Samsung launches ‘Message Guard’, which protects users against Zero Click Attacks
Samsung has developed a new security solution, known as Samsung Message Guard, to protect Galaxy smartphone users from so-called “zero-click” vulnerabilities that use malicious image files. The Korean tech giant claims its new security system could detect these threats as soon as they reach the device as a message and stop them before they can do any damage.
In general, attacks that exploit zero-click vulnerabilities involve delivering a message or file containing malicious code to the target to exploit a device vulnerability that allows the attacker access without the victim even knowing the message or file. is reading.
Significant zero-click attacks used Apple’s iMessage KISMET and FORCEDENTRY vulnerabilities to target journalists and activists with NSO’s Pegasus spyware. Apple attempted to address these security vulnerabilities by creating Lockdown Mode, a mode of operation for high-risk users that restricts functionality and increases device security.
On the other hand, Samsung Message Guard is a separate virtual space on the smartphone that serves as a temporary host for newly received image files in PNG, JPG/JPEG, GIF, ICO, WEBP, BMP, and WBMP formats. The system examines the files to determine whether or not they hide malicious code. If so, they will not be able to access or interact with the underlying operating system and will be placed in quarantine mode.
In this regard, the company said,
Samsung Message Guard instantly neutralizes any potential danger hidden in image files before they can harm you.
