The French Minister of Finance confirmed that hackers breached the French Public Finance Directorate system at the end of June and stole personal and corporate taxpayer data. According to the platform FrenchBreaches, which tracks cyberattacks in France, this incident affected approximately 678,437 people, equivalent to about 1% of the French population, but the exact number is still under investigation and has not been finally confirmed.The leaked data reportedly includes sensitive information such as names, birth dates, home addresses, phone numbers, email addresses, tax identification information, and income data. Among them, nearly 27,000 individuals had tax incomes of at least 100,000 euros, 386 exceeded 1 million euros, and another 8 exceeded 10 million euros. Reports indicate that the database has been sold on the dark web market for thousands of euros. The attackers, calling themselves ZeroBytes, claimed they extracted the relevant records using an internal search tool, which was only discovered later when access was cut off.This incident has raised concerns in the cryptocurrency industry, as there has been a noticeable increase in "wrench attack" violent robbery incidents targeting cryptocurrency holders in France in recent years. If high-income individuals' addresses and contact information are leaked, it could provide criminals with a more precise target list.

Bitcoin News posted on the X platform that the 256 Foundation has launched the 256 Red Team security project, which audits ASIC miner firmware through reverse engineering, real-time traffic capture, and reconciliation by share level. The team stated that 41 issue reports have been submitted regarding the original Bitmain firmware as well as third-party firmware such as LuxOS, VNISH, and Braiins OS.Identified issues include unauthenticated factory APIs, paths that allow root access, default credentials, built-in vendor SSH keys, and updaters that cannot verify installed content. After reverse engineering the Bitmain miner daemon and checking real-time connections, researchers reported that no evidence of hash power hijacking, remote kill switches, or hidden beacons was found in the original Bitmain firmware; the related risks are mainly concentrated in third-party "optimized" firmware.Researchers have submitted 3 responsible disclosures to VNISH, Luxor, and Braiins, granting each party 30 days to respond before public disclosure. MicroBT, Canaan, Auradine, Bitdeer, and ePIC will undergo follow-up audits.

Solstice Finance launches strcUSX on Solana, splitting the dividend income and price risk of the Nasdaq-listed company Strategy's Series A perpetual preferred stock STRC into two types of tokens: senior and junior. The annual dividend yield of STRC is 12%.The senior tranche SR-strcUSX targets an annual yield of approximately 7%, with priority for dividend income and principal repayment; the junior tranche JR-strcUSX bears the first loss from market value fluctuations and receives the remaining income after payments to the senior tranche, targeting an annual yield of over 20%. Users can deposit USX into the strcUSX vault to receive tokens corresponding to the risk level. Both types of tokens are native assets on Solana, tradable, usable as collateral, or accessible for DeFi applications.Solstice Finance will also integrate USX into Zebec Network's payroll infrastructure, which processes over $500 million in payroll annually and has over 50,000 monthly active users.

Bitcoin News posted on the X platform that after two weeks of using cutting-edge AI to scan almost the entire Bitcoin open-source ecosystem for vulnerabilities, Bitcoin Red Team member @callebtc stated, "The easily discoverable vulnerabilities have been addressed," and maintainers are verifying "a large number" of serious and high-risk vulnerabilities.@callebtc indicated that the main findings include: decades of accumulated open-source technical debt are being exposed alongside AI capabilities that can discover vulnerabilities at speeds and scales unattainable by human researchers; Lightning seems particularly vulnerable, with its complexity meaning its security status is "worse than average"; unmaintained Bitcoin projects should be considered vulnerable until their security is confirmed.Projects that began building AI security and auditing processes months ago are now in a completely different position compared to those that have been waiting until now. The Bitcoin Red Team has now completed a foundational scan of almost the entire Bitcoin open-source ecosystem. Easily discoverable vulnerabilities have mostly been addressed, but as AI capabilities improve, external red team testing may need to continue indefinitely. Despite discovering and reporting "a large number" of real serious and high-risk vulnerabilities, @callebtc believes this process will ultimately make Bitcoin stronger. The same AI security review will soon expand to areas far beyond Bitcoin.

