Charlie Miller, well known for his numerous attacks on iPhones and Macs, may not have achieved his ultimate objective of making a Mac spontaneously combust, but he has figured out how to permanently disable the battery. And in time, he said, it also may be possible to remotely hijack a machine by manipulating the firmware on one of the stored power supply's chips.
"What I found was you can make any change you want to the software that runs on the battery," Miller, who is principal research consultant at security firm Accuvant and the other coauthor of The Mac Hacker's Handbook, told The Reg. "I also saw that you can mess up the chip so it won't function anymore. You can't recover from that. You couldn't even take it to the genius bar."
