Your attention , please . It's a final

00:03.019 --> 00:06.110
call for help . If you go to an airport ,

00:06.119 --> 00:08.286
you go to a public location , you have

00:08.286 --> 00:10.619
your cell phone and you wanna charge it .

00:10.850 --> 00:14.470
Be careful because uh USB

00:14.479 --> 00:16.899
devices have two capabilities behind

00:16.909 --> 00:18.965
them . They have power and they have

00:18.965 --> 00:21.360
data . If you're plugging into a random

00:21.370 --> 00:23.729
USB , you don't know if that data is

00:23.739 --> 00:25.739
going in or out . You don't know if

00:25.739 --> 00:27.850
you're getting something malicious or

00:27.850 --> 00:30.017
if your device is getting scanned . So

00:30.017 --> 00:31.149
don't plug into random USB device .