A study published at USENIX Security '26 shows that researchers identified 65,340 high-risk crypto addresses associated with abuse on Ethereum and BNB Chain, with associated native token losses amounting to 126,982.94 ETH and 17,726.7 BNB.The study estimates that the total losses associated with these addresses exceed $574.8 million, with two newly described active attack vectors directly leading to approximately $15.7 million in losses (accounting for 2.7%).The first type involves misuse of contract accounts and exploitation of deterministic contract addresses; the second type uses EIP-7702 to delegate accounts exposing keys to malicious code for direct fund transfers. The research team extracted over 16.3 million deduplicated private keys by mining 63,004 GitHub repositories from January 2015 to May 2025, with an overall detection accuracy of 99.11%.

The U.S. Commodity Futures Trading Commission (CFTC) requires the prediction market platform Kalshi to continue operating its exchange, executing in accordance with normal business practices and the core principles of the Commodity Exchange Act. The CFTC previously determined that New York's attempt to prevent the platform's operation constitutes a market emergency.The CFTC stated that forcibly liquidating a Bitcoin price position that extends until the end of 2026 could trigger traders to simultaneously unwind Bitcoin and other asset positions, exposing arbitrageurs holding opposite positions to one-sided risk. The order also enumerates contracts such as federal funds rates, traffic in the Strait of Hormuz, and the timing of economic recessions. A ruling signed by Judge Vernon D. Oliver of the U.S. District Court for the District of Connecticut concluded that Kalshi's sports contracts do not constitute swaps; even if they were swaps, federal law would not take precedence over Connecticut's gambling regulations.

According to Cointelegraph, Ravencoin was attacked due to a consensus vulnerability, causing the price to drop to a historical low of $0.002754, down about 22% from the 24-hour high. The vulnerability allowed weak nodes to accept invalid blocks, with the first known exploit occurring at block height 4,487,776.Mining pools 2Miners and RavenMiner, which control the majority of the network's hash power, are building a competing chain that excludes the affected branch. If this chain becomes dominant, the network may undergo a chain reorganization of about three days, and transactions confirmed after block 4,487,775 may be reversed. Ravencoin has advised exchanges to suspend deposits and withdrawals until the chain stabilizes, and Upbit and Bitget have already suspended RVN transfers.

Wintermute released a market update indicating that the U.S. non-farm payrolls unexpectedly decreased by 23,000 in July, significantly weaker than market expectations, leading to a drop in September rate hike expectations from 55% to 40%, and driving a broad rebound in risk assets.Gold led the gains, with the Nasdaq, S&P 500, Bitcoin, and altcoins generally rising, while Brent crude oil fell by 6.85%.

Trader Ansem (@blknoiz06) posted on the X platform stating that currently, there are tens of billions of dollars in stablecoin funds on-chain waiting to re-enter the risk asset market. Ansem believes that in the coming weeks, market participants will gradually realize that mainstream crypto assets (Majors) do not need to reach new historical highs, and capital rotation may occur earlier.He stated that as stablecoin funds flow back into the risk asset market, the market may welcome a stronger upward trend.

Analyst Murphy stated that the BTC supply concentration has risen to 14.8%, approaching the high-risk zone of 15%. The risk here refers to volatility rather than the direction of price changes; the supply concentration itself does not indicate direction.Murphy noted that based on historical data, a pattern has been observed: when the supply concentration curve begins to turn downward, if the BTC price has been rising beforehand, the probability of continuing to rise afterward is greater; conversely, if it has been falling, the probability of continuing to fall is greater. However, the supply concentration is still on the rise and has not yet turned, so it is currently impossible to determine which direction the probability of movement will be greater after the turn. What can be confirmed is that risk is accumulating and volatility is brewing.

