Protecting organizations from AI-assisted executive impersonation and invoice fraud

Microsoft tracked a campaign of over one million AI-crafted CEO-impersonation emails seeking ~$50,000 ACH payments with fabricated ServiceNow invoices.

Between August 3 and 5, Microsoft detected a campaign of more than one million fraud emails, 87.7% of them targeting US enterprise users, sent through multiple third-party email delivery service accounts. The actor impersonated CEOs, CFOs, and presidents of targeted companies, urging accounts payable staff to process an ACH payment of nearly $50,000. Lures layered executive impersonation, lookalike domains, a fabricated ServiceNow 'Annual Subscription' invoice personalized to the recipient, and forged forwarded email threads; Microsoft found no evidence ServiceNow or the referenced executives were compromised. Microsoft observed indicators consistent with generative AI-assisted template creation, while leftover inconsistencies such as missing forwarding headers and mismatched display names gave defenders detection cues.

New 'BlueMoon' kit exploited Windows and Chrome zero-day flaws

Multiple China-linked espionage groups share the BlueMoon exploit kit chaining Chrome V8 zero-days and a Windows ALPC LPE to deploy backdoors.

Proofpoint and Volexity report that multiple espionage clusters share the BlueMoon exploit kit, chaining Chrome V8 zero-days CVE-2026-85046 and CVE-2026-87491 with the Windows ALPC local privilege escalation CVE-2026-85880. Proofpoint observed spearphishing use since August 28 by JungleBamboo (APT31), while Volexity saw UTA0560 targeting NGOs from September 1; UNK_LateNight hit US aerospace/defense with ShadowPad and UNK_DoubleCheck targeted Vietnamese manufacturers. The kit's maintainers reverse-engineer public Chromium fixes before stable Chrome releases, and Proofpoint suspects the ALPC exploit has existed since 2025.
