直接刪除，切勿依指示支付比特幣至指定的帳戶！
