If you use Dropbox you may have gotten an email asking you to click on a payment invoice. DON’T CLICK ON THE LINKS!!
This is a phishing scam. The sender is hoping you will click on the links they can either infect your computer with malware or that you will provide credit card or other payment information to pay the invoice.
The email I received came from this email address: firstname.lastname@example.org, which is not a Dropbox email. Casey Smith is referenced as having shared a document and requesting payment on the invoice. It was sent to an email address I only use to receive inquiries, I never send outgoing mail using it and no one I might get an invoice from would have.
Again, do not click on any links if you get this email.
I make it a regular practice to look at the email address of the sender, that usually tells me all I need to know, that it is not an official email.
Please share this with anyone who uses Dropbox.
