This is worse than any previous Bitcoin exchange hack. It is arguably one of the worst things that could happen.

The popular hardware wallet COLDCARD has a faulty random number generator (RNG). Funds are being drained from ordinary users’ hardware wallets as you read this.

Users first reported to Block less than 24 hours ago that funds were moving out of their wallets. The exploit was most likely discovered with the help of AI. Block has confirmed that the RNG is broken. You know what that means.

There are likely already multiple attackers competing for the affected BTC. Many more will join very soon.

Nobody knows how much BTC is affected.

Nobody knows how many users are affected.

This attack has only just begun, and it will continue until all affected BTC has been drained unless users secure their funds first. Inevitably, many Bitcoiners will not hear about the incident early enough to respond in time.

I am truly saddened for everyone affected, especially those who may have just lost their life savings.

The worst part is that they did everything right.
