+ | * **Opening attachments** — Attackers may send attachments which can exploit vulnerabilities in software to harm your computer or hijack your accounts. Word documents, PDFs, and other Office documents are common vectors of exploitation. | ||

- | Naturally, if you never trusted any message or opened //any// attachment, email would not be very useful. Use your best judgement and if you feel a message is unsafe, you may want to report it as a phishing or spam email using the steps at the bottom of the message.
