Here’s a question for you. If you wanted to create some piece of malware that would survive replacing the hard drive, flashing the BIOS, and reinstalling the O/S from a clean set of disks, and with no network connection, how would you do it? Seems impossible, doesn’t it? How could an infection get back in without any way for the infection to have survived the “wipe and start over” process?
Well, a well-known hacker named Charlie Miller found a way… the battery.
