Observe your traffic. Pretend to be the destination server, a technique known as machine-in-the-middle attack MitM. That is why you should pay even more attention to the security warnings in Tor Browser. If you get such a warning, use the New Identity feature of Tor Browser to change exit node. 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.

Deprecation of the Tails Verification extension This new verification procedure is: Simpler and faster for first-time users Compatible with more web browsers, for example, Edge and Safari As secure as the Tails Verification extension From the logs on our website, it seems like only a minority of downloads are currently being verified.

Without advanced knowledge of OpenPGP, verifying with OpenPGP provides the same level of security as the JavaScript verification on the download page, while being much more complicated and error-prone. Providing basic and never exhaustive instructions has proven to be very time consuming to our help desk and technical writers. See Allow verifying any current Tails image: downloaded over BitTorrent, copied from a friend, downloaded from one of our mirrors. This threat is taken care of by the internals of the browser and the proper coding of the JavaScript.

Since the JavaScript verification is targeted at new users, a MitM or exploit on our website could defeat any verification technique by providing simplified instructions or by faking the verification. To prevent this kind of attack we should instead:. Such an attacker could do attack [C] as well but in such a way that could be much harder to detect for example by serving malicious content only to some users.
