Item #: SCP-XXYY
Object Class: Keter
Special Containment Procedures: The Foundation is controlling all the paranormal and urban legend forums where potential victims of SCP-XXYY may be found. Any mention of a mystery user of the Deep Web giving links to websites about urban legends, and any incidents resembling haunting, that started after visiting those websites, are to be investigated immediately. People targeted by SCP-XXYY are to be given all necessary information and assistance to protect them from danger. Websites or accounts matching the pattern used by the entity are to be reported right away as malware distributors, so that administrators would remove them immediately.
In the meantime, research is ongoing to find an effective method of catching and containing SCP-XXYY. Because of demonic nature of the entity, Vatican authorities offered their help in this task.
Description: SCP-XXYY is rather non-corporeal entity whose appearance is currently unknown, possibly demonic in nature, hostile towards humans, exhibiting very aggressive behavior and using the Internet to find people, gain access to their houses, haunt it and later abduct the victims. It is currently unknown what happens to people who have already disappeared.
SCP-XXYY use urban legends to lure people, by contacting and making them enter the website made by the entity, always located in the so-called 'Deep Web', through a search engine similar to those usually used to enter there, but with a completely different name and overall design. The website always contains a lot of normally unknown information about a certain urban legend, often the evidence that is supposed to show that the legend is true. SCP-XXYY username is always connected with the legend that the targeted person is highly interested in. The general pattern is: the_[urban legend key-word]_truth; this name is found both in forum accounts, the e-mail address from which SCP-XXYY sends instructions to find the user on the Deep Web, along with the file to install the search engine, as well as in the Deep Web chat rooms, where the targeted person contacts SCP-XXYY and receives a link.
Anyone who installs a search engine sent by SCP-XXYY and enters the given website will begin experiencing strange events from 5 to 10 minutes afterwards. The events match those typically described as signs of being haunted by some invisible being: mainly strange noises, especially at night; shadows walking around the apartment; moving objects; lights in rooms turning off by themselves, etc. Typically, these events are most severe in the room where the computer was located when the person entered the website made by SCP-XXYY. Experiencing these events, most victims choose not to use the search engine to visit the website but regardless of that, the events will intensify with time, so that finally an inhuman roars can be heard in the selected room, along with sounds suggesting the demolition and scratching the walls, as if a wild animal was locked in there. After about 10 days the chosen victim mysteriously disappears. However, if the person keeps on visiting the website, the only difference is that the disappearance will happen faster, even after 5 days since the first exposure.
The search engine can be simply deleted from the computer, and this appears to cause SCP-XXYY to lose access to the victim and thus save the targeted person. However, the search engine may reappear on the computer after some time, and in such a scenario its very important to not open it and certainly not try to enter the website again, as this may cause a recurrence of events. Prayer seems to help in weakening them, but does not completely eliminate the danger. As for exorcisms intended to clear the apartment of evil forces, they only help if are performed by an experienced exorcist and usually must be carried out repeatedly, until all traces of SCP-XXYY's activity disappear. This seem to confirm the entity's demonic nature.
Addendum XXYY-001: Existence of SCP-XXYY has been discovered at the beginning of 2020, when one of the Foundation's agents was randomly checking out forum about urban legends and found posts warning about Deep Web user who contacts people, offering unknown information about a given urban legend. It also said that lot of people who came across this person and visited a website that he gave them link to, afterwards noticed strange events in their apartments, similar to being haunted by ghosts, and the hired medium always sensed a "demonic presence", therefore getting rid of it required an exorcist intervention, which helped affter at least 3 sessions. In addition, when agent investigated further, he found many mysterious disappearances with a similar sequence of events, leading to the discovery of SCP-XXYY.
Addendum XXYY-002: Since SCP-XXYY pose a serious threat to humans, finding affected people and the accounts or websites about urban legends made by the entity, are currently one of the most important tasks. Since SCP-XXYY is very likely demonic in nature, and religious practices seem to undermine its activities, therefore only deeply religious researchers are assigned to it and, while searching for the entity activities, are advised to be extremely careful. Also, as an additional safety measure, they are under the non-stop supervision of an experienced exorcist, sent from the Vatican, whose authorities are also very much interested in capturing this entity.
Addendum XXYY-003: One of the researchers assigned to SCP-XXYY, Dr. █████████, asked for permission to conduct a series of experiments with D-Class personel, which would give the opportunity to gather more information about SCP-XXYY, and maybe even facilitate in developing a way to catch and contain the entity.
