Keystone hack let attackers steal wallet authenticity verification key

Keystone has escalated its disclosure of a security breach, revealing that hackers stole a key used to verify wallet authenticity, not just customer information. The stolen key could let counterfeit hardware wallets pass authenticity checks, undermining trust in the device supply chain. Traders holding assets on Keystone devices should verify their hardware and consider moving funds, as compromised verification weakens confidence in self-custody hardware.
