Item #: SCP-CN-326
Object Class: Keter
Special Containment Procedures: Electronic copies of SCP-CN-326 are stored in the large-scale supercomputer "MAX.(period)" at Site-CN-46. Text copies of the object are likewise stored in Site-CN-46's document databases. Site-CN-46 will not be linked directly to any outside networks; rather, Site-CN-46 is to receive instructions from Foundation management through a telegraph line with Site-CN-47, located five kilometers away from Site-CN-46. In the event of SCP-CN-326 breaching containment, Site-CN-46's electromagnetic pulse explosives are to be detonated. At the same time, all connections between Site-CN-47 and the Foundation network or other outside networks is to be cut until the supercomputer "PARANOiA" takes over containment work and reestablishes Site-CN-46.
If Site-CN-47 is likewise breached, it is to constitute a containment failure and the Cytus plan is to be carried out immediately to minimize losses and reestablish containment. A single catastrophic containment failure is enough to cause devastating effects on the internet; in view of humanity's current reliance on the internet, this is likely to cause an IK-class Civilizational Collapse scenario.
A 20-km radius around Site-CN-46 and Site-CN-47 has been sealed off. No electronic devices are to be brought into the Site-CN-46-47 exclusion zone.
The entire text of SCP-CN-326, especially contents relating to the setting of the work, are not to be stored on any medium other than the hard disks of "MAX.(period)" and "PARANOiA", and may not be taken out of Site-CN-46 and Site-CN-47. The Foundation will prevent such an incident from occurring at all costs.
Description: SCP-CN-326 is the collective designation for a fictional universe known as "Becaloid" and a series of fantasy novels set in this universe. SCP-CN-326 was originally printed in a hardcover book titled Becaloid: Revolving Sounds - An Epic of Music Changing the World, which was copied onto Foundation networks on 24/2/20██ and is currently stored in isolation on the hard disks of the supercomputer "MAX.(period)". The contents of the original work were erased for unknown reasons following Incident CN-326-A.
When SCP-CN-326's contents are displayed in textual form, whether on paper or on a screen, all personnel within a 30-meter radius will hear a looping piece of music of varying length; despite this, no corresponding sound waves are recorded in the area. This music will also play from any devices connected to the one displaying the contents of SCP-CN-326. The content of the music corresponds to the location or event currently being described by the text. Although large numbers of instruments and singing voices are present in some cases, all personnel exposed to SCP-CN-326 reacted positively to this music. Current studies show that save for the positive reactions produced by listeners, this effect is harmless.
When recorded in traditional paper media, SCP-CN-326 is practically harmless. However, after Incident CN-326-A, all digital copies of SCP-CN-326, partial or in full1, are replaced with a file titled "Becaloid.world" of variable size, which immediately enter the assimilation stage, overwriting files stored on the same medium (henceforth designated SCP-CN-326-1), filling up all available space. This will render the SCP-CN-326-1 instance unusable as all data stored on it, including operating system files, are lost. The amount of time taken to assimilate all data varies based on the device and storage space, but typically lasts between 30 and 120 seconds. As soon as the assimilation stage begins, there is no way to interrupt or reverse it other than destroying the instance of SCP-CN-326-1; in addition, SCP-CN-326-1 will continue to function without connection to power.
Display devices connected to SCP-CN-326-1 will begin displaying SCP-CN-326's contents in various writing systems2. If SCP-CN-326-1 is connected to a printer, it will begin printing the same contents onto any available paper.
It is worth noting that SCP-CN-326-1 used in testing appear to be operating under heavy or even excessive load, and according to Dr. Mitsuru's analysis, SCP-CN-326-1 may be running one or several programs.
Addendum CN326-A: Spreading of SCP-CN-326
SCP-CN-326 has a strong tendency to spread. It expands by sending a hard-to-intercept packet over all wired or wireless connections; all methods of blocking these packets short of disrupting the physical connection have ended in failure. The packet contains a file called "Becaloid.seed", 573 bytes in size; all devices that receive this packet enter the assimilation stage and become instances of SCP-CN-326-1 within one minute, and transmit an identical packet to all connected devices.
The intensity of SCP-CN-326's spreading behavior seems to be related to the number of SCP-CN-326-1, their hardware capabilities and their storage capacity. Researchers have discovered that when all SCP-CN-326-1 instances have filled up all available storage, SCP-CN-326 will begin to spread. Currently, the one Foundation VII-type supercomputer currently being converted into SCP-CN-326-1 is sufficient to prevent the spread of SCP-CN-326.
