Though Tor is pretty much the gold standard for anonymizing your internet traffic, the system is slow and inefficient. The Tor Browser is optimized for security and privacy, unlike most other web browsers, which are optimized for speed and do not defend adequately against attacks such as browser fingerprinting. The Tor platform has been incorporated into applications such as Torpark, a browser based on Firefox that causes a computer’s IP address to appear to regularly change.The Tor network is typically accessed through the Tor Browser, which is derived from Firefox.

'We have never seen such an attack ‘in the wild,’ and we think it no more likely that this paper would make such an attack easier or more likely than it was a few years ago when another version of it was documented,' Nerad wrote. More than 46 percent of the time, the paths could be calculated, revealing the source of the traffic, the paper said.īut several attacks against Tor have been developed, wrote Shava Nerad, Tor’s executive director, on the project’s blog. Then the researchers used an algorithm to link the 'path' of a website request. They placed malicious servers within the network that were designed to draw a substantial portion of routing requests by misrepresenting their bandwidth capability. 'The RIAA and other organizations might use our techniques to link Web or torrent requests to their corresponding requesters.'įor the experiment, the researchers constructed their own isolated Tor network using 66 servers. 'For example, law enforcement officers might use our techniques to cheaply and realistically track online predators,' according to the paper. The researchers, who consulted Tor project officials during their work, wrote on their website that they still feel it’s the 'most secure and usable privacy-enhancing system available.' But the paper outlines the privacy concerns that could arise from using the techniques.
