What Keystone Is Doing About It

The company will destroy 18,835 units in stock and halt production shipments until a new key is in place. Devices delivered before October 20 remain trusted. Anyone who received a wallet after that date should contact support for verification.

Buyer Data Left Exposed

A faulty cleanup tool kept 25,964 Shopify buyer records from 2024 to 2026 that should have been erased. Another 12,873 unfinished checkouts were also reachable.

Ledger, Coinkite, Trezor, SafePal and BitBox have all faced supply chain, bug or data incidents in 2026.
