Keystone, a maker of air-gapped cryptocurrency hardware wallets (formerly known as Cobo Vault), disclosed in late October 2026 that an attacker breached its Shopify-backed website, stealing customer order data and, in a more serious escalation, a cryptographic key the company uses to verify that its devices are genuine. Keystone said no seed phrases, private keys, or payment details were taken, but it could not rule out counterfeit devices among units shipped after the breach and announced it would destroy over 18,000 affected units in its own inventory. The incident also revealed that Keystone's automated data-deletion tool had failed silently for an extended period, undermining its public '180-day data deletion' promise.
