Coldcard 2021 Firmware Vulnerability Led to Over $100 Million in Bitcoin Theft

Odaily News: A 2021 firmware vulnerability in the hardware wallet Coldcard resulted in insufficient randomness in some recovered seeds. Since July 30, attackers have transferred approximately 1,600 to 1,800 BTC from affected wallets, involving thousands of addresses, with an estimated value exceeding $100 million.

Coldcard manufacturer Coinkite stated that it must be assumed that someone used AI to review its public firmware. The vulnerability has existed for about five years, and whether AI was involved in the related attacks has not yet been confirmed.

Shielded Labs researcher Taylor Hornby used a Claude Opus 4.8 audit agent and discovered a vulnerability in the Zcash Orchard shielded pool circuit dating back to 2022, which in testing could generate unlimited counterfeit ZEC without a trace. Developers completed the fix within days, and no theft of coins has been confirmed.

Statistics from blockchain analytics firm Chainalysis show that on-chain writes carrying malware instructions and command-and-control information rose from about 2.06 per day to 11.1 per day, an increase of 440%. (Bitcoin.com News)

"This is going to the Supreme Court, and I think the states and the tribes will prevail," he said. (The Block)
Trader Killa: Bitcoin's Short-Term Choppy Action May Be a "Liquidation Game," Next Key Level to Watch Is $75,500
Odaily reports: Trader Killa says that for Bitcoin (BTC) to replicate its 2023 price action, it needs to form a higher low (HL) above $75,500 and ideally hold the low near $80,000.After Bitcoin recently reclaimed its short-term structure around the $82,000 zone, it pulled back to test and broke through again, with short-term price action showing strong characteristics of "bull traps and bear traps." When BTC previously fell from $84,100 to $81,000, the structure appeared weak, but a large number of shorts entering at the lows fueled the subsequent rebound.Killa noted that during the drop from $84,100 to $81,000, long liquidations totaled approximately $300 million, while during the earlier decline from $86,800 to $80,600, long liquidations exceeded $2 billion, indicating that the market's leverage structure is improving and the proportion of longs has declined compared to before. The market now needs to form a higher low and initiate the next leg up; otherwise, this correction could break below $80,000.
