“Not your keys, not your coins.”
Unless the keys were predictable. 👀
A Coldcard security incident has reportedly grown into one of the largest hardware-wallet theft investigations on record.
The damage so far:
→ ~2,055 BTC affected
→ ~$130M in estimated losses
→ Vulnerability existed for ~5 years
→ One major wave drained 1,196 addresses in just 41 minutes
And here's the scary part.
The attacker allegedly didn't need physical access to the wallet.
The problem wasn't Bitcoin.
It was randomness.
Some affected devices could reportedly fall back to a weaker pseudo-random process during seed generation, making the possible seed space far easier to attack than intended.
But here's the hidden trap:
Updating the firmware doesn't automatically fix an old seed.
If the secret was generated under vulnerable conditions, patching the device doesn't make that secret random again.
And that's the plot twist.
We often think open-source code means more eyes and better security.
But code being public doesn't guarantee the defenders find the bug before the attackers do.
Square Insight:
Self-custody removes counterparty risk. It doesn't remove software risk.
If a cold wallet can be compromised without physical access, what does “cold storage” actually guarantee?
