ChainCatcher report, according to Decrypt, the privacy-focused Bitcoin wallet Sparrow Wallet has released version 2.5.4. Developer Craig Raw stated that this update was driven by AI-assisted code review, with most fixes originating from this review. The review was prompted by the此前 Coldcard seed generation code vulnerability incident and the release of unrestricted Chinese AI models, which have significantly enhanced the ability to search for vulnerabilities in large codebases. Key updates include: validating the legitimacy of transactions returned by Electrum servers, strengthening security requirements for BitBox02 hardware wallets (firmware version 9.4.0 or higher required), fixing local DNS leaks, and hiding sensitive credentials in debug logs. Raw noted that no signs of exploitation have been found and user funds are not at risk, but still recommends all users update as soon as possible.
