FBI has hacked world’s largest child pornography website ‘Playpen’ which was hosted in the ‘dark web’ or ‘deep web’. The site became operational in August, 2014 and allowed users to view and upload child pornography related material. The site gathered almost 215,000 members by end of 2015 and it had close to 11,000 hits every week.
FBI hacked the servers of Playpen in February, 2015 but did not shut the website down and instead monitored user behaviour and their IP addresses. As a result of this sting operation, 1,300 people have been arrested so far. FBI says some of the images found on that website were of the most extreme nature.
