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. Shortly after that blog post was published, Volexity discovered additional campaigns—this time from a third Chinese threat actor, tracked by Volexity under the alias UTA0565—that used the same chained exploits on September 3-4, 2026, while the vulnerabilities were still unpatched. Notably, this threat actor’s campaigns differed from previously documented attacks by using multiple fake websites to deceive victims.

On September 1, 2026, Volexity’s Network Security Monitoring service detected a spear-phishing campaign from a Chinese threat actor it tracks as UTA0560 targeting customers at multiple non-governmental organizations (NGOs). The emails contained a message encouraging the users to a click a link that led to the website of a US-based university. These links abused a reflected cross-site scripting (XSS) vulnerability on the website, redirecting recipients to threat-actor-controlled infrastructure hosting a multi-stage exploit chain that included a Google Chrome zero-day, CVE-2026-85046. Volexity analyzed its email telemetry and discovered that another Chinese threat actor it tracks as JungleBamboo (also known as APT31/Violet Typhoon/TA412) was also exploiting the same vulnerability chain against a different set of targets using different infrastructure and post-exploitation malware.
