NOTICE FROM O5-██. The current 'public' documentation of SCP-XXXX has been intentionally fabricated in an attempt to suppress any knowledge of the anomaly. Neither the microprocessor, Incident XXXX-Delta, nor the apple story planted by the current iteration of the documentation, possess any real anomalous properties. This document is only for the eyes of personnel involved in 'Project Prime/XXXX', and any unauthorized access will be considered an emergency containment breach, and result in immediate termination. Document XXXX-Theta is the real documentation of SCP-XXXX.

Recreated Instance of SCP-XXXX-Q, using decoy information to avoid anomalous effect.

Item #: SCP-XXXX

Object Class: Keter

Special Containment Procedures: Foundation supercomputer "Aurum-X" has been built with the sole purpose of containing instances of SCP-XXXX-A through -S. Due to the nature of SCP-XXXX, containment of the object has been deemed impossible.

All partnered and Foundation-owned radio listening stations are to always be monitoring the frequency of ████.██hz. Should the pattern deviate from the standard white noise heard on the frequency, data is to be decrypted to confirm the infection of a subject with SCP-XXXX, and the subsequent location of said subject.

Upon locating new instances of any new media created by SCP-XXXX (deemed SCP-XXXX-A through -S), "Aurum-X" will attempt to suppress any possible publicity these products may receive. If any mammalian creatures, especially humans, are suspected to have been exposed, MTF Aurum-Delta-X ("Trained Professionals") are to be immediately dispatched to terminate any exposed subjects via any lethal force necessary, including nuclear strikes if requested. Failure to carry out termination within a 2 hour period will be considered a breach of containment. Once this mark is reached, all foundation sites are to immediately activate shutdown state, and all available MTF's are to be dispatched to the SCP-XXXX-1 instance.

Description: SCP-XXXX is the designation of an unknown entity or artificial intelligence system that is capable of infecting human and mammalian entities via the viewing of materials it produces. SCP-XXXX is able to empress its anomalous properties upon these subjects in the form of various complex and/or subtle infohazards and cognitohazards placed in various forms of media that are not fully understood, these are designated SCP-XXXX-A through -S (see addendum for more information).

Upon viewing an instance of SCP-XXXX, subjects will become immediately infected. They are not required to to acknowledge or understand the contents of the media they are viewing for the infection to be successful. Roughly 2 hours after infection, the anomalous properties of SCP-XXXX's infection (hereafter referred to as SCP-XXXX-1) manifest. The infection escalates over the course of 16 hours from point of initial infection. The 16 hour mark has not yet been reached due to containment protocols in testing, and the effects are only projected. Should a subject reach the 16 hour mark, an almost certain XK-Class End of the World Scenario will occur. Should the 16 hour mark be reached, the O5 council and any Level 4 personnel within range are to evacuate to SCP-████, when it is to be activated immediately, without question.

Stages of Infection:

Stage 1

Time: (Point of Infection)

Duration: 2 Hours

Symptoms: None. Subject's exact longitude and latitude coordinates are broadcast on the frequency of ████.██hz, along with a series of strings composed of indecipherable Latin, with every other word being 'apple'. Capitalization varies per instance.

Note that regardless of time from infection, no successful means of expunging SCP-XXXX-1 from a host have been found. The host must be terminated, and the remains will be subsequently incinerated, launched into space on a Foundation satellite, and detonated by an on-board nuclear warhead. Any personnel that challenge this practice, or dismiss it as "excessive" are to refer to 'Addendum Prime.'

Stage 2

Time: 2 Hours

Duration: 2 Hours

Symptoms: Subject's bodily functions immediately cease expected functions. Subject will still be able to vocalize, though in a slurred fashion. Throughout the 2 hour period, subject's speech will gradually become less comprehensible, until SCP-XXXX-1 disables all bodily function. Subject is immediately considered deceased. //Note that after this point, any interaction of organic material with the subject results in immediate dematerialization.

Stage 3

Time: 4 Hours

Duration: 4 Hours

Symptoms: After SCP-XXXX-1 assumes control of the host, all bodily fluids (with a few exceptions) and wastes will be slowly, but violently expelled from the corpse. Spinal fluid and bone marrow are apparently unaffected. Once all fluids have been drained, the corpse will reanimate. At this point in time, [DATA REDACTED]. SCP-XXXX-1 will now stand upright and calmly tear open its chest cavity, removing all internal organs and attached systems with the exception of the left lung and brain. The nervous system apparently remains inside of the host, but it is unknown whether any function persists. Once this process is finished, the corpse will collapse onto the ground and remain dormant until the next stage begins.

