Kaspersky has warned against charging your smartphone via public USB outlets and even your own PC or Mac.
A concept presented at the Black Hat security conference in 2014 demonstrated how you probably shouldn't use public smartphone charging stations, as hooking up to a fake one could see malware loaded onto your device.
Kaspersky has been looking into this more and, as part of a study into the dangers of charging your handset at a public charging station, tested a number of devices using iOS and Android to see what data is transferred externally while connected to a Mac or PC.

Kaspersky Report:
"As part of this research, the company’s experts tested a number of smartphones running various versions of Android and iOS operating systems in order to understand what data the device transfers externally while connected to a PC or Mac for charging.
The test results indicate that the mobiles reveal a whole litany of data to the computer during the ‘handshake’ (a process of introduction between the device and the PC/Mac it is connected to), including:
- the device name
- device manufacturer
- device type
- serial number
- firmware information
- operating system information
- file system/file list
- electronic chip ID
Is this a security issue? Indirectly it is."
