A new type of vulnerability may be on the forefront, a battery vulnerability. Newer batteries have a PCB that monitor charge levels, initiate charging, and regulate heat. According to Charlie Miller, a leading security expert, batteries in the new Macbooks are shipped with the default username and password. This default username and password is designed to allow Apple to send out updates to the battery. Unfortuneatly, this also allows criminals to exploit the battery and place malware on them or even overcharge the battery, possibly leading to an explosion.
This goes to show that in IT security you need to stay up to date as to what the latest threats are. Not many security professionals would think to check the battery. Staying up to date is the best way to protect your IT resources from harm.
