First time accepted submitter elysiuan writes "The founder of Freedom Hosting has been arrested in Ireland and is awaiting extradition to USA. In a crackdown the FBI claims to be about hunting down pedophiles, half of the onion sites in the TOR network have been compromised, including the e-mail counterpart of TOR deep web, TORmail. The FBI has also embedded a 0-day Javascript attack against Firefox 17 on Freedom Hosting's server. It appears to install a tracking cookie and a payload that phones home to the FBI when the victim resumes non-TOR browsing. Interesting implications for The Silk Road and the value of Bitcoin stemming from this. The attack relies on two extremely unsafe practices when using TOR: Enabled Javascript, and using the same browser for TOR and non-TOR browsing. Any users accessing a Freedom Hosting hosted site since 8/2 with javascript enabled are potentially compromised."
