Scam Warnings.
I received an email that read:
"We were not able to deliver your postal package which was sent on the 28th of February in time because the recipient's address is incorrect.
Please print out the invoice copy attached and collect the package at our department.
DHL Services."
The attached file is a ZIP format file which actually contains a nasty piece of code that will log the sites you visit and also the usermnames and passwords given for those sites. It then reports back with that information to whoever sent the code out in the first place (not the person named as the sender of the email). To make matters worse, it does all this stealthily, changing security settings in Internet Explorer so that it's not detected.
If you receive such an email, delete it.
I was alerted to this due to the fact that I have never sent anything via DHL.
While I may, personally, have issues with DHL's service I can confirm that DHL have no connection with this email, their name is being used to try to add authenticity and get you to open the "invoice".
