One UI 9 has a feature to disconnect the USB-C port data connection, preventing Juice Jacking

On the One UI 9 update, Samsung has upgraded the Auto Blocker feature to a new level through the "Maximum Restrictions" mode, which completely disables the risk of being hacked when charging in public. If on One UI 8.5, the device only blocks software commands such as adb commands but the physical connection between the phone and computer/charging source is still open, hackers can still exploit security holes at the deep level of the system. Updating security on One UI 9 with the Auto Blocker feature - Maximum Restrictions mode will completely disconnect the data transmission channel of the USB microcontroller, thus the pins responsible for data transmission on the device's USB-C port will be disabled, the USB-C port's only function is to receive current to charge the battery. Auto Blocker is a very good solution to deal with Juice Jacking - hacking through public charging sockets, often in stations, airport lounges, shopping centers... Hackers will install additional circuits containing malicious code into public sockets. When the user plugs in the charger, malicious code will immediately be installed on the device, thereby silently stealing data and sensitive information. With Auto Blocker, hackers will not be able to deploy this tactic because the data connection between the socket and the phone has been physically disconnected. However, this mode also affects other usage situations such as connecting Android Auto wired, transferring files to a computer, running adb commands or USB Debugging, connecting the phone to peripheral devices via USB ports such as hard drives, card readers, cameras... Therefore, users need to proactively turn Maximum Restrictions mode on or off. If there is no need to connect data to external devices, it is best to leave it turned on for safety. Sammy Fans
