Theft of 1,367 Bitcoin from Coldcard wallets due to firmware vulnerability 🚨
Theft of 1,367 Bitcoin from Coldcard wallets due to firmware vulnerability 🚨
Background
* Announcement by Galaxy Research regarding the theft of 1,367 Bitcoin worth approximately $89 million from 4,585 different addresses
* Main source of the attack: Presence of a software bug in Coldcard firmware that caused the generation of predictable private keys
* Occurrence of this major theft during three separate waves of attacks
Focus
⚠️ Structural vulnerability in the way private keys are generated has challenged the security of hardware wallets
🌐 Change in hackers' tactics in the third wave and transferring assets to separate addresses with more complex structures to disrupt tracking
📉 Based on the "USD Sent per Transaction Over Time" chart, the average dollar value transferred per transaction has decreased over time and the chart has trended toward zero
Consequences
🛑 The decrease in the value of stolen Bitcoin in each new transaction indicates that most vulnerable wallets were drained in the initial waves
⚠️ Necessity of immediate firmware updates for hardware wallets and transferring assets to new, secure keys
Conclusion
🎯 Despite this vulnerability, the decreasing slope of the value of hacked transactions shows that the initial crisis is subsiding, but it is a serious warning to review key generation algorithms 📊