Crypto analyst Murphy stated that the concentration of Bitcoin chips has risen to 14.8%, approaching a historically high-risk area. The concentration of chips itself cannot determine the future direction of BTC prices, but historical data shows that when the curve begins to turn, if BTC prices have risen previously, the probability of continuing to rise is greater; conversely, the probability of continuing to fall is greater.Currently, this indicator is still in an upward phase, so it is temporarily impossible to determine the direction of the next round of fluctuations. However, market data shows that as the concentration of chips continues to increase, potential volatility risks are accumulating, and the BTC market may face larger price changes.

ARK Invest stated that despite the latest U.S. employment data appearing weak, the overall economic situation is not as pessimistic as it seems. Cathie Wood mentioned that the U.S. federal deficit as a percentage of Gross Domestic Product (GDP) is currently 5.6%, and if productivity and technology adoption continue to improve, it may approach 5% by the end of the year.

Bitcoin developer Kevin Loaec warned that if a Bitcoin fork related to the controversial proposal BIP-110 occurs this weekend, holders may face the risk of real BTC being transferred when selling forked chain tokens.The proposed Bitcoin fork is associated with the controversial BIP-110 proposal and may generate duplicate balances on two chains, leading holders to attempt to sell seemingly free forked coins.Since both chains initially accept the same transactions, selling forked coins could trigger a replay attack, simultaneously spending real Bitcoin from the seller's main chain. Developers stated that there is a lack of built-in replay protection at least until early September, and non-professional users should avoid transferring Bitcoin during the potential fork.

The U.S. Commodity Futures Trading Commission (CFTC) has issued a warning about the risks of American odds in prediction markets.

The prediction market platform Kalshi announced the launch of the AI tool Blanket, aimed at helping small businesses hedge operational risks related to weather, energy prices, tariffs, elections, and more using event contracts.Blanket was developed by independent fintech entrepreneur Lauris Zminsky, based on Kalshi's CFTC-regulated prediction market operations, but it is not an internal product of Kalshi. The tool does not directly execute trades or handle funds, but instead analyzes the risks faced by businesses through AI and recommends Kalshi event contracts that can be used for hedging.

Bitcoin's recent volatility has nearly disappeared, but market risks have not been alleviated. Data shows that there has been no outflow of funds from the spot Bitcoin ETF, with a cumulative net inflow of approximately $754 million. However, the price of Bitcoin remains around $64,700, while the options market is focused on downside protection near $62,000 and $63,000.Market signals are showing divergence: on one hand, demand for spot ETFs is rebounding; on the other hand, derivatives traders are positioning themselves for a potential pullback, especially on the eve of the release of the latest U.S. employment data. However, from the overall position structure, the market still leans bullish. Bitcoin call options account for about 60.7% of total open contracts, indicating that investors' long-term expectations remain positive, although recent trading has been more concentrated on short-term risk hedging. Meanwhile, the cost of volatility protection is at a low level. The DVOL index from Deribit, which reflects the expected volatility of Bitcoin over the next 30 days, is currently around 35, a significant drop from the high of 90 earlier this year, indicating that the market believes the likelihood of significant volatility in the short term is limited.However, U.S. macro data could disrupt this balance. The market expects that non-farm payrolls in the U.S. will increase by about 97,500 in July, up from 57,000 in June, with the unemployment rate expected to remain at 4.2%. If the employment data is stronger than expected, it could push U.S. Treasury yields higher and strengthen expectations for Federal Reserve interest rate hikes; if the data is weak, it could lower yields but also exacerbate concerns about slowing economic growth. Currently, the Bitcoin market shows a pattern of "ETF funds supporting spot, options market guarding against declines," and potential risks in a low-volatility environment still need to be monitored. In a market with low participation and insufficient liquidity, even small changes in supply or demand could lead to significant price fluctuations.

Bank of America strategists indicate that investor bullish sentiment has reached extreme levels, suggesting a reduction in exposure to risk assets. The Bull-Bear Index rose from 9.4 to 9.7, marking the highest level since 2021. The rise in the stock market, inflows into high-yield bond funds, and narrowing credit spreads are the reasons for the optimistic sentiment.Hartnett stated that we are still in the summer "withdrawal/rotation" phase, advising investors to reduce allocations to risk assets and shift towards defensive assets and the dollar.
