I recently bought a Dell laptop and found out that Dell recommends to install a theft-protection system called LoJack. It is a system installed on the BIOS; if the laptop is stolen, it is possible to connect to their website to locate the laptop, delete files on it, etc. Since it sits on the BIOS, it cannot be removed by formatting the hard-drive.
It seems like a good security measure. On the other hand, it seems to give a lot of power to the company behind LoJack; apparently, any of their employees can now control my laptop remotely.
So, my question is: do I put myself on risk by installing such a theft-protection system on my laptop? Are there known cases where a laptop was taken control of using such a system?
