Computrace back door could make millions of PCs vulnerable

Almost all recent PCs have Absolute Computrace embedded in their BIOS. It's a product designed to allow companies to track and secure all of their PCs from a single cloud-based console.

But researchers at Kaspersky lab have revealed that it often runs without user-consent, persistently activates itself at system boot, and can be exploited to perform various attacks and to take complete control of an affected machine.

Kaspersky Lab researchers Vitaly Kamluk and Sergey Belov along with Annibal Sacco of Core Security demonstrated the flaw in a presentation at the Black Hat 2014 conference.
