Emails purporting to be from the delivery company UPS or the U.S. Postal Service, claim that a package sent by you as the recipient could not be delivered. The messages instruct you to open an attachment to print out a label or an invoice. I just received two emails purporting to be from the U.S. Postal Service, saying “Unfortunately we failed to deliver your postal package you have sent on (date) because the addressee’s address is wrong. Please print out the invoice copy attached and collect the package at our office. Signed the united States Postal Service.”
WARNING: Opening the attachment will install malware on your computer. NEVER OPEN SOMETHING LIKE THIS. when in doubt, go to www.google.com and (in quotes) “type in a line of the text they sent you” so you can see who else has gotten the mail from them and what their outcome was.
