The smartphone battery can open everything that is typed or read on its screen
In a recent study conducted by experts from the University of Texas at Austin, the Hebrew University and the Israel Technion Technion Institute, it was found that a smartphone battery might have another unusual, previously unknown function. As it turned out, the power sources are able to record every keystroke pressing and can collect a large amount of confidential information, which hackers can eventually use.
The researchers implemented the microcontroller in the phone’s battery to record power fluctuations, both inside and outside. Then they connected the AI ??to calculate the correspondence of these oscillations to pressing the keys or the touch screen. Knowing such an algorithm, hackers will be able to write passwords and other confidential information of interest to them. All they need is for the smartphone to work from the battery, not from the network.
A similar method of tracking is already used in so-called smart batteries, which are increasingly found in modern smartphones. They control energy consumption with the help of applications and have functions that increase energy saving and increase battery life.
