[Bitcoin Multi-Signature Hardware Wallet Frostsnap Fixes Two Security Issues, Team Urges Users to Update Promptly] BlockBeats News, August 27: Bitcoin multi-signature hardware wallet Frostsnap has released version v0.4.0, addressing two security issues and stating that no user funds have been reported lost. The two issues include: 1. (FSA-2026-001): A malicious signature request could mark a specific output as 'belonging to the user's wallet.' The device did not verify this claim, nor was it displayed on the confirmation screen, potentially leading to funds being transferred to an address unfamiliar to the user. 2. (FSA-2026-002): The change address could fall outside the wallet's recovery scan range, causing funds to appear missing after a backup recovery, even though they remain in the wallet. After the update, the application will prompt users to upgrade the device firmware and introduce firmware downgrade protection. The team recommends updating the application and firmware as soon as possible. [Original Link]
