Chinese espionage groups swarm to exploit triple-link chain of zero-days

Four China-aligned espionage groups, starting with TA412/APT31, chained zero-days CVE-2026-85046, CVE-2026-87491 and CVE-2026-85880 to spy on targets since late August.

TA412 (Violet Typhoon/APT31) began exploiting the BlueMoon chain on Aug. 28, followed by UNK_LateNight (US aerospace, Sept. 2), UNK_DoubleCheck (Vietnamese manufacturing via a compromised Southeast Asian government account) and UNK_QuietRacket (Indonesia and Singapore government, consulting and finance, Sept. 3). The chain pairs Chromium JavaScript engine RCE flaws CVE-2026-85046 and CVE-2026-87491 with the Windows ALPC privilege-escalation zero-day CVE-2026-85880, enabling sandbox escape and system privileges. Delivery used phishing links installing a fake Google Gemini browser extension that surveilled browser activity and stole credentials; Proofpoint directly observed fewer than 20 organizations but expects wider proliferation as the kit spreads.
