Coinbase stated that it is optimizing the rule creation process in its anti-fraud system by integrating machine learning models with a rules engine, achieving more efficient risk management. It also proposed a dual-track strategy of "models responsible for long-term defense, rules responsible for rapid response," and built a unified framework to create a feedback loop between the two: rules are used to capture new types of fraud and train the model in reverse, thereby continuously enhancing overall defense capabilities.In terms of specific optimizations, Coinbase has transformed the previously manual rule creation process into a data-driven and automated recommendation system by restructuring data, automating schema evolution, and introducing notebook-based analytical tools, significantly improving efficiency. Among these improvements, the performance of rule backtesting has increased by more than 10 times, and the overall response time has been reduced from several days to a few hours. Additionally, the new system uses machine learning to recommend parameters, helping to reduce false positive rates while combating fraud and minimizing the impact on normal users. Coinbase indicated that the next step will be to advance event-driven automatic rule generation and explore the "one-click conversion" of efficient rules into model features, further moving towards an automated risk management system.

According to CoinDesk, monitoring by CertiK reveals that the Lazarus Group is conducting an attack operation named Mach-O Man targeting executives in the fintech and cryptocurrency industries. This operation utilizes ClickFix social engineering techniques, sending fake online meeting invitations to lure victims into pasting repair commands on their Mac terminals, thereby gaining access to company and financial systems.CertiK researcher Natalie Newson stated that the Lazarus Group has stolen over $500 million through attacks on Drift and KelpDAO in the past two weeks. Mach-O Man is a modular macOS malware toolkit developed by the Chollima division of the Lazarus Group, capable of automatically deleting itself after use to evade detection.Additionally, attackers have implemented this attack by hijacking DeFi project domain names and replacing them with fake Cloudflare messages.

According to monitoring by the blockchain security firm SlowMist, MistEye has received threat intelligence from the community indicating that a malware named "MacSync Stealer" (v1.1.2) is active and highly destructive. This malware targets macOS users, stealing sensitive data including cryptocurrency wallets, browser credentials, system keychains, and infrastructure keys (SSH/AWS/K8s).The malware uses a spoofed AppleScript system dialog for phishing and displays fake error messages stating "unsupported" after data leakage. It has immediately synchronized this IOC (Indicator of Compromise) to clients. Do not execute unverified macOS scripts and remain highly vigilant against unexpected system password prompts. If an attack is suspected, immediate remediation is required: change all infrastructure credentials (SSH/AWS/K8s), invalidate any exposed keychains, and quickly migrate cryptocurrency assets to a secure wallet.

According to Gate Ventures' latest weekly report, as the situation in the Middle East has temporarily eased and energy prices have fallen, global risk appetite has marginally improved, stock indices have reached new highs, and both the dollar and U.S. Treasury yields have declined. However, gold remains strong, indicating that while the market is flowing back into risk assets, the demand for safe-haven assets has not completely faded. Against this backdrop, the cryptocurrency market has seen a slight rebound overall, with BTC and ETH rising 4.3% and 3.3% respectively. ETF funds continue to see net inflows, but market sentiment remains cautious. Mainstream assets have performed relatively steadily with institutional support, while the recovery in the altcoin market remains limited.At the industry level, regulatory advancements and infrastructure development continue to deepen.

According to Jinshi reports, global markets significantly rebounded over the past week driven by expectations of easing tensions in the Middle East, but core uncertainties remain unresolved. Iran once announced the opening of the Strait of Hormuz, leading to a rapid decline in oil prices, a broad strengthening of risk assets, U.S. stocks reaching new highs, a weakening dollar, and gold approaching the $4900 mark. However, Iran subsequently signaled that it "is still under military control," combined with the U.S. maintaining sanctions against Iran, which has heightened market concerns about the volatility of the situation.On the macro level, the biggest variable next week will still be the progress of U.S.-Iran negotiations. U.S. President Trump stated that negotiations may advance over the weekend and warned that if an agreement is not reached by next Wednesday, the ceasefire could end, and there is a risk of renewed conflict; meanwhile, Iran's attitude towards negotiations remains cautious, especially with significant differences on key issues such as uranium enrichment. The market has currently shifted from "pricing in conflict escalation" to "pricing in a path to easing," but any sudden changes could still trigger sharp asset fluctuations.In terms of interest rate expectations, the decline in energy prices has alleviated inflationary pressures, and the market's expectations for a rate cut by the Federal Reserve this year have risen to about 60%.

According to GoPlus Security, a piece of malware named Infiniti Stealer is targeting Mac users' cryptocurrency wallets and sensitive credentials through a "ClickFix" social engineering attack method.The attackers forge a highly realistic Cloudflare CAPTCHA page to lure users into opening the terminal and manually pasting malicious commands. After executing the command, the script removes the macOS quarantine attribute and silently writes subsequent payloads to the /tmp directory. The final payload is a native macOS binary compiled with Nuitka, significantly increasing the difficulty of detection by security tools. Once deployed, Infiniti Stealer can steal Chromium / Firefox browser credentials, macOS Keychain, cryptocurrency wallets, and developer key files (such as .env files), and it has sandbox detection and delayed execution capabilities to evade tracking.

On the 26th of this month, the Urumqi Public Security Bureau High-tech Zone (New City District) reported that the Ergong Township Police Station discovered a suspected illegal repair site for electronic "mining machines" during a patrol in its jurisdiction.
