While examining various Apple notebooks, such as MacBook Airs, MacBook Pros, and MacBooks for their batteries, Miller discovered that the microcontroller chips inside the laptops contained default passwords, which if hacked could let malware purveyors intervene the system.
He stated that the batteries with default passwords were not constructed for anyone to muddle with them but it the functionalities of these components were truly vicious, as reported by PCWorld.
Further, Miller examined software update (2009), which Apple had utilized for rectifying an issue affecting MacBook batteries, and found passwords in the laptops that could help change the batteries. So when he succeeded in accessing them, he also succeeded in altering the chips' capability so they would display only those readings that favored him.
Besides during his experiments, Miller succeeded in blocking 7 batteries accounting for about $130 each. However, cyber-crooks who were able to load malware, which contaminated the laptop's other parts, found it easy to control the notebook's activities, steal data, or even take over it. Normally, an IT administrator would not imagine an infection in the firmware of the battery, so incase it is not detected, the computer could be repeatedly infected.
