116 Million Dollars Drained

116 Million Dollars Drained. No Phishing. No Physical Access. 🔓💻 How did some of the world's most secure cold wallets get emptied in minutes? It was not a flaw in Bitcoin itself. It was a four line coding error that sat hidden for five years. The Hack Breakdown: ⛓️ The Silent Flaw: Back in 2021, a firmware update accidentally disabled the device hardware random number generator. Instead of using true randomness, it used a predictable software formula based on basic info like the device clock. 🧮 The Arithmetic Attack: Because the random seeds were no longer random, hackers did not need your device or your PIN. They simply did the math offline to guess the keys and checked them against the blockchain. ⚡ The 41 Minute Sweep: In the first major wave on July 30, 2026, attackers drained over 1,000 BTC from 1,196 addresses in just 41 minutes. Total Damage so far: 💰 Over 116,000,000 dollars stolen 👛 5,200 plus addresses affected 📉 Bitcoin social sentiment hit record lows as safe storage was put to the test. Are you at risk? 🛡️ If you generated a Coldcard seed between March 2021 and July 2026, your funds may be vulnerable. ⚠️ Crucial: Updating your firmware alone does not fix an old seed. You must generate a brand new seed on the patched firmware and migrate your funds immediately. Knowledge is your best defense. Stay safe out there, stack sats carefully, and double check your entropy! 🛡️₿ #Bitcoin #Coldcard #CryptoSecurity
