Exploiting Smart-Phone USB Connectivity for Fun and Profit 1
New Malware Tries to Infect Android Devices Via USB Cable 2
When charging a device, avoid connecting mobile devices directly to computers, and prefer the use of simple corded chargers obtained directly from the device vendor.
To prevent some attacks over USB connectivity, disable USB debugging on Android devices when that feature is not in use.
To reduce the opportunity for an attacker to directly connect a device to a malicious computer, use strong physical security when a device is being left directly unattended (e.g., lock it in a secure container).
To prevent some attacks over USB connectivity, ensure the device has an unlock code set and is explicitly locked when being left directly unattended.
