Block hardware lead Clay Garrett shares initial findings on a separately reported Bitkey vulnerability disclosed by 1440000bytes, stating it requires exceptional circumstances during inheritance setup, yields insufficient key material even if exploited, and that a mobile-app patch ships same day. Recorded because Block is a primary party in the COLDCARD incident record and this statement shows its concurrent security posture; the Bitkey issue itself is distinct from the COLDCARD RNG flaw.
