Samsung has announced Auto Blocker, a new addition to its security features available on Galaxy devices running the One UI 6 interface.

This new package aims to give users more control over their device’s security measures.

Auto Blocker happens to be an opt-in feature that comes with various capabilities, including preventing sideloading and offering security checks for apps.

User-Centric Design Philosophy

Dr. Seungwon Shin, EVP & Head of Security Team at Samsung Electronics, stated that the company aims to put the control back in the hands of users.

According to Dr. Shin, Samsung is focused on allowing users to choose the level of security that best meets their needs rather than making that decision for them.

Features of Auto Blocker

• Prevention of App Sideloads: The feature prevents the installation of apps from unauthorized sources, an activity commonly known as sideloading.
  However, for users who intentionally sideload apps for enhanced customization, this feature is turned off by default.
• App Security Checks: Auto Blocker also provides the ability to turn on security checks for apps, aimed at detecting potential malware.
• USB Security: It prevents harmful software installations that could happen through a USB cable—important for scenarios where someone could have physical access to the device.
• Message Guard Update: An update has been provided to the existing Message Guard feature, designed to mitigate Zero Click attacks, particularly those that come from image messages in third-party apps.

Security in Open Ecosystems

Auto Blocker supports the idea of an open ecosystem by providing an opt-in package of additional security measures.

It does not interfere with users who prefer to sideload apps but offers an extra layer of security to those who wish to avoid potential threats like voice phishing attacks or social engineering tactics.
