Windows USB Battery Charger that Tunnels through a Firewall?

This is not a joke. This was posted on the US-CERT site. US-CERT is the operational arm of the National Cyber Security Division (NCSD) at the Department of Homeland Security (DHS). It is a public-private partnership.

"Energizer DUO is a USB battery charger. An optional Windows application that allows the user to view the battery charging status has been available on the Energizer website. The installer for the Energizer DUO software places the file UsbCharger.dll in the application's directory and Arucer.dll in the Windows system32 directory. When the Energizer UsbCharger software executes, it utilizes the UsbCharger.dll component for providing USB communication capabilities. UsbCharger.dll executes Arucer.dll via the Windows rundll32.exe mechanism, and it also configures Arucer.dll to execute automatically when Windows starts by creating an entry in the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run registry key."
