Coldcard isolation bypass

Responsible disclosure of a Coldcard vulnerability that allows an attacker to spend your bitcoins when you think you are signing a testnet transaction.

Security

How nearly all personal hardware wallet multisig setups are insecure

If you use hardware wallets in a Bitcoin multisig setup, using a single computer to handle them, you are likely to be exposed to remote theft or ransom attacks.
