Samsung has launched a brand new Message Guard safety function for its Galaxy vary of smartphones and tablets that may higher defend customers towards “zero-click” cyberattacks disguised as picture attachments in messages. Zero-click assaults — which set up adware and different malicious code onto units with none interplay from the proprietor — have grow to be more and more frequent over the previous couple of years.

When a Galaxy machine receives a textual content message with a picture attachment, Message Guard isolates the picture file from the remainder of your machine to lock down any probably malicious code. The function then scans the picture earlier than processing it to make sure it could possibly’t infect the machine.

Samsung Message Guard is accessible now on Galaxy S23 collection telephones (in the stores from in the present day, February seventeenth) and can ultimately be rolled out to different Galaxy smartphones and tablets working One UI 5.1 or greater in some unspecified time in the future later this yr. The Message Guard function at present works on Samsung Messages and Messages by Google, and can ultimately be made obtainable to undisclosed third-party messaging apps through a software program replace “at a later date.” Message Guard doesn’t must be activated by the consumer and runs “silently and largely invisibly within the background,” in line with Samsung.
