Samsung has introduced a new security tool called Auto Blocker as part of its recent One UI 6 update for Galaxy smartphone owners. This tool aims to protect users from potentially malicious software. Auto Blocker includes three main features, the first of which is the prevention of apps from being sideloaded or installed from “unauthorized sources.” This feature is designed to safeguard users against social engineering attacks where scammers try to convince them to install a harmful app. However, Samsung recognizes the benefits of sideloading and will not disable it completely. Instead, this feature will be turned off by default, allowing users to customize their devices and have greater control over functionality, given that they sideload safely.
Another feature of Auto Blocker is security checks for apps to detect any malicious activity on the user’s phone. However, it seems that American users may not have access to this tool, as Samsung states that it is currently unavailable on US carrier models. Nonetheless, all users will have the ability to block commands from a USB cable. This feature provides protection in scenarios where others may have physical access to the device, such as when charging a phone in public places like airports.
In addition to the core features, Auto Blocker offers some advanced options. Notably, the Message Guard upgrade provides protection against zero-click attacks, where malicious code is sent through messages. This upgrade covers texts from Messenger, Telegram, KakaoTalk, and WhatsApp.
Users can also choose to prevent software updates via USB cable, adding an extra layer of security when connecting a phone to an unknown USB port. Although not explicitly mentioned in the text, this feature appears in the announcement image, suggesting the possibility of hidden features.
To clarify any additional features and the availability of app security checks for US users, further inquiries were made to Samsung. Updates will be provided in due course.
Auto Blocker will be rolled out to all Galaxy devices compatible with One UI 6, including the Galaxy S23 series, S22 series, Z Fold 5, and Z Flip 5. Users are advised to be on the lookout for the patch when it becomes available.
