This is a new one on me. Apparently, Energizer is responsible for exposing customers who bought a simple USB battery charger to a Trojan.

Confused?

Apparently, the charger allows you to view the battery charging status on a computer if you installed a piece of software. Unfortunately for Energizer, the Windows version of the software had a vulnerability in it that allows unauthorised remote system access.

The flaw has been highlighted by the US Computer Emergency Readiness Team (US-CERT), who advised users to uninstall the software.

Red faces for Energizer, which has discontinued the charger and says it is investigating how the code got into the software. Its statement on the matter is here.
