Samsung has created a new security feature called “Message Guard” to protect users against zero-click attacks that can install malware onto their devices without any user interaction. This feature is available on the Samsung Messages app and Google Messages for Galaxy S23 series devices, which have been released today.
Message Guard operates in the background and separates image files (such as PNG, JPG, JPEG, GIF, ICO, WEBP, BMP, and WBMP) from the rest of the device. The feature scans and examines these images bit by bit to ensure that they do not contain any harmful code that could potentially infect the user’s device.
However, “message guard” is a feature on some mobile devices that helps protect users from unwanted or harmful messages, such as spam or phishing attempts.
For instance, some phones may offer a built-in spam filter that automatically detects and blocks incoming messages from known spammers or suspicious sources. Other phones may allow users to create a “blocked list” of specific phone numbers or contacts that they wish to avoid.

Samsung has announced its plan to introduce Message Guard, a security feature that protects against zero-click attacks, to more of its Galaxy smartphones and tablets that run on One UI 5.1 or later. This feature will also be made available to third-party messaging apps through an upcoming update.
Zero-click attacks can go unnoticed by users while allowing hackers to access their data. Reports suggest that NSO Group spyware like Pegasus was installed on iPhones used by politicians, government officials, journalists, and activists through zero-click attacks.
To protect people from malware hidden in image attachments, Samsung has made a plan to add this feature. Besides this, there are also other useful tips to protect yourself from malware like, If you receive an email with an image attachment from an unknown sender or an unexpected source, it is best to delete the email or contact the sender to verify its authenticity before opening the attachment.
It is also vital to keep your operating system and software up to date with the latest security
patches and to practice good cybersecurity habits, for instance:
- avoiding suspicious websites
- and using strong, unique passwords.
