Kaspersky\'s experts, curious to determine the data transmitted externally when a smartphone is connected to a PC or Mac for charging, tested some phones running on various versions of Android and iOS operating systems.
After their research, the experts concluded that \"a lot of\" data was transmitted during the \"handshake\" between the two devices.
That is, the introduction process between the device and the laptop it connects.
During this period, the phone shares the device name, manufacturer, type, serial number, firmware information, operating system information, file system/file list, and electronic chip ID.
\"The amount of data sent during the handshake varies from device to host, but each smartphone transmits the same set of basic information. . .

All in all, Kaspersky researcher Alexey Komarov said it was \"strange to see this after nearly two years of publication of a piece of evidenceof-
The concept shows how smartphones can be infected via USB, and it still works.
He added, \"you don\'t even need to take it seriously --
For this kind of attack, all the information you write can be easily found on the Internet.
