Like I said, yes. AFAIK, Trezor's seed is also BIP39.
Thanks!

It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

Hi everybody!

I recently read that all Trezor models have a hardware vulnerability, which let an attacker extract a seed from a wallet if it's not protected by a long passphrase. It says that the vulnerability cannot be patched by a software update. What is Trezor going to do about it? Are the developers going to fix the hardware for future models or they are going to keep manufacturing the old model with advice to use a long passphrase?

The developers can't fix old models because they would have to change them drastically, including the software. I highly doubt that Trezor is going to release a new model anytime soon (there is still a lot to do for the Trezor T). Also, I don't think that they would suddenly change their security policy. They want to be as much transparent as possible. The attack can't be performed remotely. Passphrases should be used by everyone anyway. Here you can read Trezor's response.

Thanks for the answer.
So, basicaly they admited the proplem but they did not say that they would fix it even in their future devices.

This sentence does not make any sense. Did you mean 'wouldn't fix'? Trezor is not the only device affected by this vulnerability. It looks like that every device with a ST microchip is affected so it's not their fault. Actually, they admitted that they had been aware of it since the beginning. I don't know how many alternatives there are. Ledger uses a different chip which provides 'security through obscurity' that might not appeal to many of the Trezor's customers.

My bad, I fixed the original post.

Too bad, If they knew it, why didn't they choose a different chip?

Did any hard wallet manufacturer offer a reward for revealing hardware vulnerabilities against their devices?
That would be cool Smiley

Has it been hacked as Trezor has?

There might have not been any alternatives. I am not an expert in this field. Ledger HW.1 also had an STM chip in its smartcard.

Yes, both Ledger and Trezor have their responsible disclosures programs. Ledger was supposed not to disclose this vulnerability publicly since it also affects many other devices. No individual has found out about it before them.

Has it been hacked as Trezor has?

There is no comparable hack at the moment for Ledger. Everything has been patched so far.

Since the beginning of October, Trezor beta testers are able to test another beta version of the Trezor Firmware. The latest update added FIDO2 support and an enhancement to Shamir Backup - Super Shamir Backup which allows to divide existing shares into groups. By doing this, one group might need to provide more shares in order to recover the wallet. More information can be found here.

I received an Email from Trezor today, they are having a Holiday sale; buy a Trezor T and get a Trezor one for free, or buy a Trezor T and get a second for half price.  I don't see the promotion on their site, I think it's an email marketing thingy.  If you're not signed up for Trezor promotional emails, they don't send them often, and when they do it's worth getting spammed.  Just sayin'.

If you're interested send me a PM, and I'll send you the links.

It's just not shown on the first page, but if you click the shop button, it will redirect you to all the deals (including the Christmas ones that you're referring to): https://shop.trezor.io/

Trezor has just released a new beta version (2.2.0) of their software for Trezor T. Wipe Code has been added. Once it's entered while the device is locked, it wipes the wallet. In order to set it up, the update has to be installed manually and the code needs to be set up using trezorctl (>=0.11.6).

To set the wipe code use: trezorctl set wipe-code
To remove the wipe code use: trezorctl set wipe-code -r
