Samsung announced on Friday it has developed a new security system to protect Galaxy S23 owners from image-based, zero-click exploits using a new virtual quarantine feature called Message Guard. These images require no interaction from the user to compromise the device.
Message Guard works by automatically placing any image file your phone receives into a virtual quarantine, otherwise known as a “sandbox” and “automatically neutralizes any potential threat hiding in image files before they have a chance to do you any harm,” explains Samsung.
Eventually, this protection will become a standard feature across the entire range of Samsung’s Galaxy devices.
David Maynor, Senior Director of Threat Intelligence, Cybrary had this to say:
“I am a fan of the forward-thinking Samsung does in their products, like DeX. DeX turns your phone into a desktop computing environment just by plugging in a monitor and keyboard. This means that Samsung’s mobile devices could face not just mobile attacks but the same attacks as any laptop/desktop user depending on installed software.
“Samsung already has Knox on mobile devices. Knox creates separate workspaces for a users personal data and a different one for work data. Message guard works in concert with Knox by attempting to detect attacks in each workspace by attackers looking to exploit zero-click exploits like those used by the NSO Group’s CNE software Pegasus.
“I use a Samsung Galaxy Fold 4 as both a personal and work phone and can’t wait for Message Guard to come to my platform.”
I have to admit that this is a cool feature that I hope not only appears in other Android phones, but makes its way over to iOS as zero click threats are the “holy grail” of threats as they don’t require any user interaction to execute. And the sooner that day comes, the better off we all will be.
