8 Real Steganography Cases and How They Got Caught

In 2002, USA Today reported that al-Qaeda was hiding encrypted messages inside eBay images. Two University of Michigan researchers scanned two million eBay pictures and found nothing — and that gap between headline and evidence is where this episode begins. We count down eight documented cases of steganography actually used in the wild, from a World War I null cipher that spelled out Pershing's sailing date in the first letter of every word, to a Manhattan doll shop whose letters described warships as dolls, to a Navy pilot who blinked TORTURE in Morse code during a televised 1966 interview. The through-line is startling: almost none of these messages were caught by the hidden payload itself. A caption, an envelope, a run of hotel typewriters, a microphone — something else always gave it away. We dig into what each case reveals about how real covert communication succeeds, why dull covers beat clever ones, and why a clean scan of two million images proves less than it seems.
