Bluetooth Sharing must be disabled. Bluetooth Sharing allows users to wirelessly transmit files between the macOS and Bluetooth-enabled devices, including personally owned cellphones and tablets. A malicious user might introduce viruses or malware onto the system or extract sensitive files via Bluetooth Sharing. When Bluetooth Sharing is disabled, this risk is mitigated. [NOTE] ==== The check and fix are for the currently logged on user. To get the currently logged on user, run the following. [source,bash] ---- CURRENT_USER=$( /usr/sbin/scutil <<< "show State:/Users/ConsoleUser" | /usr/bin/awk '/Name :/ && ! /loginwindow/ { print $3 }' ) ---- ==== Satisfies: SRG-OS-000080-GPOS-00048,SRG-OS-000095-GPOS-00049

Verify the macOS system is configured to disable Bluetooth sharing with the following command:

/usr/bin/sudo -u "$CURRENT_USER" /usr/bin/defaults -currentHost read com.apple.Bluetooth PrefKeyServicesEnabled

If the result is not "0", this is a finding.
