Even when your Chromebook is locked, dangerous actors can entry it utilizing a “Rubber Ducky,” or malicious USB drive that mimics a keyboard. Chrome OS will quickly put a cease to these assaults with a function known as USB-Guard, seen in a Canary Chrome build by Chrome Story. It stops the working system from studying code or executing instructions from USB units when your Chromebook is locked. The characteristic is just like what Apple introduced in the latest construct of IOS 11 that stops USB exercise if a tool has been secured for more than an hour.
Units already plugged right into a Chromebook when it is locked will proceed to operate, guaranteeing information transfers will not cease, as an illustration. As soon as the characteristic arrives, you must be capable of deciding in to make use of the service and whitelist USB gadgets like a keyboard or mouse.
Chromebooks are thought of safer than Home windows and different gadgets, particularly for clueless customers (I am speaking to you, Aunt Gertrude with six adware toolbars). Nevertheless, any laptop will be susceptible to Rubber Ducky devices, primarily small computer systems that pose as keyboards and inject pre-programmed keystroke sequences at as much as 1,000 wpm. All of this may be stopped simply be disabling the USB port, so the USB-Guard characteristic — coming to Chromebooks within the close to future — is welcome information.
