Hackers discovered a vulnerability in a Bitcoin “cold wallet” software. This type of wallet has always been considered one of the safest ways to store cryptocurrencies, yet attackers are using this vulnerability to continue stealing tens of millions of dollars worth of cryptocurrencies. The Canadian company Coinkite Inc. informed Coldcard hardware wallet users last weekend that there was a security flaw in the key generation mechanism that protects their Bitcoin, and that some wallets have been affected. According to Galaxy Research data, as of Monday, the attackers had transferred more than 1,755 bitcoins from about 5,000 wallets, which was about 110 million US dollars based on the market capitalization at the time. Coldcard is a hardware wallet, and users can use this device to store bitcoins in so-called “cold wallets.” Cold wallets have long been considered the safest way to store cryptocurrencies due to their isolation from the internet.
