SCP-2519: "Cry Me A River"

Item Number SCP-2519 Object Class Safe Special Containment Procedures One instance of SCP-2519 is to be stored on a flash drive in a standard electronic item storage locker at Site 15.

Mobile Task Force Kappa-10 is to establish web crawler programs to detect sharing of SCP-2519 files, and is to investigate evidence of infection by SCP-2519 of known artificial intelligences.

Further testing of SCP-2519 is subject to permission from the Director of Site-15, and is to be conducted in a soundproof, airtight, Faraday-shielded testing room.

Description.

SCP-2519 is a digital audio file named Babylon.mp3, which encodes the three-part round, By the Waters of Babylon, based on the music written by Philip Hayes, 1738-1797, and set to the text of Psalm 137.

Audio analysis indicates that the recorded music is played by a small cylinder music box.

Electronic devices used to play the file, or mechanical systems exposed to audio playback of the file, are subject to one or more of the following effects.

Reduction in speed and efficiency of operation.

Leakage of oil and other fluids.

Cessation of function.

These effects continue for the duration of exposure, discontinuing when exposure ends, but in some cases have recurred at later intervals.

No apparent pattern has been determined as to which devices will experience recurrence of effects, nor the intervals at which these recurrences will occur.

SCP-2519 has not been observed to have any effect on living organisms.

SCP-2519 has the following additional effects where the capabilities of the exposed device permit.

duplication and automatic distribution of SCP-2519 to other devices on any accessible network.

The generation of additional data comprising new lines of music, designated SCP-2519-1, with harmonies based on the original round, these are added to the SCP-2519 file.

While these effects are typical for certain types of malware, the SCP-2519 file contains no data or code that would produce these results.

SCP-2519 has not been demonstrated to add additional capabilities to any device, and appears to be bound by the limitations of the equipment on which it is being played.

The existence of SCP-2519 was discovered through foundation monitoring of Darknet communications about a virus encoded within an otherwise normal MP3 file.

Following isolation of the original file, an additional 6,997 instances of SCP-2519-1 were also identified and contained.

Selected test logs follow.
