I find this easy to believe, but a bit surprising that it’s not mentioned or studied or even has crank/subversive pages with POC detections. The printer/scanner steganographic fingerprints became pretty well-known within a few years of becoming common.
I mean, anything that’s aggressively online (m365 versions of excel, Windows itself, Google Sheets, etc.) should be assumed to be insecure against state-level threats. But if you’ve got evidence of specific backdoors or monitoring, that should be shared and common knowledge.
