Just learned that a hardware wallet manufacturer discovered >4 vulnerabilities on other wallets over time

The hardware manufacturer is Bitbox, and all were responsibly disclosed:

• Remote multisig theft attack (Coldcard, 2020/11)
• Ransom attack on passphrase handling (Trezor/Keepkey, 2020/08)
• Bitcoin mainnet/testnet cross-account signing (Coldcard, 2020/08)
• Malicious Change in Mixed Transactions (Trezor, 2020/03)

There may be more of them that I haven't found.

This is extremely impressive from them.

Additionally, they were the first to make their hardware wallet (the Bitbox02) resistant against a very advanced attack: the nonce-covert channel attack. AFAIK this attack has never taken place yet, and the only hardware wallets resistant to it are the Bitbox02 and the 3 Blockstream Jades.

Disclaimer: I do not work for Bitbox, but have been a fan of them for a while and think they're underrated. I'm also fan of Blockstream and their Jade wallets.
