A recent spate of hacks has targeted Bitcoin owners using Coldcard offline hardware wallets, with hackers exploiting a bug to steal over $130 million. At least a dozen different hackers are involved, according to blockchain security firms monitoring the heists.

The thefts have significant implications for the cryptocurrency industry, which has seen over 200 hacks reported this year, totaling over $950 million in losses. Regulators and industry experts are calling for improved security measures to prevent such incidents in the future.

The Coldcard wallet is designed to be secure and offline, allowing users to store their secret key or seed phrase, essentially a password, in a device not connected to the internet.
