Model One users will benefit from the path isolation check fix noted below; this update is highly encouraged if you use your Model One for altcoins, but not urgent if you are only transacting Bitcoin. Auto Lock. Auto lock functionality has been added to the Trezor Model T.
This feature adds another layer of protection whenever your Trezor is left connected for long periods. Previously only available on the Trezor Model One, it makes your device lock itself after a certain time limit. The default lock time setting of ten minutes will be applied when you update your firmware.
You can unlock it by touching the screen and entering your PIN when prompted. Feedback from our users has shown that many of you tend to have your devices connected for long periods, which could leave you exposed to someone using your device while you are not present.
You can follow this guide to trezorctl to configure auto lock. The auto lock feature can be thought of as a soft lockdown; when auto lock triggers, your device is locked but stays connected to and recognized by the computer. You can still access your Trezor Wallet but can not use it, in contrast to the default state of your Trezor upon plugging it in, where no connection takes place until it is unlocked.
Missing path isolation check. We have amended our Trezor One code to include a missing path isolation check, which is already in place for the Trezor Model T. Without this check, an attacker could trick the user into signing a Bitcoin transaction while thinking they are signing a testnet or altcoin transaction.
Other Changes. Some of the more notable changes include:. Trezor Model T. Trezor Model One.

Details of firmware updates for Trezor One (version 1.9.0) and Trezor Model T (version 2.3.0)
The security issue was brought to our attention by an individual researcher, via our Responsible Disclosure. They described the issue and proposed a fix to the problem as well. Together with them and Jochen Hoenicke, we developed and tested a firmware update, which we are rolling out now. It is important to note that this is not a remote execution attack. To exploit this issue, an attacker would need physical access to a disassembled TREZOR device with uncovered electronics.
It is impossible to do this without destroying the plastic case. If your device does not leave your presence, your coins are safe.
Moreover, if you have a passphrase enabled and actively use it, your coins are safe. We are not releasing a detailed description of the issue today to give enough time for users to update and for other hardware wallets based on TREZOR to distribute an update.
We will publish a detailed report in the coming days. Currently, this update will be marked as optional. In order to exploit this issue, an attacker would have to break into the device, destroying the case in the process. They would also need to flash the device with a specially-crafted firmware.
If your device is intact, your seed is safe, and you should update your firmware to 1. With firmware 1. If you use a passphrase, even if the attacker broke into your TREZOR and extracted your seed, your coins would still be safe. Most likely, yes. If the Wallet tells you your firmware is outdated, please do update your device. We have reached out to other producers of hardware wallets and informed them about the issue.
We will release a detailed technical report on this issue in the coming days. Thank you for understanding. Sign in. SatoshiLabs Follow. Changelog Firmware 1. Bitcoin Trezor Firmware Updates.

Apart from various functional improvements and minor fixes, these updates address and fix three notable vulnerabilities found in recent months. If you want to learn about the in-depth technical details of these security updates, check out the separate Dev Corner article here. Patching security issues is always a challenging but positive experience, and we truly appreciate the knowledge brought to this conversation by everyone who worked with us.
We worked with some of the best-known experts in the field of embedded hardware security demonstrating Trezor is an essential part of both the open source hardware and Bitcoin communities, and we aim to remain the innovation leaders in these two areas. Communication with all involved parties was very professional and focused on a common goal: improving the overall security of the solutions we provide to our users.
These changes also opened new doors for further improvements. Exploiting either of these vulnerabilities requires physical access to the device.
An attacker also needs a specialized hardware connected to Trezor device to perform the attack. Those who use passphrases to protect their wallets are unaffected unless they disclosed their passphrase to the perpetrator. At the time of writing this article, there is no evidence that any of these vulnerabilities have ever been exploited outside of the lab to extract any data. As always, we strongly recommend keeping all Trezor devices updated with the latest firmware to maintain the maximum level of security.
Is my Trezor safe? The previously described vulnerabilities can only be exploited after gaining physical access to your device and taking it apart. Both attacks are fairly sophisticated, requiring substantial know-how and experience. Some of the crucial information needed to exploit these vulnerabilities has never been published. Is Trezor Model T affected? There is no evidence that the Trezor Model T could have been directly affected by these vulnerabilities.
Nonetheless, our developers made the appropriate updates to the Trezor T code to mitigate any possible future risks, even hypothetical ones. How can I update my Trezor? You will find the step-by-step instructions in our User manual. Before you start, make sure to have your recovery seed ready at hand. Please note that if your Trezor One device is currently running firmware version 1. Please make sure you have the correct recovery seed with you, as you will need to recover your Trezor device from seed backup.

