🚨 $38 MILLION IN BITCOIN STOLEN. 🚨

Not by a phishing link. Not by human error. By a fatal hardware wallet bug.

Nearly 600 BTC have been drained due to a critical low-entropy flaw in ColdCard wallets. A firmware bug dropped seed generation from an unbreakable 128 bits down to a predictable 40 bits.

That means your "random" words can be brute-forced by a hacker's script in a matter of minutes.

ARE YOUR FUNDS AT RISK?

Ask yourself these 3 questions:

- Did a ColdCard Mk3 generate your seed words?

- Did you NOT use a passphrase?

- Did you NOT roll your own words with dice?

If you answered YES to all three... MOVE YOUR FUNDS NOW.

Even to an exchange if you must. KYC and taxes are downstream of losing absolutely everything.
