Researchers Institute of Strategic Dialogue (ISD), discovered a huge collection of content on the internet, which belongs to the self-proclaimed Islamic State.
It is a set of propaganda content, with more than 90.000 entries and has about 10.000 visitors a month.
Its purpose is to promote extremist content on the internet and despite the efforts of the authorities, both in America as well as in United Kingdom, is difficult to treat, since the data are stored in many different places.
The material includes details of terrorist attacks, including those at Manchester Arena on 22 May 2017, London on 7 July 2005 and the US on 11 September 2001.
You can find everything you need to know to design and build one attack", Said the deputy director of ISD, Moustafa Ayad, who discovered the file.
"Things that teach you how to become a better terrorist."
ISD named the collection Caliphate Cache.
As the researchers found, the data is distributed by a decentralized system and not by someone server. Anyone is able to share content on the internet through servers based on different sites.
One of the methods used by the Islamic State to disseminate its content is hijacking accounts of famous people. One such case was infringement of a Justin Bieber fan account, which was used to view material from the Caliphate Cache collection.
In addition to terrorist acts, the material includes the Islamic State's philosophy on lifestyle. The people who seem to be most interested in the content are from the Arab states and mainly between the ages of 18 and 24.
As ISD has discovered, Caliphate Cache is not the only collection of extremist content on the internet.
Authorities are trying to locate and download content related to terrorism, but this is an ever-increasing threat that is sweeping the internet.
