The FBI are known for their digital prowess, although they may require some help when it comes to breaking into an iPhone. One of their most recent successes was the tracking of people using the Tor network, but after a judge ruled that the defendants representatives needed to know how he was identified the FBI has declined to say how they tracked people across the Tor network.
The ruling was provided by the Judge overlooking the case and was provided so that the defendants experts could check that the method used to identify the client was both within the FBI’s authority and also properly identified the client amongst the thousands of users of the Tor network.
The Tor network is a system (also known as the Onion Router) which people can use to hide their true identity by encrypting their traffic and bouncing it around the world in a series of steps. The network is also known for hiding a selection of “secret” websites that can only be accessed from within the network.
The FBI claim that they have already provided enough details for the defence to figure out if they went beyond their authority. FBI Agent Daniel Alfin, states in the court papers filed by the DOJ in the case, as saying “knowing how someone unlocked the front door provides no information about what that person did after entering the house”. While a valid argument, one would also argue that if someone breaks into your house, stealing something from your house and gaining access were both things you need to be made aware, not just one of the two.
