No one, not even the Secret Service, should randomly plug in a strange USB stick
It's a severe discredit to the major operating system vendors that plugging in a USB stick can still compromise a system.If a USB device identifies itself as a keyboard, the system shouldn't accept its keystrokes until that keyboard has typed the user's login password (EDIT: or the user explicitly authorizes the device using a different keyboard). If it identifies itself as a storage device, the filesystem driver should be hardened. If it identifies itself as an obscure 90s printer with a buggy driver written in C, it should prompt the user to confirm the device type before it loads the driver.It's 2019. Why the f* haven't Windows, MacOS and Linux all implemented these basic precautions?
