According to CoinMeta, a vulnerability in the Coldcard hardware wallet led to the theft of approximately 594 BTC (worth nearly $40 million), which has drawn widespread attention within the Bitcoin community. The founder of Binance, CZ, the CEO of Jan3, Samson Mow, and Strike CEO Jack Mallers have all responded to this incident, reminding users to review the security of their wallets and avoid relying on a single method of protection. CZ pointed out that there may also be issues with hardware wallets, emphasizing that no storage method is perfect. Mow noted that this incident could be more serious than hacker attacks on large exchanges, as it affected users who chose to manage their own security. Mow advised affected users to record all details, including wallet addresses and firmware versions, and to report the case to the police. Mallers also called on users of affected devices to check their wallets as soon as possible to ensure their safety. This incident has sparked broader discussions about wallet security, emphasizing that users should remain vigilant, check their devices, and avoid relying on a single layer of protection.
