When you are in public place like airport, cafe or on public transport and you charge your Smartphone via USB your phone can be easily hacked from there. Researchers at security firm Kaspersky Labs found that they could install a third-party application, like a virus, onto the phone via its USB cable connection to a computer. It took them under three minutes.
They also found that the Android and iOS phones tested leaked a host of private data to the computer they were connected to whilst charging, including the device name, device manufacturer, device type, serial number and even a list of files.
To protect your smartphone charge your phone only trusted computers using trusted USB cables. Protect your phone with a password or with another method such as finger print and don’t unlock it while charging. Ant viruses can be a bore, but they help to detect malware even if a “charging” vulnerability is used. Update your operating system to the most recent version as that will have the most up to date bug fixes.
