When the screen is locked, Chrome OS prevents USB access

New security features will be added to Chrome OS, the web-based operating system that powers Google’s Chromebooks. USBGuard, a new feature, will prevent the USB port from being accessed while the device’s screen is locked. Canary builds of Chrome OS currently have this new feature and it is expected to be in the stable version of Chrome OS soon, as evidenced by a source code commit discovered earlier this week.

Consumers will be able to enable it by setting the “chrome:/flags/#enable-usbguard” Chrome OS flag. When the screen is locked and a USB is plugged in, this security function prevents the SO from executing or reading any code. Rubber Ducky-akin attacks were on the rise, thus Google implemented this safeguard to protect users. The term “rubber ducky” is commonly used to describe a malicious thumb drive that performs malicious commands and mimics a keyboard when connected to a device.

The Chrome operating system has supported Android apps for a long time, and as a result has Android Nougat running as a subsystem within Chrome. After two years of Nougat, the company is bringing it back as Android 9.0 Pie, rather than Android 8.0 Oreo. Chromebooks can take use of a wide range of new features and advancements in Android Pie. Many new features will be revealed in the media update for Chromebooks running Pie, but there are some changes that are immediately apparent in the latest release.

It’s hard to tell the difference between the new Settings app and the old one, but the new one has a lot more white space than the old one, according to media sources.
