Summary
- An attacker exploited a flaw in how some Coldcard hardware wallets generated keys to steal roughly 594 bitcoin, worth about $38 million, from around 500 single-signature wallets in under 30 minutes.
- The vulnerability, introduced in Coldcard firmware 4.0.0 in March 2021, caused devices to skip their hardware randomness generator and fall back to predictable software-based key generation seeded by nonsecret chip data.
- Coinkite has warned users who created seeds on Mk3 devices running firmware 4.0.1 or later, while stressing that Mk4, Q and Mk5 appear unaffected so far, and the theft has had little visible impact on bitcoin’s market price.
A Major Flaw in Bitcoin Wallets Exposes Users to Significant Losses

Exposure depends on the firmware the device was running at the moment the wallet was first created, not on when the hardware was bought.
A wallet’s seed, the secret phrase controlling the funds, is meant to be drawn at random from a pool so vast that guessing is hopeless.
