    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 minute

    1/2. Congrats for contributing to secure the ecosystem! Your attack is very close to the one we implemented a year ago As the attack is not fixable, we preferred not sharing the details to avoid exploitation on the field.

    hat gerade einen kritischen Sicherheitsmangel in den Wallets von aufgedeckt. Es ist wichtig, dass das Wallet nicht in die falschen Hände gerät. Wie das auch schon aufgezeigt hat.

    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]
