According to a post by Galaxy Research, as of now, approximately 1719 BTC have been confirmed stolen in the Coldcard hardware wallet vulnerability attack, valued at around 111 million USD. Several other transactions are still under verification, and the total loss is expected to exceed 130 million USD. If the unverified portion is ultimately confirmed, the scale of theft could reach over 2300 BTC. In addition, collaborating researchers have received reports from more than 250 victims. Based on the loss situation from the first three waves, most victims are ordinary Bitcoin holders rather than whales.Galaxy Research stated that it is currently tracking over 25 independent attack patterns, including the previous first to third waves, indicating that multiple different threat actors are actively exploiting the vulnerability. All addresses corresponding to the stolen coins were created after the affected firmware was released on March 17, 2021. There is currently no evidence that the vulnerability affects other signing devices or wallets outside of the Coldcard Mk3, Mk4, Mk5, and Q series firmware released after that date.

Bitcoin News posted on the X platform that BTCPay Server stated a serious vulnerability is being actively exploited, which may lead to financial loss. Users should immediately update to BTCPay Server v2.4.2; users who cannot update immediately should shut down their BTCPay Server until the update can be installed to prevent unauthorized access.

The State Taxation Administration of China responded to the recent discussions on taxing insurance income in Hong Kong, stating that Chinese tax residents are required to fulfill their tax obligations on global income according to the law, and that overseas insurance income also falls within the scope of taxable income. This is not a new policy and is not specifically aimed at the Hong Kong insurance market. The tax authority indicated that residents must declare and pay taxes on overseas insurance income and other investment income in accordance with the law, and the relevant rules treat overseas income from different countries and regions equally.Yesterday, Caixin reported that with the normalization of CRS information exchange, Chinese tax authorities can now fully obtain data on dividends and cash value from overseas insurance policies, gradually filling the gaps in tax administration. Currently, the taxation of insurance income from overseas sources has been initiated.

Ethereum co-founder Vitalik Buterin stated that Signal recently announced it is exploring allowing users to register accounts without a phone number. He welcomed this move, believing it helps reduce reliance on the highly oligopolistic system of phone numbers, lowers the identity security risks associated with SIM card swaps, and makes it more difficult for governments to pressure Signal to ban users based on nationality.Vitalik also pointed out that while this initiative is better for privacy protection than the current situation, it only achieves "confidentiality" and does not reach true anonymity, as metadata such as message sending time, frequency, and recipients could still be used for identity correlation. He believes that with the development of artificial intelligence technology, long-lasting anonymous accounts are becoming outdated, and the only defensible form of privacy is "message-by-message uncorrelatable," meaning that no one other than the sender and receiver knows the identities of the communicating parties. This direction is currently being explored and advanced by new communication tools and mixing network projects such as Session and SimpleX. Additionally, protection against spam and denial-of-service attacks will become the next key issues to address.

In July, the United States unexpectedly lost 23,000 jobs, far below the expected increase of 80,000. The increase in June was also revised down to only 20,000. Despite the weak job market, the unemployment rate unexpectedly fell from 4.2% to 4.1%. "Fed mouthpiece" Nick Timiraos commented that in July, the U.S. unemployment rate dropped to 4.09% because both the number of job seekers and the number counted as unemployed decreased; this data brought the unemployment rate to its lowest level in two years.Analysts pointed out that this disappointing report has reignited concerns about the labor market and may complicate the Federal Reserve's interest rate decisions, as policymakers need to seek a balance between weak employment and persistent inflation. As a result, market expectations for interest rate hikes quickly receded.Affected by this, U.S. stock index futures surged rapidly, with Nasdaq futures up 0.79% for the day, S&P 500 futures up 0.39%, and Dow futures up 0.27%. U.S. Treasury prices soared, with the yield on the 10-year U.S. Treasury currently down 4.29 basis points, reported at 4.627%; non-U.S. currencies generally rose, with the dollar against the yen briefly falling 80 points, reported at 157.72.At the same time, the U.S. Dollar Index DXY briefly fell nearly 30 points, reported at 99.67. Spot gold briefly rose about $40, reported at $4,351.43 per ounce.

Starknet announced that it has completed the quantum-resistant signature transfer test, where a wallet account using a quantum-resistant signature mechanism completed a real transfer on the Starknet mainnet, with a transaction fee of about 6 cents, and can be queried through the block explorer. This account is currently an experimental, unaudited version, mainly used for research testing. StarkWare stated that this transfer benefits from the design of the Starknet account model.Unlike most blockchains that fix the signature algorithm at the protocol layer, each account on Starknet is a smart contract that can autonomously define the accepted signature schemes, allowing users to upgrade their wallets from traditional elliptic curve signatures to quantum-resistant signatures without hard forks, asset migrations, or changing addresses. StarkWare pointed out that most blockchains face quantum computing risks because wallet signatures and underlying verification systems rely on elliptic curve cryptography. Once large-scale quantum computers appear, running Shor's algorithm could potentially break the related encryption systems. Currently, the Starknet ecosystem supports a quantum-resistant signature scheme based on Falcon-512, which is part of the NIST post-quantum cryptography standardization process, with relevant implementations promoted by ecosystem teams and organizations such as OpenZeppelin.

The Federal Security Service of the Russian Federation (FSB) conducted raids on 9 unregistered cryptocurrency trading service providers in Moscow, claiming they were suspected of transferring funds obtained from fraud abroad through cryptocurrency assets, and detained more than 20 employees at the Moscow International Business Center.The FSB stated that these exchanges converted stolen funds from Russian telephone scam victims into cryptocurrency and transferred them to accounts they referred to as Ukrainian processing parties. The operation was carried out jointly by the FSB and the Russian Ministry of Internal Affairs. The Russian Ministry of Internal Affairs has initiated a criminal investigation into large-scale fraud, which under Russian law can carry a maximum sentence of 10 years in prison. The FSB stated that it is continuing to identify victims and assess potential compensation.
