Item #: SCP-XXXX

Object Class: Euclid

Containment Procedures: Foundation Webcrawler WC-7429 "NotATF" will monitor popular 3D printing forums, technology websites, university forums and social media for any reference or traces of SCP-XXXX or SCP-XXXX-1 instances. Upon discovery, MTF Omicron-12 "Second Amenders" are to be scrambled for deployment to the target location.

Events affecting 3D printing devices are to be contained in situ by MTF Omicron-12, where the primary effort is containment of SCP-XXXX-1 instances, secondary objective is to minimise civilian casualties. Foundation disinformation assets working from Site-56 are to work to attribute civilian use of SCP-XXXX-1 to mundane causes.

SCP-XXXX-1 instances are to be stored in secure containment lockers at Site-56, with access limited to Researchers assigned to SCP-XXXX.

Revision 16/07/201█: Spare assets from Site-56 are to attempt to track PoI-XXXX with the assistance of Webcrawler-7249, containment of PoI-XXXX is to be considered an Alpha-Level priority.

Description: SCP-XXXX refers to a virus that affects 3D printing devices which, upon breaching a computer successfully, will corrupt any files pertaining to 3D printing schematics (mostly .amf, .stl and .vrml file formats). The files will become schematics for one of a number of small arms, all of which are anomalous to some extent and are designated collectively as SCP-XXXX-1, these files cannot be viewed prior to printing however, and will fail to load any preview or data for the corrupted file.

SCP-XXXX-1 instances are created using the materials the printer would normally use, and appear to operate as functional weapons despite the products used to create them. Efforts to create SCP-XXXX-1 instances without the virus have been unsuccessful, and SCP-XXXX has yet to create any instances that are identical.

Examples of effects demonstrated by SCP-XXXX instances can be found below, although is not an exhaustive list:

Appearance Effect Recovery
Beretta .45 handgun Fires no projectile, however target perceives pain from a GSW as if from a weapon of similar calibre. Recovered from Berlin University Engineering Department
AK-74 Weapon penetrates an average of 3km through any material. Recovered from DoD building 3481, Alaska.
SA80 A2 Weapons adjusts aim autonomously based on user's intent, vastly increasing accuracy. Recovered from UK MOD R&D facility in Skye, Scotland.
MP-5 User becomes incredibly proficient at close-quarters combat while holding the instance (See Incident Log XXXX-01). Recovered from a private residence in Lincoln, Nebraska.
M40A3 Rifle requires no ammunition and is not directly observable to anyone except the user, although recording equipment can still capture images. Recovered from SSgt Firth, U.S. Army Intelligence and Security Command, after his deployment to Iraq in 2005
Mossberg 500 When weapon is directed at someone they enter a highly suggestible state towards the user, obeying the latter's commands entirely. Recovered from a warehouse in downtown New York after reports of a number of robbings in broad daylight.
RPG-7 Rocket impacts and explosions create zero recordable sound, including any environmental stress created. [DATA REDACTED]

Foundation IT analysts were able to track the main distribution source of SCP-XXXX online; a forum on the site ████. The posters identified themselves as "The Anarchaos Society" (Designated GoI-XXXX) and frequently mentioned spreading SCP-XXXX via hacking, public 3D printers, university department access and insertion of USBs containing SCP-XXXX into various systems.

The forum has given valuable foresight into future events spreading SCP-XXXX, and as such MTF Omicron-12 has been successful in containing the majority of SCP-XXXX-1 instances after their creation.
