New Tor Browser Bundles

The anonymity provided by Tor seems to have been shaken by the team of researchers led by Eric Filiol, director of research at the laboratory and ESIEA Cryptology and Virology operational in France. French scientists say they have managed "to break both the encryption and anonymization, [...] which allows us to access all the information clear."
This week at a conference at ESIEA (http://www.esiea.fr/), Eric Filiol said to have reached an inventory of all machines, 5827 nodes in total, connected to the Tor network. A total of 9039 IP addresses were identified, one more than the total number of machines but due to the presence of dynamic IP addresses.
In this study, French researchers have discovered hidden nodes, the "Tor Bridges", "not listed in the source code. Only the foundation routers Tor knows these hidden" explained the expert computer. Using an algorithm of their own, the research team identified 181 hidden nodes.
With this, the researchers were then able to analyze the nature and machine safety. It showed that 41.4% of them run on Windows and that about 30% of all nodes are vulnerable. These vulnerabilities are clearly sufficient "to infect and they can be easily obtain system privileges" continued Eric Filiol.
Taking control of machines can then address the encryption keys used to protect communications. Of the three layers of protection, two were diminished and the third was pierced by a statistical method. From there, the exchanges between the different nodes can be deciphered without difficulty. "Cryptography based in TOR is weak" said the laboratory director.
Once the data protection transported is raised, the next step is to channel traffic through the infected routers. This method can be done with using the "packet spinning force," a technique that forces the machine to cycle in order to run the packages in circles. "It does not cause denial of service, just a micro-congestion," he added. (See:
