Archive of leaked Equation Group materials, released by a group calling themselves "Shadow Brokers" - they are seeking to sell additional material, which is a violation of Github terms, and led to the Github repository they created being disabled. As such, none of the communication from the leaking group is hosted here, and will not be included.
Per an article that quotes Kate Guarente, a Github employee:
"Per our Terms of Service (section A8), we do not allow the auction or sale of stolen property on GitHub. As such, we have removed the repository in question"
This is the reason that the only material posted here is the contents of the archive, not their requests for money for additional material.
While the source of this material is in question, it's value to the information security community is not. This data is extremely useful to those that defend against advanced attackers, by giving an opportunity to explore their methods. This provides an easy way to explore and search this material.
Yes, it is. There are many places that you can download the original archive - there is no chance that this data is just going to disappear, but providing it here is easier for me, and likely easier for other security researchers.
