11B-X-1371

11B-X-1371 is the name given to an early 2015 viral video of unknown origin, derived from the plaintext of a base64 string written on a DVD sent to GadgetZZ.com, the Swedish tech blog that publicized it. The segment is two minutes in length, consisting of black-and-white footage of a person wearing what appears to be a plague doctor costume walking and standing around in a dilapidated abandoned building with a forest visible through former window openings in the wall behind it. Accompanied by a soundtrack of loud, discordant buzzing noise, the masked figure holds up a hand with an irregularly blinking light. Viewers have described the experience of watching it for the first time as "creepy" and "unsettling", likening it to the experience of watching the video in the 2002 film The Ring.

Messages, many in commonly used ciphers and encryption systems, have been found hidden in the video and its sound spectrogram, as well as disturbing images of tortured and mutilated women. Most of the messages have been decoded by participants in an ongoing Reddit thread, and the images sourced to notable murder investigations such as the Boston Strangler. They have been interpreted as implying a threat of bioterrorism against the United States, although it has also been speculated that the video is in reality a viral marketing stunt for an upcoming film or video game, or a student film.
