One such moment occurred a few days ago when membership data from a Pro-Nazi site named Iron March was disclosed which included usernames, email addresses, private messages, forum management logs, multi-factor authentication logs and IP addresses of approximately 1000 members.
The benefits gained from this leak are immense. Firstly, as the members of such sites usually engage in hate speech and the planning of extremists/terrorist activities, this data would help authorities identify and stop those people.
Secondly, it helps us call out such hidden members of society reducing the threat of white supremacist ideas spreading across the internet. Finally, we have also gotten an understanding of the demographics of such members. This was done through an analysis of the data found by numerous entities which showed us that many of these members were an active part of the military or expressed a desire to join it in the future.
