One of the largest online collections belonging to the self-styled Islamic State group has been discovered online by researchers.
The digital library contains more than 90,000 pieces of content and has 10,000 unique visitors per month.
Experts say the bookstore is being used to spread extremist content online. But crashing it is difficult as the data is not stored in one place only.
And despite the fact that counterterrorism authorities in Britain and the US have been warned about this bookstore, it continues to grow.
The revelation came after the death of ISIS leader Abu Bakr al-Baghdadi in October 2019. At that time most of the posts on social media in support of this terrorist organization contained a short link.
Researchers discovered documents and videos in 9 different languages. They contained details of the attacks in Manchester on 22 May 2017, in London on 7 July 2005 and the US on 11 September 2001.
The library is also known as Caliphate Cache. Data is disseminated through a decentralized system and not a single computer server. This makes it difficult to crash and take it offline.
Materials are added to social media and disseminated through robotic accounts.
