Item #: SCP-2801

Object Class: Keter

Special Containment Procedures: All SCP-2801 variants are considered highly infectious. No more than two SCP-2801-1 instances are to be held at any given facility, and all instances not held for research purposes are to be terminated or administered Class-F amnestics. Instances held for research are to be contained in soundproofed humanoid containment chambers. Psionic scramblers are to be placed outside these chambers to prevent SCP-2801-1 instances from receiving or transmitting psionic signals. If an SCP-2801-1 instance must be removed from one of these chambers, they are to be rendered unconscious by two deaf D-class personnel before being transported.

All newly hired personnel are to undergo screening for SCP-2801 infection. D-class personnel are to be screened on a weekly basis, MTF personnel are to be screened on a biweekly basis as well as immediately after operations, and all other personnel are to be screened on a monthly basis. If a D-class personnel is found to be an instance of SCP-2801-1, all D-class in the instance's assigned barracks are to be immediately quarantined until diagnosis.

Foundation webcrawlers are to monitor file-sharing websites and hacker forums for uploads and mentions of Neurocrack and other cognitohazard creation software. Upon detection, these uploads are to be taken down as quickly as possible.

Additional variant-specific containment procedures may be required. Contact the SCP-2801 project director for more details.

Description: SCP-2801 collectively refers to a series of self-propogating neurological phenomena affecting human brain function. These phenomena (individually referred to as SCP-2801 “variants”) have been recorded affecting various human individuals (hereafter referred to as SCP-2801-1), regardless of physical or mental differences. There are currently over 300 unique variants of SCP-2801, each with different behavioral characteristics and symptoms.1

While some variants may use additional means of infection, SCP-2801-1 speech serves as the primary transmission vector for SCP-2801. Although SCP-2801-1 speech is reported as indistinguishable from speech generated by uninfected persons by 97% of listeners, SCP-2801-1 speech is a Class-B cognitohazard, exposure to which, whether in person or through a recording, causes the listener to begin showing signs of infection by the SCP-2801-1's variant(s) within thirty minutes.2 Both the listener and the SCP-2801-1 instance are completely unaware of this process.

SCP-2801-1 instances frequently transmit low-frequency psionic signals, although the conditions under which this occurs is dependent on the variant. Although there is no method as of yet to interpret these signals, they can easily be detected through use of a Kasra-Warren reader or other such equipment. In addition, SCP-2801-1 often re-transmit any signals received, suggesting that these signals may be used as part of a communication network. SCP-2801-1 instances are unaware of both transmission and reception of signals, although roughly 1.3% of instances report mild headaches when receiving or transmitting a large volume of signals.

SCP-2801 variants are created through the use of a piece of software for Linux computers referred to as Neurocrack, first distributed on a number of hacker forums under various screen names on 2017/6/15. The software has been redistributed multiple times since from various sources. This software is capable of generating cognitohazards in the form of audio and image files, using a variety of common formats. The effects of the hazards generated are determined by user-written code similar in syntax to the C programming language, making Neurocrack much more versatile than any other cognitohazard creation software currently known to the Foundation. Neurocrack is believed to have been created, at least in part, by an individual designated POI-7684.

Although some variants may be mitigated by other means, the only known effective treatment for SCP-2801 infection is the use of Class-F amnestics. As this results in total memory loss and often extensive brain damage to the host, research into a less damaging treatment is currently underway.

Addendum 2801.1: SCP-2801 was discovered on 2017/2/4 during research on SCP-███, at which time a Kasra-Warren reader was being used to detect psionic signals. During the experiment, the reader displayed an abnormally high amount of low-frequency psionic signals. As this volume of signals had never been detected as part of normal SCP-███ behavior, this was believed to believed to be the result of a malfunction until an additional device was used to confirm these readings. The D-class personnel used during testing was later found to have been accountable for roughly 53% of the signals detected in the experiment. Further testing indicated similar psionic signals transmitted by 96% of the D-class personnel assigned to barracks B (which the D-class it was initially detected in was assigned to)3. The condition was designated SCP-2801, and all D-class in barracks B were put under quarantine.

Addendum 2801.2: Below are descriptions of SCP-2801 variants that are notable either due to unique behavior or correlation to notable incidents. A complete list of variants is available upon request.

Addendum 2801.3: POI-7684, the creator of SCP-2801-A and the Neurocrack software, was identified by Foundation investigators on 2018/1/3 as a freelance computer programmer living in the city of Dallas, Texas under the name of Nathan Snyder. POI-7684 had created SCP-2801-A with the help of colleague Daniel Yu, a neuroscientist working for [REDACTED].

On 2018/4/17, raids were conducted on the residences of both POI-7684 and Daniel Yu. POI-7684 was not present at his apartment, and the apartment complex's owner indicated that POI-7684 had not returned to his apartment since leaving with a number of electronics the previous afternoon. A search of POI-7684's apartment revealed nothing indicating POI-7684's whereabouts or any materials related to SCP-2801 or the Neurocrack software.

Daniel Yu was located at his apartment deleting a number of digital files related to POI-7684 and SCP-2801 and was taken into Foundation custody. Daniel Yu later claimed no knowledge of POI-7684, SCP-2801, or the Neurocrack software, even while under duress. When asked what he had been doing before the raid, Yu claimed that he had checked his voicemail, but could remember nothing afterwards. All files pertaining to POI-7684 or SCP-2801 recovered from the Yu residence are listed below.

Yu was administered Class-A amnestics, screened for SCP-2801 infection, and released from Foundation custody on 2018/1/13. The location and status of POI-7684 remains unknown.
