A common tactic hackers use is to send an email with an attachment disguised as an invoice or receipt. These attachments usually have a malicious script that downloads and runs malware on your computer.
Do NOT open any attachments unless you are expecting it. If you get an email with attachment from someone you know but you weren’t expecting it, contact them to make sure they sent it.
