Reality Leigh Winner is in hot water thanks to a Xerox DocuColor printer. In May, Winner — an independent NSA contractor with high-security clearance who worked at Pluribus International here — anonymously sent classified documents to The Intercept about the Russian hacks during the 2016 U.S. presidential election. What Winner didn't know is that many printers use encoded watermarks — called steganography — that work as a way to track printed documents back to a specific device. Steganography works by printing small yellow dots in a pattern that can be decoded to reveal exactly what day and at what time a document was printed, as well as the serial number of the printer that was used. If convicted, Winner could face up to 10 years in prison.
