Samsung Message Guard stops zero-click exploits in image form

Samsung has long focused on the security of its smartphones. The Samsung Knox platform is built into Galaxy smartphones and already protects you against so-called zero-click exploits that aim to get hold of your data.

A zero-click exploit arrives in the form of an attachment and immediately sets to work to get control of your device or sensitive data. Samsung Knox already protects against such attachments in audio and video form, behind the scenes. Now, Galaxy users will be protected against exploits in image form too.

Samsung Message Guard is a sandbox of sorts, quarantining any image file that arrives on your phone and checking whether it's safe. The feature will work in Samsung and Google's Message apps at first but Samsung will roll it out to third-party messenger apps later this year.

A zero-click exploit is very dangerous because your phone could be hijacked and your data stolen while you're asleep or on the go.

Samsung Message Guard premiers on the Galaxy S23 series but is coming to other Galaxy devices later this year.
