Item #: SCP-670
Object Class: Euclid
Special Containment Procedures: SCP-670 is to be stored on a computer in a standard locked room. The computer is kept devoid of any elements allowing recording on physical support (such as, but not limited to: USB ports, CD burners or floppy drives). Unless an activation of SCP-670 is performed as part of an experiment, no cathode ray tube-based monitor should be connected to it. The room must be completely impenetrable to wireless communications, and must not contain any phone line or Internet outlet. No electronic support (up to and including full disk drives) may come into the room. Any attempts to enter with such a support or matching recording apparatus will result in the subject being reassigned to Keter-class SCP maintenance. Equipment which has been infected must be either magnetically wiped-out or destroyed.
The triggering command line is not to be transcribed on any support and is solely known to level ██ personnel. Lower-level personnel coming into contact with the command for research or any purposes are to be administrated a Class-A amnesiac afterward. Attempts to retain or transmit knowledge of the command line for non-approved research purposes shall be met with termination.
Description: SCP-670 is an apparently harmless computer virus able to infect both Macintosh- and Windows-based systems (no versions based on other operating systems are known). It is written in an unknown programming language and dissimulates itself by discreetly overwriting a number of dynamic-link libraries (DLLs) or little-used dependencies. The virus transmits itself easily (via a yet undiscovered method) over any Internet connection and is undetected by most antivirus software (those that detect it do not identify it, only noting file alterations). It will also infect any writeable support connected to an infected machine, and from this support, infect further machines.
The virus is normally dormant and does not affect the computer in any fashion unless a specific command line is executed as part of a file within the system. Some of the characters required to type the command are not part of any standard character sets, and as such the line cannot be typed on a normal keyboard. The command can be sent directly, such as over an Intranet or via separate hacking, in a file or email etc. It is made of a complex series of characters and [DATA EXPUNGED], resulting in a catastrophic failure of the cathode ray tube contained in the visual display unit (the VDU, a.k.a. the monitor), causing a violent explosion and sending shards of sharp glass, heated plastic and metallic pieces forward. Non-cathode ray based VDUs are unaffected, as are the other computer components (however, due to [DATA EXPUNGED], and inevitably leads to infection).
Addendum 01
A few incidents of the virus being activated outside laboratory settings (see Incident Reports 670-01 through ██) have led to massive disinfection attempts that have all failed, so that the primary containment measure is to restrict the trigger command rather than the virus itself, although preventing its spread within the SCP Intranet is seen as a major priority. It is suspected a significant portion of computers and device in the wild are contaminated. Tracking the triggering command in the wild has lead to the anomalous conclusion that [DATA EXPUNGED] and all data was [DATA EXPUNGED]. The possible existence of a [DATA EXPUNGED] in particular is worrisome.
Document 670-01
Dr. ████ has suggested the number involved in defining some of the character may be SCP-033. Request to pursue research in this direction is pending. Dr. ████████
Document 670-02 Log of Dr. ████████
Agent █████ died today after the power supply of his monitor exploded. He appears to have been in the process of hastily replacing his monitor with a flatscreen display.
