It’s misleading to claim the device can be hacked in 15 minutes. Executing this attack requires significant preparation and expertise as well as specialized equipment, and assumes physical possession of the device.

Regardless, KeepKey owners can help prevent the attack by enabling the BIP39 passphrase on the device. Enabling this passphrase has always been the best practice for maximum security with KeepKey and similar hardware wallets.

Crypto users must be focused on security at all times, which includes awareness about protecting their physical devices. The only way to protect data on any device is to encrypt that data first. This means that no hardware wallet on the market today can keep keys safe from physical attacks unless strong encryption is used.
