UPS malware now sent via DHL!
For the 3rd day running we are seeing vast quantities of email-attached malware. Today the spoofed sender was DHL with subjects like “DHL Express Service”. The emails included standard test such as:
Dear customer.
The parcel was sent your home address.
And it will arrive within 3 business day.
More information and the tracking number are attached in document below.
Thank you.

In their desperation to push out more malware today the senders seem to have overlooked the required filename change – the “DHL.zip” files are now carrying …… UPS.exe (as distributed in the last 2 days).
There is a clear push to build a large number of infected computers – maybe an attempted botnet rebuild following the demise of Rustock in mid-March? The graph below shows the malware portions of daily email (orange line), with large daily outbreaks clearly visible.
