Samsung has developed a new security system called Samsung Message Guard to help Galaxy users maintain protection against the so-called “zero-click”
The system will be able to detect threats when they reach the device as a message and stop them before they cause any damage.
Typically, attacks that rely on a “zero-click” exploit involve sending a message or file to the victim with malicious code to trigger a vulnerability on the device that gives the attacker access without the victim even opening the message or file.
Prominent zero-click attacks targeted journalists and activists with NSO’s Pegasus spyware by leveraging KISMET and FORCEDENTRY in Apple’s iMessage.
The Samsung Message Guard system is an isolated virtual space on the smartphone that acts as a temporary host for image files that came in PNG, JPG/JPEG, GIF, ICO, WEBP, BMP and WBMP formats.
The system checks the files to determine if they hide malicious code. If so, they will be locked in quarantine and blocked from accessing or interacting with the underlying operating system.
Samsung Message Guard is available immediately for the Galaxy S23, which was released on Friday, and will gradually roll out to other Galaxy devices with One UI 5.1 and above later in 2023.
