[Approximately 594 BTC Consolidated from 500 Single-Signature Addresses to a Wallet, Cause Undetermined] According to Bitcoin News, on Thursday, approximately 594 BTC (valued at around $38 million) were transferred out of 500 addresses within 25 minutes, and the funds were subsequently consolidated into another wallet. All affected addresses used single-signature addresses, with balances ranging from approximately 0.15 to 0.26 BTC, and many UTXOs had been dormant for years. Early speculation pointed to Coldcard, as at least one victim was using this device. Coldcard CEO NVK denied claims of device-level vulnerabilities, stating that the user may have imported previously leaked or weak mnemonic phrases and noted that the incident involved private keys from different wallets.
