The "How" of the onion-router slicing has a few possible avenues of inquiry. The Tor Project doesn't know how the anonymizing service was foiled, but it has possibly relevant information it shared on Sunday.Īs Tor project executive director Andrew Lewman wrote, in the previous few days, The Tor Project had received reports that several Tor relays had been seized by government officials (The Tor Project doesn't know how or why) - specifically, three systems (used to run Tor exit nodes) that blinked out of existence. It also includes activists and others for whom it's crucial to protect privacy so as to ensure safety from persecution, be it from oppressive regimes or dangerous stalkers. The Tor user base doesn't just include bad guys - the drug lords, drug buyers, illicit arms traffickers, money launderers and child-abuse image swappers.

That's all that law enforcement was willing to share about how it managed to slice through the layers of the Tor network, which is designed to mask users' identity by means of software that routes encrypted browsing traffic through a network of worldwide servers.

Based on posts made to the SR2 Forum, complaining of service outages at the time the imaging was conducted, I know that once the Silk Road 2.0 server was taken offline for imaging, the Silk Road 2.0 website went offline as well, thus confirming that the server was used to host the Silk Road 2.0 website. On or about May 30, 2014, law enforcement personnel from that country imaged the Silk Road 2.0 Server and conducted a forensic analysis of it. In or about May 2014, the FBI identified a server located in a foreign country that was believed to be hosting the Silk Road 2.0 website at the time (the “Silk Road 2.0 Server”). When the administrator of Silk Road 2.0 was busted last week, the agent who penned his indictment was tight-lipped about how, exactly, the FBI got its hands on the supposedly hidden server the dark net market was using, saying that the Bureau simply "identified the server located in a foreign country," and that law enforcement managed to image it sometime around.

While ‘dark websites’ that require encryption software continue to be used across Australia the anonymity of such activities seems to be less and less certain. This is not the first scare that Tor users have had, earlier in the year the heartbleed bug not only compromised a majority of internet sites but also rendered the anonymity of Tor users vulnerable. Tor responded to the hack in a recent blog post saying that traffic correlation attacks “are not a new arena” and that they have already worked to implement security measures. “A powerful, yet non-global adversary could use traffic analysis methods … to determine the various relays participating in a Tor circuit,” he said. The de-cloaking method involves introducing disturbances into the highly regulated environs of onion router protocols and then exploiting the Cisco netflow tool built into its routers to analyse router data.ĭr Chakravarty has said that it’s not even necessary to be a highly resourced in order carry out such a traffic analysis attack. In research conducted between 20, Professor Sambuddho Chakravarty published a number of papers that claimed a 100 per cent ‘de-cloaking’ success rate under laboratory conditions and 81.4 per cent in the actual Tor network. However, the anonymity that Tor is premised on may not be so ironclad. The software is the most popular of its kind and has been embraced by a growing number Australians seeking to keep their internet activities private.

Tor is a free encryption software program known as an onion router that provides anonymity to the user by running internet activity through a worldwide network of volunteer servers. Research by a computer science professor formerly of Columbia University has shown that 81 per cent of Tor users can be ‘de-anonymised.’
