One of the primary focuses of Samsung’s Auto Blocker is its ability to prevent the sideloading of harmful apps on Samsung devices. For experienced users who choose to sideload apps, the experience remains unchanged on devices running One UI 6 because the Auto Blocker feature is turned off by default.
Auto Blocker may prove especially helpful during possible social engineering attacks, where inexperienced users are tricked into installing a malicious app from unverified sources. The tool also allows users to protect themselves from phishing attacks by blocking malicious commands sent to their device via a USB cable. This feature could be particularly useful for inexperienced users unaware of the danger of public USB charging sockets.
In addition to the new Auto Blocker tool, the One UI 6 update includes a significant enhancement to the Message Guard feature, announced a few months ago. Message Guard was initially designed to mitigate zero-click attacks initiated via text messages. It now extends its protection to prevent zero-click attacks via popular messaging apps like Facebook Messenger, Telegram, and WhatsApp.
