In World War II, German spies used a technique called the "microdot" to embed secret messages within seemingly innocuous documents. The microdot technique involved shrinking the text of a message to the size of a small dot (about 1 millimeter in diameter) and then placing it within the text or image of a cover document, such as a letter or newspaper article. The recipient would need a microscope to read the tiny message. The Least Significant Bit method is used frequently for the legitimate use of watermarking image, video and audio IP. It is a simple technique that embeds the watermark data into the rightmost bit of a binary number (LSB) of some pixels of the cover image. It is also very common for malware to hide it's configuration data or payload within image files. (ZeusVM, Zberp, NetTraveler, Shamoon, Zero.T)

  In one of those historic ironic twists, the technology the Germans used to make microdots was created by a Jewish inventor, Emanuel Goldberg.

Specifically, Zheng is alleged to have used steganography to hide data files belonging to GE into an innocuous looking digital picture of a sunset, and then to have e-mailed the digital picture, which contained the stolen GE data files, to Zheng’s e-mail account.

    If they didn't we would never know, would we? We must do something like the Border Patrol does when they seize like 1kg of drugs and use that to assume that 1,000kg got through.

In 2010, the Colombian government commissioned a pop song called "Better Days" that received nationwide airplay. Hidden within the song was a Morse code message for FARC hostages (some of whom were soldiers and trained in Morse) that help was on the way. https://www.bbc.com/news/world-latin-america-63995293 https://www.bbc.com/news/world-latin-america-63995293