If all SCP-CN-326-1 are destroyed or incapacitated, the device closest to the last remaining SCP-CN-326-1 will become an instance of SCP-CN-326-1 itself and may also begin spreading depending on prior conditions.
It is worth noting that with the passage of time, the load produced by SCP-CN-326 on SCP-CN-326-1 will slowly increase. Simultaneously, the contents of SCP-CN-326 will also update, including more information on characters within the story and further developments along its timeline. All new content has been archived in paper form.
Incident CN-326-A: Following the discovery that SCP-CN-326's anomalous properties can activate even on electronic media, Dr. Mitsuru recommended that SCP-CN-326's contents be copied onto Foundation databases and archived in the name of "increasing the efficiency of research". This recommendation was approved by Site-CN-71 Director ███████, and SCP-CN-326 was successfully archived over the period of 19/2/20██ to 24/2/20██. Following this, all research was carried out on the digital version.
On 5/3/20██, Site-CN-71's Server #3 was infiltrated by unknown hackers, who retreated before the Cybersecurity Department could launch counterattacks. Following this, Server #3 became an instance of SCP-CN-326-1 over the next 1 minute and 25 seconds, and spread SCP-CN-326 to a large proportion of Site-CN-71's servers. Although Site-CN-71's external connections and intranet were quickly deactivated, five servers, most of the site's mobile devices, and a large portion of the central control system were compromised and became SCP-CN-326-1, and were operating under heavy load. Personnel estimated that SCP-CN-326-1 would collapse in as soon as a month, causing unknown consequences.
Following further research into SCP-CN-326-1's properties, the Foundation repurposed Site-CN-46, located in ██████, Guangxi Province, and its VII-type supercomputer "MAX.(period)", originally used for weather simulations, on 12/3/20██, and loaded SCP-CN-326 onto it to convert it into SCP-CN-326-1. Following this, the area around Ste-CN-46 was sealed off and Site-CN-47 was established nearby as a communications relay station and buffer area, establishing new containment procedures.
Following "MAX.(period)"'s conversion into SCP-CN-326-1, the load of all SCP-CN-326-1 in other areas reverted to normal, and the Foundation managed to complete cleanup operations. All SCP-CN-326-1 in Site-CN-71 were dismantled. Site-CN-71 was fully repaired on 25/3/20██, and resumed operations the next day.
Data lost at Site-CN-71 owing to the incident exceeded 85%, including historical documents, experiment logs, personnel dossiers, and personal files of personnel. ██ SCP documents were lost and had to be recreated. 43% of Site-CN-71 was inactivated due to damage to the central control system. The containment rooms of SCP-CN-███, SCP-CN-███, and SCP-CN-███ failed as a result, and these anomalies were transferred to other Sites. Photographs and photocopies of SCP-CN-326's contents prior to Incident CN-326-A, could not be found. The original book containing SCP-CN-326 has been archived in a Low-Value Storage Safe.
Addendum CN326-B: Incident CN-326-A Postmortem Report:
The Cybersecurity Department reviewed the records3, and discovered that the hackers had modified and overwritten the copy of SCP-CN-326 stored on Server #3. When compared to the version stored on "MAX.(period)", it was discovered that part of SCP-CN-326's last chapter, Fourth Period, Year 750: The Dawn of the Sky, had been maliciously destroyed, rendering the full content unreadable. Researchers are currently investigating the link between this segment of text and SCP-CN-326's sudden change in anomalous properties.
The Cybersecurity Department attempted to track the hackers involved in attacking Site-CN-71, but failed. However, judging by the style of the text left behind by the intruder and the manner in which the actions were performed, it is suspected that the identity of the hacker is PoI-9481, also known as "Mia.S". This person has repeatedly attacked Foundation databases and caused large amounts of information leakage. Based on currently known data, the suspect is not formally associated with any Groups of Interest, but is reportedly very close to certain members of the Serpent's Hand.
For further information on the affected data, refer to Appendix CN326-B.

Note: This is the only part of SCP-CN-326 that does not show any anomalous properties. It's really a shame, isn't it?
By decree of Site Director, this document is classified for Level 4 or higher eyes only. However, Level 3 or higher personnel at Site-CN-46 may view this document.
