Current image medium used in containment of SCP-XXXX. Note: Image has been edited by entity.
Item #: SCP-XXXX
Object Class: Safe Currently uncontained
Special Containment Procedures: Entity is to be stored on a standard Foundation office PC that has attached one (1) monitor, one (1) computer mouse, and one (1) computer keyboard, for the purposes of testing. The PC is to be shutdown outside of testing.
The PC is to be located in a standard Site-15 safe-class medium-size containment chamber. The PC is not to be connected to any network, and no storage media is (or any peripherals not described above) are to be connected to the PC. All peripherals removed from the PC must be destroyed by furnace, via the standard Site-15 immolation route. Testing requires Level-03 approval.
Entity is currently not contained since Incident XXXX-02. Recontainment of entity is currently tasked to MTF Mu-4 ("Debuggers").
Description: SCP-XXXX is an electronic entity that can move itself between machines that are connected on a network. Whilst in a machine, SCP-XXXX "infects" either a single image or single video medium. The entity has not shown the ability to infect text or other media. SCP-XXXX is also able to move itself onto portable storage devices, aiding in its containment. Only one copy of SCP-XXXX may exist at any time, however when the entity moves between devices, and thus changes its infection medium, the previous infection medium is left behind as "waste".
The "waste" media left behind by SCP-XXXX are edited slightly from their original and exhibit medium-strength cognitohazardous properties. These cognitohazards can be inoculated against by standard cognitohazard inoculation, allowing for viewing of the waste media by personnel with cognitohazard training during containment operations.
SCP-XXXX appears to be drawn to prime numbers. When given a choice between infection media, the entity will choose the one that displays a prime number or multiple prime numbers over other media. The prime number must be displayed in Hindu-Arabic numerals.
Initial Containment: The existence of SCP-XXXX on the Foundation intranet was first identified by scanning software "COG-68", which scans all Foundation articles and databases in search of cognitohazards. Due to its sudden appearance on the Foundation intranet, and not being identified elsewhere, it is likely that the entity was placed on the Foundation intranet by a hostile party specifically to attack the Foundation.
After studying patterns in how the entity spread, its preference to media displaying prime numbers was noticed. A blank USB flash drive was loaded with a single image containing 30 10-digit prime numbers, and connected to the most recently infected machine. After 20 seconds, the flash drive was removed.
The image medium on the infected machine was scanned and confirmed to now be cognitohazardous. A day later "COG-68" began its scan again and identified no new unexpected cognitohazards in the database, suggesting that SCP-XXXX had infected the flash drive and was no longer infecting the Foundation intranet. The flash drive was connected to a computer in Site-15 with no network access. The computer was running a standard new copy of SCP-OS, and contained a containment medium image as seen above. After 20 seconds, the USB was removed and tested on another standalone version of "COG-68". The image on the USB flash device was identified as cognitohazardous, suggesting that the entity had left the flash device and thus moved onto the containment machine. The flash device was immolated in the Site-15 furnace.
Incident XXXX-02: On 16th December 2023, "COG-68" alerted staff to new unexpected cognitohazardous media on the Foundation intranet. During a check of all containment machines required after such an event, the containment image used for SCP-XXXX was found to now be cognitohazardous. Further, the machine's log recorded an unauthorized insertion of a USB flash device shortly before COG-68's alert. An investigation is ongoing. The now cognitohazardous image is viewable at the top of this page.
