Galaxy S23 Gets Samsung Message Guard To Protect Against Zero-Click Hacks

In a press note announcing Samsung Message Guard, the company describes the solution as an advanced “sandbox” and a “virtual quarantine.” The primary objective of Message Guard is to isolate messages delivered to the smartphone before it can access the device’s files and operating system. Every time a text message is delivered to a Samsung smartphone protected by Message Guard, the tool checks the file bit by bit. This process happens in a controlled environment in such a way that it cannot infect the rest of the smartphone.

Samsung claims that the Message Guard tool preemptively neutralizes any threat hidden in text messages and image files before they could harm the device. What makes the tool even more effective is that it does not need to be enabled separately by the user, and runs invisibly in the background without needing any user interaction. 

In its current form, the tool works with Samsung’s own Messaging app as well as Google Messages. However, Samsung has promised a software update that will also widen the protection net to third-party messaging apps.

Samsung Message Guard is currently enabled by default on the company’s newest Galaxy S23 smartphones. However, the solution will roll out to a broader lineup of Galaxy smartphones and tablets later this year, the company confirmed.
