A still image of SCP-3XXX-1

Item #: SCP-3XXX

Object Class: Euclid Keter

Special Containment Procedures: 1 (One) digital copy of SCP-3XXX is to be kept on a 10GB storage card in medium-hazard item vault-72C at Site-██. Under no circumstance will a live working copy of SCP-3XXX be introduced into the foundation's system.

Any and all testing that takes place on SCP-3XXX must be conducted in a level-1 testing vault. No windows or observational equipment shall be allowed on/in the room. During testing SCP-3XXX will be placed in a generic civilian laptop specially designed foundation laptop. At any time during testing, the device must be able to be remotely instantly destroyed. The device must not have access to any network. For transmission testing, a closed loop "intranet" can be used to simulate propagation.

All computers within the foundation must be installed with an upgraded hard drive that has proven to delay the infection of SCP-3XXX, refusal to install the new hard drive will result in the destruction of the device in question.

In the case of a widespread breach of SCP-3XXX within the foundation, procedure 1oD is to be activated, and all essential personnel are to be evacuated from the facility. It is approximated that if one instance of SCP-3XXX was introduced into the average population of a foundation facility, all devices within the facility would be infected with 8 minutes

Description: SCP-3XXX is an anomalous computer executable (.exe) with the file name, Techdom.exe. SCP-3XXX can appear on any computer system that meets these requirements.

  • The device must have access to the internet
  • The device must have a screen with a resolution of over 500x500 pptx.1
  • The device's display must have a refresh rate of over 24 Hz2

As of the creation of this document, there is no known operation that can prevent SCP-3XXX from infecting a computer, other than not meeting the requirements above.

SCP-3XXX Cannot be removed from a device once affected, only known solution to end the propagation of SCP-3XXX and/or to end display of SCP-3XXX-1 is complete destruction of any data storage unit on the device.

Once SCP-3XXX is installed on a device, it will propagate copies of itself onto other systems connected to the current device, this includes but is not limited to: Ethernet connection, wireless connection, online connection3.

Once SCP-3XXX has completed this first phase, it will display SCP-3XXX-1. SCP-3XXX-1 is a soundless series of images of certain nature including, images of static, images of doorways and multiple [DATA EXPUNGED]. SCP-3XXX-1 will loop until the device is turned off, it is noted that SCP-3XXX-1 will still be looping once the device is able to input data into the display. Furthermore, individually preventing the transmission of SCP-3XXX-1 to output screens requires the complete destruction of the originally connected device's storage. All screens originally connected to a device infected with SCP-3XXX will continue to produce SCP-3XXX-1 unless the above procedures are followed or the display is no longer capable of outputting images (Through physical destruction). Viewing SCP-3XXX-1 for more than 5 seconds has a memetic effect on the viewer. Those who have observed SCP-3XXX-1 for more than 5 seconds are to be designated SCP-3XXX-2.

Instances of SCP-3XXX-2 will instantaneously experience the memetic effect of SCP-3XXX-1. SCP-3XXX-2 subjects will experience, extreme aversion to all technological devices that meet the requirements of SCP-3XXX infection (including hosts of SCP-3XXX-1) and a feeling of doom/existential threat when within a 3-meter radius of any device. Due to all of the aftermentioned effects, SCP-3XXX-2 will want to separate itself from the source of SCP-3XXX-1 within a short amount of time. Subjects are seen to go into panicked states if they cannot complete this task (See testing of prolonged exposure to SCP-3XXX-1).

Administration of class A amnesties has proven effective on temporarily negating the effects of SCP-3XXX-1, for permanent removal of SCP-3XXX-1's memetic effects, see procedure 1010-Charlie.


On October 20, 20██ Foundation webcrawlers noted a post on an online forum containing a downloadable executable, of which contained several images flagged as "possibly Memetic". This was later identified as SCP-3XXX (See Incident 3XXX-I)
