Samsung has developed a new security system called Samsung Message Guard to help Galaxy smartphone users keep safe from the so-called "Zero-click" exploits that use malicious image files.
Typically, attacks relying on zero-click exploits involve sending the target a message or file with malicious code to trigger a vulnerability on the device that gives the attacker access without the victim even opening the message or file.
Samsung Message Guard is an isolated virtual space on the smartphone that acts as a temporary hosting location for newly arrived image files in PNG, JPG/JPEG, GIF, ICO, WEBP, BMP, and WBMP formats.
"Samsung Message Guard automatically neutralizes any potential threat hiding in image files before they have a chance to do you any harm," explains Samsung in the feature announcement.
The new security system is added to Samsung's multiple existing protection layers, most notably Samsung Knox, which can offer real-time threat detection and protection against malware.
Samsung Message Guard is available immediately for Galaxy S23, released on Friday, and it will gradually roll out to other Galaxy devices running One UI 5.1 or higher later in 2023.
