Galaxy Research: Coldcard attackers continue to transfer funds, approximately 45% of the stolen assets have entered mixing or cross-chain pathways

Galaxy Research published that the attackers in the Coldcard "Wave 3" attack are still continuously transferring the stolen funds. During this phase, the attackers created 293 2-of-2 multi-signature wallets for each victim's assets. The first batch of funds was transferred across chains to Ethereum via THORChain; the latest round of transfers has begun entering the CoinJoin mixing process.Currently, the Wave 3 attackers are processing the largest amounts of stolen funds in order of the stolen amount, having sequentially transferred the funds from wallets ranked 1 to 11. The next 10 wallets that have not yet been transferred hold a total of 30.81 BTC, while wallets ranked 61 to 293 hold a total of 33.77 BTC. So far, the attackers have transferred about 45% of the stolen assets from this exploit, with funds flowing to Ethereum (via THORChain) or entering CoinJoin mixing transactions. Additionally, this fund transfer has revealed a previously unknown wallet: 58 addresses jointly spent in a 2-of-2 multi-signature format identical to that of Wave 3, and these were further transferred by the Wave 3 attackers to a jump address that funds CoinJoin.The on-chain analysis team currently marks this wallet as "cause = open," but believes it likely also belongs to Coldcard victims, which means the number of wallets involved in Wave 3 may increase to 294, raising the previously reported total amount stolen from the Coldcard vulnerability to approximately 1806 BTC. Currently, about 82% of the stolen BTC remains in addresses initially controlled by the attackers, while about 18% has been transferred, with the flow of funds indicating that it may be undergoing laundering processes.

first_img Analysis: Japan's government bond yields hit a 30-year high, while Bitcoin is trading sideways at $78,000

According to Cointelegraph, the global bond bear market continues to ferment, with Japan's 10-year government bond yield rising to 3% on Tuesday, the first time since 1996; the 30-year government bond yield also broke through the historical high of 4.18%. The U.S. 10-year government bond yield simultaneously rose to a multi-year high of 4.78%, and global long-term sovereign bond yields are at their highest level since the 2008 financial crisis.In this context, Bitcoin remains in a sideways consolidation, maintaining around $78,000, slightly retreating from an earlier high of nearly $79,000. There is a dense resistance area between the current spot price and $86,000, which limits Bitcoin's upward momentum. Market sentiment remains cautiously optimistic in the short term, with the $76,000 to $82,000 range seen as a key battleground in the coming weeks.This round of selling occurred after U.S. Treasury Secretary Yellen announced an increase in the upper limit of government bond repurchase transactions to $4 billion starting in September, with some commentators likening it to a form of yield curve control. Arthur Hayes has long argued that the Federal Reserve will eventually activate the FIMA repo facility, a mechanism that will create new dollar liquidity, which is also why he recommends allocating Bitcoin, gold, and cryptocurrencies; Yellen hinted at the future use of this tool as early as August.
