The Plague Doctor

This internet enigma is officially called as 11B-X-1371, and for a while it was hailed as the spookiest YouTube video. In a two-minute black-and-white footage, a figure dressed as a plague doctor is seen standing inside a run-down structure with a forest behind them. Static noises accompany the footage, and the figure is holding a blinking light in its hand that seems to be transmitting messages in Morse code.

When a tech site called GadgetZZ first made the clip public in 2015, it quickly became popular online. As individuals continued to look into it, they found that the movie had a lot of unpleasant material, including strange words, threats, and even violent images that were encoded in plaintext, Morse code, and the audio's spectrogram.

Online rumor mills suggested that the film might have been a hoax, a student project, a viral marketing gimmick, or even something more serious like the work of a serial killer or a bioterrorism threat. The external pictures of the woodland helped investigators locate the spot where the video was filmed after weeks of searching. It was a defunct psychiatric hospital in Poland that located close to the town of Otwock. Finding the video's creator's identity was the next step.

This proved challenging because numerous people attempted to claim authorship and numerous others produced imitation clips, but a few months later, the author was tentatively identified using the pseudonym Parker Warner Wright. He said he was an American residing in Poland who made the film as a creative endeavor.
