@bn+1 It's been mentioned before and apparently not taken seriously, but this guy was caught by Information Security.
They have automation which monitors all devices plugged into the intel network.
They even know the serial number and internal identification of the USB, as well as every device it was ever plugged into (this last part is after its use has been detected and they are able to scan it).
The only approved way to get documents off your laptop is to email them to yourself. All emails are also scanned and the email should fail if it contains sensitive info.
Don't even do that in bulk, or you'll be up for scrutiny.
This is not a joke.
