The Federal Bureau of Investigation (FBI) seized the database of Tormail service for its investigation on cybercrime and illegal online hacking. The operation is linked to seizure of Freedom Hosting, the most popular Tor hidden service operator company. The FBI is collecting information to catch cyber criminals and hackers that used the Tor network to protect their anonymity, the problem is that Tor was also used by normal people that desire to be anonymous online for legitimate purposes. Tor Stinks project and many recent news on the spying activity discovered on Tor Traffic made by an unknown Russian entity suggest us that nothing is completely secure and that anonymity is hard to preserve.”]
