A global cybersecurity crisis escalated after a firmware exploit targeting Coldcard Bitcoin cold storage wallets and connected BTCPay Server infrastructure drained over 100 million dollars from thousands of user addresses. The breach originating from an entropy vulnerability in legacy firmware compromised self custody wallets previously considered offline and secure. In response Bull Bitcoin Chief Executive Officer Francis Pouliot urged operators to deactivate BTCPay server infrastructure immediately to prevent further digital asset exfiltration. Meanwhile an emergency security red team organized by AnchorWatch Chief Executive Officer Rob Hamilton deployed open weight artificial intelligence tools including Moonshot Kimi K3 spending ten thousand dollars daily to audit core cryptocurrency code repositories and identify newly exposed vulnerabilities. Wallet manufacturer Coinkite issued mandatory firmware update instructions and advised customers to migrate capital to fresh cryptographic seed phrases. Federal authorities and blockchain analytics firms are currently monitoring on chain movements as hackers attempt to launder stolen assets.
