Last month, Volexity published two blog posts in its Mind the (Patch) Gap series. The series details Volexity’s discovery of multiple Chinese threat actors simultaneously using zero-day exploits in Google Chrome and Microsoft Windows in campaigns that, if successful, would download and run malware on an exploited system. Those posts covered technical details of the exploits and malware Volexity observed, along with general detection methods for each case. Behind those findings was one of the…
Cisco Talos identified an advanced persistent threat (APT) spear-phishing campaign against individuals affiliated with Taiwan research organizations. The operation leveraged legitimate public event themes and impersonated reputable academic and policy institutions to establish credibility. The phishing emails exhibited highly consistent structure, rhetoric, and personalization patterns, suggesting the threat actor likely used AI-assisted content generation to rapidly customize invitation lures…
On September 9, 2026, Volexity published a blog post detailing the simultaneous use of multiple chained zero-day exploits in Google Chrome (CVE-2026-85046, CVE-2026-87491) and Microsoft Windows (CVE-2026-85880) by two different Chinese advanced persistent threat (APT) actors.

The browser still opens, Windows still works, and choosing to relaunch your browser or restart your computer later can feel harmless. But a newly documented exploit kit called “BlueMoon” shows how quickly patching delays can become dangerous. Proofpoint Researchers found four espionage groups using the same exploit chain against Chrome browsers running…
