To learn more about what information is available to someone observing the different parts of a Tor circuit, see the interactive graphics at Tor FAQ: Can exit nodes eavesdrop on communications? Tor exit nodes have been used in the past to collect sensitive information from unencrypted connections.
Malicious exit nodes are regularly identified and removed from the Tor network. For an example, see Ars Technica: Security expert used Tor to collect government e-mail passwords. A powerful adversary, who could analyze the timing and shape of the traffic entering and exiting the Tor network, might be able to deanonymize Tor users.
These attacks are called end-to-end correlation attacks, because the attacker has to observe both ends of a Tor circuit at the same time. End-to-end correlation attacks have been studied in research papers, but we don't know of any actual use to deanonymize Tor users. Tails protects you from viruses and malware on your usual operating system.
This is because Tails runs independently from other operating systems. But your Tails might be corrupted if you install from a compromised operating system. To reduce that risk:. Always install Tails from a trusted operating system. For example, download Tails on a computer without viruses or clone Tails from a trusted friend. Do not use your Tails USB stick to transfer files to or from another operating system.
If you worry that your Tails might be corrupted, do a manual upgrade from a trusted operating system. We don't know of any virus able to infect a Tails installation, but one could be created in the future. Your computer might be compromised if its physical components have been altered. For example, if a keylogger has been physically installed on your computer, your passwords, personal information, and other data typed on your keyboard could be stored and accessed by someone else, even if you are using Tails.
Try to keep your computer in a safe location. Use a password manager to paste saved passwords. This way, you don't have to type passwords that might be visible to people or cameras near you. Use the Screen Keyboard , if you are using a public computer or worry that the computer might have a keylogger. Keyloggers are easy to buy and hide on desktop computers but not on laptops. For an example, see KeeLog: KeyGrabber forensic keylogger getting started.
Other hardware alterations are much more complicated and expensive to install. All operating systems, including Tails, depend on firmware to start and run, so no operating system can protect against a firmware attack. In the same way that a car depends on the quality of the road it is driving on, operating systems depend on their firmware.
Keeping your computer in a safe location can protect against some firmware attacks, but some other firmware attacks can be performed remotely. Firmware attacks have been demonstrated, but are complicated and expensive to perform. We don't know of any actual use against Tails users.
Information Security Stack Exchange is a question and answer site for information security professionals. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. In the Tails documentation there is something I find strange. All of which state something similar to the following.
As it is currently impossible to install Tails directly from Linux, this scenario requires creating an intermediary Tails on a second USB stick. This intermediary Tails lacks important security and usability features. The install documentation states the following.
On this intermediary Tails you won't benefit from important features like automatic security upgrades or the possibility to store some of your documents and configuration in an encrypted storage.
They mention that persistent storage is one of the features that is disabled on the first USB. Also, I don't plan on using networking or persistent storage.
The first USB seems to work perfectly for my use case - key generation. It has a terminal and supports mounting other flash drives! This leads me to the following three questions. Online anonymity and censorship circumvention with Tor Tails relies on the Tor anonymity network to protect your privacy online: all software is configured to connect to the Internet through Tor if an application tries to connect to the Internet directly, the connection is automatically blocked for security.
Using Tor you can: be anonymous online by hiding your location connect to services that would be censored otherwise resist attacks that block the usage of Tor using circumvention tools such as bridges What's New: Update Tor Browser to Update Tor to 0. Add a link from the error screen of the Tor Connection assistant to our documentation on troubleshooting connecting to Tor.
Tor Connection Change the custom bridge interface to only allow entering 1 bridge. Increase the timeout to start Tor entirely from seconds to seconds. Allow trying again to connect to Tor from the error screen. Fixed problems Tor Connection Fix connecting to Tor using the default bridges. Software similar to Tails 8.
