I received an email in my box, claiming to be from "QuickBooks Invoice". It reads:
"Please find attached your invoices for the past months. Remit the payment by 01/07/2013 as outlines under our "Payment Terms" agreement.
Thank you for your business,
This e-mail has been sent from an automated system. PLEASE DO NOT REPLY.
The information contained in this message may be privileged, confidential and protected from disclosure. If the reader of this message is not the intended recipient, or an employee or agent responsible for delivering this message to the intended recipient, you are hereby notified that any dissemination, distribution or copying of this communication is strictly prohibited. If you have received this communication in error, please notify your representative immediately and delete this message from your computer. Thank you."
The email address looks legit, but other sites have stated it's a fabrication. It includes a .pdf file, which can be coded to include trojans/viruses/etc.
DELETE IT if you see it. It's phishing/scam/bad for you.
