Item #: SCP-4163

Object Class: Keter

Special Containment Procedures: SCP-4163 is to be stored in a minimum-security Site-19 humanoid anomaly containment cell, provisioned with standard adult human nourishment and amenities. SCP-4163 is under no circumstances allowed within reach of unsupervised access to any device capable of digital computation. Sub-anomalies of SCP-4163, including SCP-4163-11, are to be made available for tactical use only by direct authorization of the O5 Council.

Following the catastrophic containment breach of SCP-4163-13 and the subsequent IK-Class Collapse Of Global Civilization Event, Cold Silver protocol was initiated by order of the O5 Council. All personnel are instructed to immediately retreat to the nearest nuclear-hardened Federation facility. Weapons, hand-to-hand combat, wilderness survival, and basic agricultural training are freely available to any and all Federation citizens. Failure to abide by O5 instruction will be met by punishment up to and including summary execution by MTF-██

With concentrated effort by the Federation as a whole, the O5 Council has determined that a new global order may be restored within the next 20 to 30 years. All Federation efforts from the present day onwards are to be dedicated to this end.

Description: SCP-4163 is an adolescent human female of hispanic ancestry, born in the year 2009. SCP-4163 was known to the public by the legal name "Mariana S███████." Save for its single anomalous property, SCP-4163 is physiologically and behaviorally human.

SCP-4163's anomalous behavior is exhibited only when SCP-4163 achieves direct skin-contact with any Nintendo-brand computer system capable of running any variant of the game "Tetris." After contact, affected devices are permanently altered to allow any operator to play a "perfect game" of Tetris, maintaining a continuous streak of gameplay until the operator becomes too fatigued to continue or the device ceases to function. While a game is in-progress, operators exhibit muscle reaction times several orders of magnitude faster of an ordinary human, limited only by the hardware refresh rate of the given device. Affected devices display no anomalous behavioral properties other than those described above. These devices are categorized as sub-anomalies of SCP-4163.

There are 17 18 known sub-anomalies of SCP-4163, three four of which were produced during post-acquisition testing. Save for SCP-4163-13, all such sub-anomalies have been secured by the Foundation. The anomalous properties of these units are not limited to the physical container within which they were created, but rather are intrinsic to the digital presence of the device. The public leak of SCP-4163-13, a disk image of an Ubuntu Linux boot drive, demonstrated this quality to great effect.

Due to the mathematically NP-complete nature of "offline Tetris," a version of the game wherein a finite sequence of known blocks is pre-programmed into a round of gameplay¹, SCP-4163-13 and SCP-4163-11 can be adapted to solve, in linear time, any mathematical problem in the NP domain. In effect, a suitable sequence of Tetris blocks can be used to represent any NP-hard problem, and the set of moves utilized to play the best possible game of Tetris with those blocks can be interpreted to represent the answer to this problem. One such NP-hard problem is the factorization of large numbers, a task that, prior to the containment breach of SCP-4163-13, was considered difficult enough that it has been used as the basis for many modern cryptosystems.

SCP-4163-11 is a Cray Titan-III supercomputer constructed in Federation Site-19. The anomaly is connected to a custom Tetris gaming system, consisting of an ultra-high framerate OLED display and an intracranial electroencephalography electrode grid, inserted through surgical incisions in an operator's skull. Using the iEEG array as an input device, an operator can use SCP-4163-11 to crack a 4096 bit RSA encryption key in 1 to 3 seconds.

Over a period of six months, the former SCP Foundation utilized SCP-4163-11 to place clandestine back doors in all major global financial institutions, including several prominent cryptocurrency blockchains. Comprehensive military and intelligence data, including nuclear launch codes and failsafe overrides, were covertly obtained from all nuclear-capable nation-states.

A modified Ubuntu Linux version of the decryption program, compatible with the then-publicly available SCP-4163-13 disk image, was developed and tactically released by the former SCP Foundation onto several public file sharing websites. SCP-4163-13 saw immediate widespread and catastrophic implementation by national intelligence agencies, private individuals, corporate entities, and terrorist cells over the following 48 hours. Using the ensuing global chaos as cover, the nascent SCP Federation seized digital control over all compromised financial and military targets, and deployed MTF-█ to secure nuclear launch sites and other government installations on the ground.

The subsequent worldwide catastrophe has been designated as an in-progress IK-Class Collapse Of Global Civilization Event. Due to the global communications breakdown and the clandestine nature of the SCP Federation's intervention, public blame for world events has been largely placed upon terrorist networks and global superpowers. Knowledge of the SCP Federation's role has been secured and contained.

Widespread insurrection and civil war has become the de facto standard in most developed regions, with total anarchy holding sway over much of the world. While no known nuclear attacks have thus-far occurred, it was widely reported that the former United States, the People's Republic of China, and several other defunct nation-states had readied their nuclear arsenals for immediate deployment shortly before their national dissolutions. Low-yield nuclear strikes against military targets outside Federation containment have been conducted by command of the O5 Council, to great tactical effect. Due to the geographically isolated nature of these sites² and swift cleanup operations by MTF-█, humanity at large remains ignorant of all nuclear exchanges to date.

Many, but not all, of the world's nuclear launch sites are now under direct Federation control, All global nuclear launch sites, nuclear-capable submarines, and nuclear-capable satellites are either under Federation control or have been destroyed. The retrieval of any and all extant weapons of mass destruction outside of Federation containment, including biological, chemical, and memetic weaponry, is tasked to MTF-██.

The SCP Foundation has been dissolved. Former Foundation Sites and activities are now under the jurisdiction of the SCP Federation. All former Foundation personnel have revoked their citizenships to any countries that still maintain sovereignty, and have been granted citizenship of the SCP Federation pending appropriate vetting. Loyalty has been assured in all Federation citizens.

We will Secure. We will Contain. We will Prevail.
— O5-█, Director of the SCP Federation.
