The Bitcoin Entropy Nightmare: ColdCard Vulnerability Analysis Report. Critical Vulnerability in ColdCard Wallets: The $38 Million Crisis.
**🚨 $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.
