2/2. The attack is indeed feasible with a low-cost hardware. We built our own card to ensure this. With a few additional efforts you might be able to dump the WHOLE chip in less than 1 minutepic.twitter.com/YuUvvcPpOy

1/2. Congrats
@kraken for contributing to secure the ecosystem! Your attack is very close to the one we implemented a year ago https://donjon.ledger.com/Unfixable-Key-Extraction-Attack-on-Trezor/ … As the attack is not fixable, we preferred not sharing the details to avoid exploitation on the field.https://twitter.com/krakenfx/status/1223253508956266496 …Prikaži ovu nitHvala.

@krakenfx hat gerade einen kritischen Sicherheitsmangel in den Wallets von@Trezor aufgedeckt. Es ist wichtig, dass das Wallet nicht in die falschen Hände gerät.

1/ My take on Shamir Secret Sharing SSS is an elegant method to split a secret into n shares such that: - Any quorum of k (<= n) shares are enough to reconstruct the secret - Any quorum of m (< k) shares gives NO information on the secret [ex of quorums k=2, n=3 or k=3,n=5]pic.twitter.com/f8CZLhynFu
