Keystone Cannot Guarantee Authenticity of Wallets Delivered After Oct. 20

Keystone said it cannot guarantee the authenticity of hardware wallets delivered after Oct. 20, after an attacker accessed its website and took a key used to check whether its devices are genuine. The company said the key could allow counterfeit wallets to pass its authenticity check and reach customers as genuine products, putting buyers’ assets at risk. Customers with devices delivered after Oct. 20 should contact Keystone support for additional verification. Keystone considers wallets that were both manufactured and delivered before the incident safe and says their authenticity checks remain reliable.
