Note that as a policy, unencrypted one-to-one conversations are not allowed and your messages will not be transmitted if the person you are talking with does not have an OTR-enabled client.On all platforms, Tor Messenger sets the profile folder for Firefox/Instantbird to the installation directory. On OS X, copy the Tor Messenger application from the disk image to your local disk before running it.On Linux, extract the bundle(s) and then run.There have been three previous alpha releases to the mailing lists that have already helped smooth out some of the rougher edges. Today we are releasing a beta version with which we hope to gain both usability and security related feedback. The main feature it lacked was OTR support, which we have implemented and hope to upstream to the main Instantbird repository for the benefit of all Instantbird (and Thunderbird) users. It also has an active and vibrant software developer community that has been very responsive and understanding of our needs. Instantbird was the pragmatic choice - its transport protocols are written in a memory-safe language (JavaScript) it has a graphical user interface and already supports many natural languages and it's a XUL application, which means we can leverage both the code (Tor Launcher) and in-house expertise that the Tor Project has developed working on Tor Browser with Firefox. We considered a number of messaging clients: Pidgin, Adam Langley's xmpp-client, and Instantbird. We are also excited about systems like Pond and Ricochet, which try to solve this problem, and would encourage you to look at their designs and use them too. However, your route to the server will be hidden because you are communicating over Tor. This has traditionally been in a client-server model, meaning that your metadata (specifically the relationships between contacts) can be logged by the server. Tor Messenger builds on the networks you are familiar with, so that you can continue communicating in a way your contacts are willing and able to do. It supports a wide variety of transport networks, including Jabber (XMPP), IRC, Google Talk, Facebook Chat, Twitter, Yahoo, and others enables Off-the-Record (OTR) Messaging automatically and has an easy-to-use graphical user interface localized into multiple languages. Tor Messenger is a cross-platform chat program that aims to be secure by default and sends all of its traffic over Tor. Today we are releasing a new, beta version of Tor Messenger, based on Instantbird, an instant messaging client developed in the Mozilla community. Please see the announcement for more information. Our proposed solution can be readily added to existing network monitoring infrastructures and includes among other things plausibility checks of location update trails, monitoring of device-specific round trip times and an offline detection scheme to detect cipher downgrade attacks, as commonly used by commercial IMSI Catchers.As of March 2018, Tor Messenger is no longer maintained and you should NOT use it. Hence, contrary to popular belief, network operators by default do not have a global view or their network. One of the major challenges from the operator’s point of view is that cellular networks were specifically designed to reduce global signaling traffic and to manage as many transactions regionally as possible. Moreover, we draw a comprehensive picture on current threats against mobile phone devices and networks, including 2G, 3G and 4G IMSI Catchers and present detection and mitigation strategies under the unique large-scale circumstances of a real European carrier. In this paper we are the first to present and discuss multiple detection capabilities from the network operator’s point of view, and evaluate them on a real-world cellular network in cooperation with an European mobile network operator with over four million subscribers. Multiple countermeasures have been proposed recently to detect such devices from the user’s point of view, but they are limited to the nearby vicinity of the user. They are readily available as commercial products as well as do-it-yourself projects running open-source software, and are obtained and used by law enforcement agencies and criminals alike. An IMSI Catcher, also known as Stingray or rogue cell, is a device that can be used to not only locate cellular phones, but also to intercept communication content like phone calls, SMS or data transmission unbeknown to the user.
