Odaily News: According to monitoring by Galaxy's Head of Research, the COLDCARD Wave 3 attacker has moved stolen funds for the first time, exchanging them for ETH via the THORChain cross-chain DEX. This marks the first on-chain transfer of funds from the original hacker address across Waves 1, 2, or 3.
According to monitoring by on-chain analysis firm Galaxy Research (@glxyresearch), the ColdCard wallet hacking incident has developed into a third wave, with an additional 207.73 BTC stolen. Currently, the three waves of attacks have cumulatively stolen 1,367.05 BTC (approximately $88.6 million), involving 4,585 addresses. On-chain data shows that the three waves of attacks exhibit highly similar characteristics: identical fund consolidation topology, identical P2WPKH target addresses, and mixed derivation paths. Each wave occurred approximately 27 hours apart, suggesting they were carried out by the same attacker, but there is currently no direct evidence to confirm this. Currently, all terminal addresses controlled by the hackers hold a total of 1,366.39 BTC (approximately $88.6 million), all of which are in an unspent state on-chain. Galaxy Research noted that the above data is based solely on Bitcoin block data and UTXO set analysis, and has not yet computationally verified whether the victim addresses have vulnerabilities due to low-entropy generation.