It offers unmatched security for cryptocurrencies, password management, and serves as the second factor in Two-Factor Authentication. These features combine with an interface that is easy to use whether you are a security expert or a brand new user. Trezor Model T is the next-generation hardware wallet, designed with the benefits of the original Trezor in mind, combined with a modern and intuitive interface for improved user experience and security.
It features a touchscreen, faster processor, and advanced coin support, as well as all the features of the Trezor One. Sign in. Firmware updates for Trezor One firmware 1. SatoshiLabs Follow.In computing, firmware is a computer program that provides the low-level control for the device's specific hardware.
Since Trezor is a simple device, its firmware acts as a complete operating system. Trezor firmware is a key component of the device security and is also responsible for all of its basic and advanced features. To enable future enhancements and security updates, the firmware of the device can be updated when a new version is published using Trezor Wallet or other compatible interfaces with managing capabilities.
To prevent malicious updates, only firmware properly signed by SatoshiLabs can be installed without additional user confirmation. See the firmware changelog for the latest firmware. Actions: Updating the Trezor device firmwareWipe device.
Jump to: navigationsearch. Important All Trezor devices come without firmware installed to ensure that the latest firmware is installed when the device is delivered. Important For security reasons, an unsuccessful firmware update or a successful one using unofficial firmware will wipe the device from any private information including your recovery seed.
TREZOR Firmware Security Update — 1.5.2
Namespaces Page Talk. Views Read View source History. Personal tools Log in.This Wednesday we are releasing the firmware update 1. This post describes the new features and security fixes brought by these updates. Passphrase is an important part of the whole Trezor ecosystem. In these firmware updates we have overhauled the design and made many internal improvements and two major user-facing changes. First, on both of our device models, we are introducing passphrase caching.
Up until now, if you used multiple passphrases, you had to enter the passphrase again every time you switched to a different passphrase-protected wallet. Depending on the usage, Trezor is now capable of caching up to 10 passphrases at the same time.
This does not concern the Wallet at the moment because it requires Trezor to be reconnected to change the passphrase.
However this is ready for the next generation of our wallet, which is coming soon. Stay tuned! Second, on Trezor Model T, the decision whether the passphrase will be entered on the device is prompted directly in the Wallet see picture below. On the other hand, if you like to be asked for the passphrase on the device every time, you can use trezorctl set passphrase enabled --force-on-device to enforce that. If the wipe code is ever entered into any PIN entry dialog, then all private data will be immediately erased from your Trezor and the device will be reset to factory defaults.
You can write the wipe code somewhere near your Trezor as a decoy PIN, so that if someone tries to unlock the device without your consent, they will cause it to wipe itself. To enable this feature you will need trezorctl version 0. The command to set or change the wipe code is: trezorctl set wipe-code. Note that when changing the wipe code you first need to enter your PIN. Trezor never asks for the old wipe code, so if you accidentally enter it, the device will get wiped!
To disable the wipe code feature use: trezorctl set wipe-code -r. While showing a multisig address on the Trezor device, a user can also show individual XPUBs which are involved and confirm that the address is correct.How to Update Trezor Firmware 1.6.2
This feature serves as additional protection against physical attacks on the Trezor Model T. When it is enabled, a randomly generated secret is stored on the microSD card that you can insert into your Trezor Model T. During every PIN checking and unlocking operation this secret is combined with the entered PIN value to decrypt data stored on the device. Simply put, the device gets bound to the SD card and cannot be unlocked without it until you intentionally disable the feature or factory-reset your Trezor.
Thus if you are concerned about physical attacks, you can remove the SD card whenever the device is not in use and keep the two in separate locations.
One without the other is worthless to an attacker, because the SD card secret is an entirely random value which carries no information about your seed or passphrase.
If the card is not properly formatted, then Trezor will offer to erase and format the card for you. There are three commands related to SD protect:.
Firmware updates for Trezor One (firmware 1.8.0) and Trezor Model T (firmware 2.1.0)
The refresh command replaces the current SD card secret with a new one. This is useful if you inserted the SD card into a malware-infected computer and are worried that the secret stored on the card may have been compromised.
This round of updates also brings five fixes to security vulnerabilities. Four of them were reported by a long-time contributor to Trezor: Saleem Rashid, while the last one was reported by Sebastian Kung. Thank you! This vulnerability was present only on the Trezor Model T.
How was the vulnerability fixed? Trezor now strictly validates all transaction outputs before signing. We also make sure an output is only marked as a change-output if the script type matches the correct subset. In order to be able to sign large transactions with many inputs or outputs, we came up with a technique called streamed signing. This process has two main phases.The purpose of this guide is to help the user to update the Trezor device firmware.
