Malware Alert!

Sunbelt/GFI Labs have reported seeing an increase in a new wave of  “PDF malware” which poses as a message from the United States Postal Service (USPS) and bears the subject “Package  was not able to be delivered please print out the attached label”.  The message body reads as follows:

Hello!

Unfortunately we failed to deliver the postal package you have sent because the recipient’s address is erroneous.

Please print out the shipment label attached and collect the package at our office.

United States Postal Service

Here is what the attached file looks like once downloaded onto a system:

When in doubt, double check with the supposed sender by calling their office for confirmation, but do not reply to the sender’s email address. With Black Friday and Cyber Monday  just around the corner , and the increase in online  shopping,  it can be  expected that  such attacks will multiply in the coming weeks.
