A hacker who exploited Coldcard has transferred approximately 10% of the stolen Bitcoin through the cross-chain platform THORChain, moving the assets to a new Ethereum address. This movement was tracked by researchers following the flow of the stolen funds.
According to CoinTelegraph, this marks the third wave of exploitation involving Coldcard, highlighting ongoing security challenges within hardware wallet ecosystems. The use of THORChain suggests an attempt to obscure the trail by converting Bitcoin into Ethereum-based assets.
For Japanese investors, this incident underscores the importance of robust security measures in crypto holdings, especially as cross-chain protocols become more commonly used in laundering stolen assets or moving funds across different blockchain networks.
