The Department of Homeland Security's US-CERT has stated that the software that comes with the Energizer DUO USB battery charger contains a trojan.

"The Energizer DUO, a USB-powered nickel-metal hydride battery recharger, has been discontinued, said Energizer Holdings, which late Friday confirmed that the software contains malicious code," writes Computerworld's Gregg Keizer. "The company has not said how the trojan made its way into the software, however."

"The Windows software included with the charger is designed to show battery-charging status," Keizer writes. "When the software is installed, it creates the file 'Arucer.dll,' which is actually a Trojan that listens for commands on TCP port 7777. Upon instructions, the Trojan can download and execute files, transmit files stolen from the PC, or tweak the Windows registry."
