IF YOU OWN A COLDCARD, STOP READING SOCIAL MEDIA AND READ THIS. YOUR FUNDS MAY BE AT RISK RIGHT NOW.
🚨 CRITICAL: A SECURITY BUG HAS BEEN FOUND IN EVERY COLDCARD EVER MADE
Every single Coldcard device — MK3, MK4, MK5 and Q — has a critical security bug. This is not a rumor. This is not FUD. This is a security advisory that Bull Bitcoin just sent to ALL of its clients.
If you have a Coldcard and did NOT use a passphrase, you are at IMMEDIATE risk.
The Bug That Breaks “Not Your Keys, Not Your Coins”
Weak entropy during seed generation means an attacker can recompute your private keys from the pattern — with no access to your device. They never touch your hardware. They never see your PIN. They just do the math.
And if you think “but I have a passphrase,” think again. The risk just depends on how long and complex your passphrase is. If you’re not sure it’s secure, assume it’s not.
⚠️ DO NOT ASK AN AI TO VALIDATE YOUR PASSPHRASE
Bull Bitcoin said it directly: “Never ever let an AI generate or validate your passphrase.”
AI will tell you what you want to hear. The math won’t.
Who Is Safe?
Only if you set up your Coldcard with the dice roll option and rolled ~100 times. If you didn’t roll the dice, or you’re not sure, or you don’t remember — assume you’re affected.
What To Do RIGHT NOW
Option 1: Move your funds NOW (recommended)
Download the Bull Bitcoin mobile wallet, write down your seed words, and send all your funds there immediately. Your funds stop being at risk the moment they leave the Coldcard.

Option 2: Fix your Coldcard with a new dice-rolled seed
Update firmware → Advanced/Tools → Temporary seed → Generate Words → 24 Dice Roll → roll 100 times → write down seed → add a STRONG passphrase → test recovery → then move funds.
Both options work. But Option 1 is faster and removes the risk instantly.
The Punchline
You bought the “most secure hardware wallet on the market” and it turned out to have a bug in the ONE thing that matters: randomness.
The self-custody narrative took a massive hit today. The lawsuits are coming. The thefts will continue.

Act now, but do not rush. A panicked migration can lead to a loss. If you’re anxious, work with a professional.
