Coldcard Hacker Converts Stolen Bitcoin to ETH Using THORChain

WHY IT MATTERS

A hardware wallet is a physical device used to store cryptocurrency offline, which is generally considered one of the safest ways to hold crypto. Think of it like a secure USB drive for your digital money. When a hacker manages to steal from one, it is notable because these devices are specifically designed to prevent that. In this case, the hacker then used a decentralized protocol called THORChain to swap the stolen Bitcoin for a different cryptocurrency, Ether. THORChain works like a currency exchange that has no central operator — no one can block a transaction or freeze an account. While this permissionless design is a core feature of decentralized finance, it also means bad actors can use it to move stolen funds across different blockchains, making the money harder to trace. This story illustrates the ongoing challenge of balancing open, censorship-resistant financial tools with the need to prevent criminal misuse.
