This type of news, found in traditional news, social media  or fake news websiteshas no basis in fact, but is presented as being factually accurate. These stories are not only found in politics, but also in areas like vaccination, stock values and nutrition. Guy Campanile, also a 60 Minutes producer said, "What we are talking about are stories that are fabricated out of thin air. By most measures, deliberately, and by any definition, that's a lie.
On the one hand, we introduce two passive attacks that demonstrate an identity mapping attack and a method to perform website fingerprinting. On the other hand, we present an active cryptographic attack called aLTEr attack that allows an attacker to redirect network connections by performing DNS spoofing due to a specification flaw in the LTE standard.
In the following, we provide an overview of the website fingerprinting and aLTE attack, and explain how we conducted them in our lab setup. Consequences How practical are the attacks? We conducted the attacks in an experimental setup in our lab that depends on special hardware and a controlled environment.
These requirements are, at the moment, hard to meet in real LTE networks. However, with some engineering effort, our attacks can also be performed in the wild. We present three individual attacks: For mapping user identities in the radio cell see paper for detailsfor learning which websites a user accessedand for performing an alteration attack e.
Can this happen to me? In theory yes, but expect the effort to be high. The most likely victims of such targeted attacks in practice are Fake technical research paper of special interest e. Who knows about the attacks? In general, there are two types of traffic: Control traffic organizes how the user traffic is sent and received, whereas the user traffic is the actual payload, e.
In our analysis, we focus entirely on the second layer layer two of the LTE specification.

This data link layer lies on top of the physical channel, which maintains the wireless transmission of information between the users and the network. Layer two organizes how multiple users can access the resources of the network, helps to correct transmission errors, and protects data through encryption.
Mutual authentication means that the network and the phone can verify the identity of the partner, respectively. In the following communication, the derived key is used to encrypt the control and user traffic. Furthermore, the control traffic is integrity protected, which means that the attacker is not able to manipulate the traffic during the transmission.
Despite these security mechanisms, we found passive and active attacks that allow to observe which websites Bob accessed and even to redirect him to a fake website. Passive Attacks What are Passive Attacks?
In a passive attack, the adversary does not interfere with the network, but only eavesdrops on a connection. The eavesdropper Eve accomplishes this by deploying a sniffing device close to Bob.
As a result, she has access to all information that Bob sends to the network and receives in response, e. The data Link Layer protects transmissions through encryption.
Nevertheless, an attacker can still obtain meta-information about the communication process e. Website Fingerprinting Meta-information on the data link layer leak information about the consumption of data per time unit. For example, if Bob watches a video, he uses more traffic compared to when he accesses a simple website.
As a preparation step of the attack, Eve records popular websites and their layer two patterns. During the attack, she eavesdrops the meta-information and looks for similar patterns.
In case she finds a match, she knows which website the victim visited -- with a certain probability. Experiments and Results We conducted a website fingerprinting attack in our lab setup of an LTE network and tested different devices on a selection of the 50 most popular websites on the Internet.
We use this experimental evaluation to demonstrate the general feasibility of website fingerprinting on encryption data link layer traffic in LTE.
Our results indicate that such attacks, in fact, are possible: In future experiments, we plan to conduct the same experiments within a commercial network, which complicates the attack due to background noise and uncontrolled network dynamics. In our case, the adversary does both and intercepts all transmissions between Bob and the network.
Thus, Bob perceives the adversary as his usual network provider and connects to the simulation device.Consequences. How practical are the attacks?
