Not the authorities perhaps, but it is already happening in some degree: Windows Defender sending “samples” or unknown binaries to the cloud to analyze them. I am extremely bothered by this and try to disable this “feature” as much as possible. As always with Windows, you have to aggressively tweak system settings to permanently disable the constant reminders “Oops we have detected suboptimal settings, please turn on every privacy invading feature for your convenience”. We can only hope MS doesn’t abuse the samples for other purposes, but given their and other big techs track record, we can assume there are additional parties interested in the submissions.
