Samsung improve the level of protection of Galaxy smartphones vs zero-click exploits with Message Guarda tool available both on the proprietary Messages app and on Google Messages which “takes security to the next level by proactively protecting your device, limiting exposure to invisible threats masquerading as image attachments“.
Samsung Message Guard is defined by the South Korean company as a sort of virtual quarantineone sandbox in which the received image is isolated from the rest of the device so as to prevent any malicious code from coming into contact with the smartphone files or with the operating system. The tool checks “bit by bit” in a “controlled environment“.
Samsung Message Guard protects files with PNG, JPG/JPEG, GIF, ICO, WEBP, BMP, WBMP format.
Its peculiarity is that it works in the background, silently, without the user noticing anything. Message Guard is activated by default e it does not replace Samsung Knox:
Samsung Galaxy devices already provide privacy and security protections […] Thanks to Samsung Knox. This provides end-to-end protection across every layer of hardware and software, as well as real-time threat detection.
