Have a wireless keyboard or mouse?  You might be susceptible to the “MouseJack” attack.  This is generally only possible while you are away and your device is unlocked.  But you never leave your device unlocked…  Right?  😉  

Countless wireless mice and keyboards are subject to “MouseJacking” including products from Amazon, Dell, Gigabyte, HP, Lenovo, Logitech and Microsoft.
