Keystone Breach Widens as Attacker Grabs Its Device Authentication Key

The hardware wallet maker will destroy 18,835 old devices and says it can't fully rule out fakes among units received after Oct. 20th. Keystone’s store breach just got a lot more serious. In a fresh update on Monday (Oct. 26th), the hardware wallet maker said the attacker behind the breach it detected on Oct. 20th also took the key it uses to confirm devices are genuine. As a result, Keystone is scrapping the 18,835 wallets in its inventory that carry that key.
