Hmmm. A new vector for malware: USB battery chargers. Wonderful.

The U.S. Computer Emergency Response Team (CERT) is warning that Energizer DUO USB battery chargers have been found infected with a Trojan that loads backdoor malware on a victim PC along with its battery monitoring software.

The charger copies a .dll file named UsbCharger.dll in the application’s directory and another named Arucer.dll in the Windows system32 directory. USBCharger sets a registry entry to autoexecute Arucer.dll when Windows starts.

Arucer.dll is a backdoor that communicates through TCP port 7777.

The charger has been sold worldwide for three years.

CERT notes that the Trojan contains Chinese language text.

Sunbelt detects it as Trojan.Arugizer.
