I saw a new scam today that I'd never seen before and it was pretty well crafted. They spoofed the sender address to make it look like it came from a reputable company. The message indicated that DHL had tried to deliver a package but had the wrong address. Their e-mail had an attachment that was supposed to be a password protected PDF file and their message indicated the PDF file had the shipping label that needed to be corrected and returned. It went on to say that if DHL was unable to deliver the package I'd be charged a daily "storage" fee of $9.12. The file attachment did contain a bogus DHL shipping label to some Middle East company along with a script and VBS basic program to execute their little virus.
If you run a Windows system this is one you need to watch out for.
