Software that can be downloaded for use with the Energizer Duo USB 
battery charger contains a backdoor that could allow an attacker to 
remotely take control of a Windows-based PC, Energizer and US-CERT is 

"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," the U.S. Computer Emergency Readiness Team 
said in an advisory on Friday. "Arucer.dll is a backdoor that allows 
unauthorized remote system access via accepting connections on 7777/tcp. 
Its capabilities include the ability to list directories, send and 
receive files, and execute programs."

The Windows software was made available via a download with the 
Energizer Duo Charger, Model CHUSB, Energizer said in a statement.

The battery maker said it does not know how the Trojan got into the 
software. "Energizer has discontinued sale of this product and has 
removed the site to download the software," the statement said. 
"Energizer is currently working with both CERT and U.S. government 
officials to understand how the code was inserted in the software."
