Brash Exploit Crashes Chromium Browsers via Title API

⚠️ Security researcher Jose Pino disclosed "Brash", a severe flaw in the Blink rendering engine that can crash many Chromium-based browsers within 15–60 seconds via a single malicious URL. The root cause is missing rate limiting on the document.title API, enabling attackers to inject millions of DOM mutations per second and saturate the browser UI thread. Pino describes a three-phase technique — hash generation, burst injection, and UI-thread saturation — and warns the code can be time-triggered to act like a logic bomb. Affected products include Google Chrome, Microsoft Edge, Brave, Opera, Vivaldi, Arc, Dia, and some AI browser interfaces; Firefox and Safari are not vulnerable.

Chrome to warn before opening insecure HTTP sites in 2026

🔒 Google will enable Always Use Secure Connections by default in Chrome 154 (October 2026), prompting users before the first access to any public site that uses HTTP. This change promotes the existing opt-in HTTPS-First Mode to a default setting to better protect users from man-in-the-middle attacks and content tampering. Chrome will avoid repeated alerts for frequently visited insecure sites and offers options to restrict warnings to public sites or to include private intranets. Before the full rollout, Chrome 147 (April 2026) will enable the setting for over 1 billion users with Enhanced Safe Browsing to help identify sites that need migration.

Vidar Stealer 2.0 Rewritten in C with Multi-Threading

🛡️ Vidar Stealer 2.0 was released with a complete rewrite in C, multi-threaded data theft and stronger evasion, prompting warnings from security researchers about likely increased campaigns. The update reduces dependencies and footprint while spawning parallel worker threads to accelerate harvesting of browser, wallet, cloud and app credentials. It introduces extensive anti-analysis checks and a polymorphic builder to frustrate static detection. Notably, the malware injects into running browser processes to extract encryption keys from memory and bypass Chrome's App-Bound protections.

Cursor, Windsurf IDEs Exposed to 94+ Chromium Flaws

⚠️ The latest releases of Cursor and Windsurf IDEs embed outdated Chromium and V8 engines that contain at least 94 known, patched vulnerabilities. Ox Security researchers demonstrated a proof‑of‑concept exploiting CVE-2025-7656 (a Maglev JIT integer overflow) to crash Cursor, and warn that similar flaws could enable denial‑of‑service or arbitrary code execution in real attacks. Attack vectors include deeplinks, malicious extensions, poisoned README previews or documentation; the two IDEs together serve an estimated 1.8 million developers. Cursor dismissed the DoS finding as out of scope and Windsurf did not respond to inquiries.

North Korean Hackers Merge BeaverTail and OtterCookie

🔐 Cisco Talos reports that a North Korean-linked threat cluster has blended features of its BeaverTail and OtterCookie JavaScript malware families, with recent OtterCookie variants adding keylogging, screenshot capture, and clipboard monitoring. The intrusion chain observed involved a trojanized Node.js application called Chessfi and a malicious npm dependency published on August 20, 2025 that executed postinstall hooks to launch multi-stage payloads. Talos tied the activity to the Contagious Interview recruitment scam and highlighted continued modularization and abuse of legitimate open-source packages and public Git hosting to distribute malicious code.

Chrome to revoke notification access for inactive sites

🔕 Google is updating Chrome to automatically revoke website notification permissions for sites that haven't been visited recently on both desktop and Android. The feature targets sites that send a high volume of notifications while receiving very low user engagement — Google found under 1% of alerts generate interactions. Chrome will notify users when a permission is removed and makes it easy to restore access via Safety Check or by revisiting the site and opting back in. Users who prefer to keep persistent notifications can disable the automatic revocation entirely.

Google patches sixth Chrome zero-day exploited in 2025

🔒Google has released emergency security updates to address a high-severity Chrome zero-day, CVE-2025-10585, which a public exploit indicates is being used in the wild. The vulnerability is a type confusion weakness in Chrome's V8 JavaScript engine and was reported by Google's Threat Analysis Group. Google issued emergency Stable Desktop releases — Chrome 140.0.7339.185/.186 for Windows and macOS and 140.0.7339.185 for Linux — and recommends users update immediately via Chrome menu > Help > About Google Chrome and click 'Relaunch' once the update finishes.
