Wintermute: Bitcoin faces its first test after breaking through, with $82,500 becoming a key observation level

Wintermute posted that, on the macro front, risk assets continued to rise last week. Even with the U.S. 10-year Treasury yield breaking above 5%, a high not seen since 2007, there was no significant risk-averse sentiment in the market. Crypto assets led the way, with altcoins rising approximately 5%, followed closely by BTC, and the Nasdaq also recorded gains, while long-term U.S. Treasuries performed the weakest.The report believes that oil prices will be a key factor influencing the interest rate hike expectations for October. Currently, oil transportation through the Strait of Hormuz remains significantly below pre-conflict levels, with Brent crude prices nearing $103 per barrel. If oil prices continue to stay around or above $100 per barrel, market expectations for another rate hike in October may remain high, at which point the core issue will shift to whether risk assets can absorb further rate hikes in the short term while bonds remain under pressure.In the crypto market, BTC last week first stood above the 50-week moving average on a weekly basis, with the current level of $82,500 being the upper boundary of the previous consolidation range, which is also a key position to watch this week; if this level can stabilize, it may become the foundation for the previous breakout; otherwise, a drop below this level will reignite concerns about the validity of the breakout. Meanwhile, BTC's market share has increased, the breadth of altcoin gains is at a relatively high level, and institutional options trading continues to increase with low Delta bullish options and call spreads being added for year-end positioning.

first_img Google disclosed the AI security agent PageBreak, which has identified over 500 vulnerabilities

The Google Product Security Team has disclosed an internal AI agent called PageBreak, used to test the security of its first-party web applications. This agent is built on Google's Gemini model and began a pilot program in November 2025, transitioning to a formal project in January 2026, with the goal of autonomously scaling vulnerability discovery and reducing manual input.Unlike common AI scanning tools, PageBreak hands over hypotheses to specialized validators after discovering suspicious defects, attempting actual exploitation in a real-time running copy of the application, and only reports once confirmed exploitable, with a false positive rate close to zero. Google claims that PageBreak has identified over 500 XSS vulnerabilities in its first-party web applications, which can be used to hijack login sessions, steal data, or impersonate users.Google stated that the security team has been overwhelmed in recent years by a large number of AI-generated vulnerability reports that appear reasonable but are not valid, making it a major challenge to distinguish real defects from hallucinations. When testing applications built using the next-generation high-assurance framework, PageBreak found only two vulnerabilities. The next step for Google is to integrate PageBreak with the automated remediation agent CodeMender, providing confirmed vulnerabilities with accompanying fixes.
