The Krebbs on Security blog on 22nd March reported that Eric Eoin Marques was arrested in Ireland in 2013 on a US warrant and has been held in custody ever since. Now Ireland’s Supreme Court cleared the way for Marques to be extradited to the US. He allegedly ran sites on the Dark Web as Freedom Hosting. Sites could only be accessed using the Tor Browser Bundle, which is built on the Firefox Web browser.
