About 45 percent of the funds stolen in a third attack targeting Coldcard bitcoin wallets has already been moved, as the attacker continues shifting assets using coinjoin and cross-chain transactions, according to Galaxy Research. It said 97.09 BTC has been moved so far, worth about $7.8 million at the time. Galaxy also identified a new set of 58 addresses that could raise total stolen bitcoin to 1,806 BTC, about $143.9 million at current prices.

A Bitcoin security resource group said it used advanced AI models to inspect about 150 Bitcoin-related repositories and found more than 12 vulnerabilities, which it reported to the respective projects. The group is conducting AI-based security audits across key Bitcoin software, including wallets, cryptographic libraries and infrastructure, as part of building a so-called Bitcoin red team platform. It is also developing an open-source AI platform for Bitcoin software auditing.
