Google patched two Chrome flaws. Four spy groups already used them.
SecurityWeek reports that Proofpoint found an exploit kit called BlueMoon chaining two Google Chrome vulnerabilities with an Microsoft Windows privilege-escalation flaw.
The Chrome bugs, CVE-2026-85046 and CVE-2026-87491, sit in the V8 JavaScript and WebAssembly engine. They were patched on 3 September and 8 September. The Windows bug, CVE-2026-85880, is an ALPC privilege escalation fixed in the September 2026 Patch Tuesday.
Proofpoint says Violet Typhoon, also tracked as APT31, first deployed BlueMoon on 28 August against US non-governmental organisations. Mining companies and commodity traders were also targeted.
UNK_LateNight targeted US aerospace companies on 2 September. UNK_DoubleCheck targeted a Vietnamese manufacturing organisation. On 3 September, UNK_QuietRacket targeted financial organisations. Government and consulting organisations in Indonesia and Singapore were also targeted.
Proofpoint says: "It is currently unknown how multiple distinct threat actors obtained access to the exploit kit." The firm adds that artefacts suggest its creators might have used AI, though none confirms it.
