"New Samsung Message Guard Protects Mobile Devices Against Zero-Click Exploits"
With the launch of its latest flagship Galaxy smartphones, Samsung recently introduced a new sandbox feature named Message Guard, designed to protect devices against zero-click exploits. Samsung noted that Galaxy smartphones, through the Knox platform, are already protected against attacks involving video and audio file formats. The new Message Guard feature protects phones against threats disguised as image attachments. Samsung stated that Samsung Message Guard is an advanced sandbox. When an image file arrives, it is trapped and isolated from the rest of the device. Samsung noted that this prevents malicious code from accessing the phone’s files or interacting with its operating system. Samsung Message Guard checks the file bit by bit and processes it in a controlled environment to ensure it cannot infect the rest of the device. Samsung stated that Message Guard works with the Samsung Messages and Messages by Google applications, but support will be extended to other messaging apps in the future. The new feature is currently available on Galaxy S23 smartphones, which Samsung launched on February 17. The tech giant said it will be gradually rolled out to other Galaxy phones and tablets later this year. Samsung noted that it will be available for devices running version 5.1 or higher of Samsung’s One UI user interface. The company said Message Guard is active by default and runs silently in the background.
