It's most likely how the FBI caught NSA leaker Reality Winner:
> Both journalists and security experts have suggested that The Intercept's handling of the documents, which included publishing the documents unredacted and including the printer tracking dots, was used to identify Winner as the leaker.

- shevy-java 1mo agoYeah - these criminal agencies use this to protect their billionaire buddies on top. The Epstein network must be really huge. I always wondered how one or two person can meta-coordinate +5000 underage girl and their +10000 customers. That never made any sense to me, yet suspiciously enough only Ghislaine is in prison. That does not add up.
- inigyou 1mo agoThere isn't just one Epstein network. There are many similar networks.
- davidwritesbugs 1mo agoThis seems like something that could be confirmed by reverse engineering a printer’s firmware? Surely someone has done that?
- circuit10 1mo agoIt is confirmed and the algorithm has been reverse engineered, though not by looking at firmware https://w2.eff.org/Privacy/printers/docucolor/ https://w2.eff.org/Privacy/printers/docucolor/ Seems like the algorithm is simple enough that they did it just by looking at some prints
- soco 1mo agoNo need to reverse engineer, printers are required to do this for decades.
- orthoxerox 1mo agoYou'd still need to reverse engineer it to build a better firmware without this anti-feature.
- bobim 1mo agoAnd the reason why it refuses to print this B&W document when yellow is empty.
- shuwix 1mo agoYou don't need reverse engineering if it's publicly known fact for 20+ years, telemetry just identifies you. 20 years ago, you would need to find the printer.
