Which common warning signs indicate an email may contain a malicious attachment? Select all that apply. The attachment is unexpected. \( \square \) The sender's address looks slightly different. \( \square \) The email is unexpected.

One of the most telling signs that an email might harbor a malicious attachment is if the email’s content feels off or is comically disjointed. If the tone seems overly urgent, or if it refers to things you never discussed (like choosing your free vacation package!), that’s a solid indicator you should proceed with caution. Always trust your instincts! Another red flag is the sender's address. If it appears to come from a familiar company or individual but has a slight misspelling or uses a different domain (like "example.com" instead of "example.org"), it can be a clever impersonation tactic by cybercriminals. Stay vigilant and verify!
