11B-X-1371 is the name given to a late 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.
