Users running the latest version of the Tor Browser Bundle or Firefox are not at risk from the attack. The vulnerability has been fixed in both Firefox 22 and ESR-17. That exploit loaded malware that infected users’ computers. The Tor Browser Bundle is based on Firefox ESR-17.Īpparently the attack code configured Freedom Hosting’s servers so that they injected a JavaScript exploit in the Web pages delivered to users. Mozilla announced the MFSA 2013-53 vulnerability on Sunday. That saves businesses considerable effort, because Mozilla unleashes a new version of Firefox every six weeks. An ESR brings new features to the browser build without requiring users to update to the latest version. The latter is in Extended Support Release. The attack was launched through a vulnerability in Firefox 22 and Firefox version 17.0.7. The FBI declined to comment for this story because the investigation is ongoing.

However, some Tor hidden services users reportedly complained that their copies of Tor Browser, a modified version of Firefox, had been infected with malicious JavaScript that de-anonymized them by default.

“It was the end points, and there are any number of exploits you can run against a Web server.” “It wasn’t the Tor network itself that was compromised,” Pete Ashdown, founder and CEO of Utah ISP XMission, told TechNewsWorld. The Tor project, an open network that promises anonymity to users, has denied any connection with Marques. He is being held in an Irish jail pending the determination of the extradition request Marques, whom the FBI alleges was running a huge child porn network on Freedom Hosting using Tor hidden services, has dual Irish and U.S. The FBI is seeking to extradite Freedom Hosting’s owner, Eric Eoin Marques, to the United States on a Maryland warrant, according to the Irish Independent. Ireland-based Freedom Hosting, which hosted several servers on the Tor Project’s hidden network, has been taken down through a vulnerability in the Firefox browser - and the FBI is widely suspected of being the attacker.