Stage 4

Time: 8 Hours

Duration: 8 Hours

Symptoms: Corpse will reanimate itself once more, and stand up. After roughly 8 minutes of standing with no apparent movement, the corpse will dematerialize in a domino fashion from the toes to head, before [DATA EXPUNGED], this event takes roughly 120 seconds. Once there is no apparent trace of the subject, an entity made out of copper (hereafter referred to as SCP-XXXX-2) will manifest, taking the form of the previous test subject. SCP-XXXX-2 will manifest in the fetal position, hovering exactly 2 meters above the ground. As time passes (initially at the 30 minute mark), the subject will begin to attract any and all matter around it, before it apparently dematerializes. This attractive force grows exponentially over time, and has been responsible for numerous premature terminations of foundation personnel, and loss of equipment, earth, and civilians.

The only effective method in containing SCP-XXXX-2 is to fire canons of common table salt directly at the chest, upon which the subject will 'melt' and resolidify as solid elemental copper, with no anomalous properties. The closer that the act of neutralization is decided upon to the 16 hour mark is, the more salt is required to terminate SCP-XXXX-2. The reason as to why this method is effective is currently unknown.

Stage 5 (PROJECTED)

Time: 16 Hours

Duration: Unknown

Symptoms: Based upon the rate of which SCP-XXXX-2's attractive-destructive force increases, at the 16 hour mark it is projected to be completely unstoppable by any logical means, and SCP-XXXX-2's force will create an XK-Class End of the World Scenario, wherein within 16 hours, the entire earth itself will be dematerialized by SCP-XXXX-2. The upper limit of the force that powers SCP-XXXX-2 is not known, and should the activation of SCP-████ not entirely neutralize the threat, it is to be assumed that the events unfolding will end in a ZK-Class End of the World Scenario.

Addendum: SCP-XXXX was brought to the foundation's attention on ██/██/201█, when Junior Researcher G█████ ████████ entered stage 2 of the infection, and was terminated as a result of the unfolding events. ████████ had previously viewed an instance of SCP-XXXX-A that had been anomalously produced by an on-site 3D printer.

SCP-XXXX events have no apparent pattern. Luckily, the vectors for infection appear to target very obscure media and are never discovered by civilians, however, the power of SCP-XXXX is not fully understood, and a much more catastrophic scenario could unfold. For this reason, on ██/██/201█, the foundation built "Aurum-X" to search for and destroy any digital manifestations of SCP-XXXX products.

Since its original discovery, SCP-XXXX has been responsible for the casualties of ██,███ civilians, ███ Foundation personnel, and has caused upwards of $██,███,███ in damages to property and possessions. SCP-XXXX is also responsible for [DATA EXPUNGED].

Infection Instances of SCP-XXXX

Designation (SCP-XXXX-X): A

Medium of Instance: Physical

Object Description: Red 3D-printed apples with varying Latin inscriptions carved into them.

Additional Notes: There has never been any evidence of the printers they are found in having been used prior to the manifestation of SCP-XXXX-A instances.

Designation (SCP-XXXX-X): B

Medium of Instance: Digital

Object Description: A picture of an apple. Instances have been exclusively found on the domain ████.co.uk, and appear to have been run through an algorithm similar to G█████ D███████.

[DATA EXPUNGED]

Designation (SCP-XXXX-X): G

Medium of Instance: Physical

Object Description: A postcard that manifests in the mailbox of the intended subject. The page consists of nothing but 'winky faces' and a crudely drawn apple. Postcard is found in a standard white envelope, with the return address listed as █████ Inc. headquarters.

Additional Notes: Only two instances of SCP-XXXX-C have ever been discovered, both intended subjects were former █████ Inc. employees. Note: No actual link between █████ Inc. and SCP-XXXX has been discovered.

[DATA EXPUNGED]

Designation (SCP-XXXX-X): M

Medium of Instance: Physical

Object Description: A 3D-printed apple, identical to A instances. However, testing has proven that though the apples appear to be printed with plastic, they are actually regular organic apples.

[DATA EXPUNGED]

Designation (SCP-XXXX-X): Q

Medium of Instance: Digital

Object Description: QR codes consisting of apparently random strings of characters, with the word "apple" being the only decipherable decryption of the strings.

[DATA EXPUNGED]

As of ██/██/20██, it was established unanimously that no study is to be conducted of SCP-XXXX or its instances. Any information regarding SCP-XXXX should only be presented in the form of the current documentation, or as a method of finding ways to neutralize the anomaly. Neutralization of SCP-XXXX is considered a Class-T priority.
