SCP-3959 affected road sign
Item #: SCP-3959
Object Class: Keter
Special Containment Procedures: SCP-3959 cannot be contained or destroyed by any known methods. At this time, implementing a means of deterring SCP-3959 from reaching SCP-3959-1 is considered a top priority. All Foundation documents are to be secured in Site-01, currently being constructed as a repository for archived files. Falsified documents are to be distributed to sites of interest. These documents are to contain as much correct data as possible, while remaining less than 50% factual. This has been shown to deter SCP-3959's consumption. Despite this, SCP-3959 is capable of and most likely has intention of consuming the entirety of information itself.
SCP-3959-1 is to be contained in a maximum security chamber within Site-██, sealed with a triple lead-lined Faraday cage. Periodic inspections of SCP-3959-1 are to take place daily by a trained member of the research team. In addition, this document should be the only record of SCP-3959-1's existence.
At no time are any forms of information to be brought into SCP-3959-1's containment area.
Description: SCP-3959 is the designation for an extremely hostile rogue Class VIII cognitohazard, formerly referred to as Algorithm A3EN1. SCP-3959 was created as a part of the now defunct Project Callisto as an attempt to weaponize information. Despite multitudes of documentation, all involved have no recollection of having participated in the project.
SCP-3959 has infovorous tendencies, as was expected as part of the project's outline. SCP-3959 will gravitate towards large volumes of data in attempt to consume it. Items currently being "fed" on automatically redact their own information, as well as generating a powerful antimemetic effect. Any information consumed by SCP-3959 is essentially permanently lost, both from all documentation and all of human memory. Whether SCP-3959 is causing a retroactive change in causality or simply erasing all knowledge of the affected information remains unknown, and due to the aforementioned antimemetic effects, may never be discovered.
At no time should SCP-3959 come in contact with SCP-140.
Although SCP-3959 prefers large quantities of data, it has shown to be most interested in returning to SCP-3959-1.
SCP-3959-1 refers to former Anomalous Item 38719 (See Log of Anomalous Items for a complete list). SCP-3959-1 is a large, indestructible textbook of unknown origin. SCP-3959-1 was in transport to Site-19 from a temporary storage container several kilometers outside of Site-01 during SCP-3959's first containment breach. SCP-3959 reportedly entered the vehicle via the radio and eventually came in contact with SCP-3959-1. This was not detected until █ hours later, where it was removed via contact with SCP-████ (Now Neutralized). SCP-3959-1 was then transported to what is now Provisional Site-██
SCP-3959-1 contains a complete history of the human race and references events that are unrecorded until its acquisition. In addition, subsequent readings have revealed the addition of new pages in accordance to modern events. As of ██/██/████, the first 248 pages are completely redacted.
The progress of SCP-3959's consumption of SCP-3959-1 has currently halted at the year ████, referencing the events of ████████ ████ and █████ ████ ████████.
At the current rate, it is projected that SCP-3959 can completely overtake SCP-3959-1 within ██ hours. Doing so would most likely result in an EK-Class Consciousness Collapse Event and/or a CK-Class Reality Restructuring Event.
Despite all security procedures involved, containment breach is imminent, as SCP-3959 is capable of infesting a wide variety of hosts, including but not limited to humans. Those who SCP-3959 prefers to occupy are usually individuals with acute eidetic memory, but it has been shown to choose random individuals with seemingly no preference. When infesting a human, SCP-3959 will feed on long term memories before short term, replicating symptoms of Alzheimer's over a period of several hours. Most do not notice any sort of change during this period, aside from light confusion.
Incident Report 3959-1A:
On ██/██/████, an attempt was made to terminate SCP-3959 via an unknown means. Knowledge of the termination attempt, the location of the test, and all involved were lost. In a later inventory check of Site-██, it was found that a single mirror was missing from Room 311 in sublevel 4. Correlation between the two is considered speculative at this point.
