🚨 Over 1,000 $BTC (~$80M) drained from cold wallets in 25 minutes.
And the attacker didn't touch a single physical device or hack the blockchain. 😐
How it happened:
🔸 A 2021 firmware bug disabled the hardware RNG on Coldcard.
🔸 Seed phrases were generated using weak, predictable code instead of true randomness.
🔸 The hacker derived the keys offline and set automated sweeps once wallets were funded. 🔻
⚠️ CRITICAL WARNING:
If your seed phrase was generated on affected firmware, updating the device WILL NOT protect you. Your keys are already exposed.
You must generate a brand-new seed phrase on safe firmware and move your funds immediately.
Does true 100% self-custody security exist, or are software flaws always going to be the weakest link? 🤔
