Vulnerability Discussion

Handoff must be disabled.

Handoff allows users to continue working on a document or project when the user switches from one Apple device to another. Disabling Handoff prevents data transfers to unauthorized devices.

Check

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

/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\
.objectForKey('allowActivityContinuation').js
EOS

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

Fix

Configure the macOS system to disable Handoff by installing the "com.apple.applicationaccess" configuration profile.
