New Cyber Threats Target US Enterprises with Fake AI Campaigns and Microsoft 365 Phishing

A new report from The Hacker News highlights active cyber threats impacting US businesses in October 2026. These threats include "Fake AI Campaigns" that exploit the adoption of AI by impersonating popular services like ChatGPT and Claude to steal credentials and compromise accounts. Additionally, the "SkyW4lker" phishing kit is actively exploiting Microsoft's legitimate device-code authentication to compromise corporate Microsoft 365 accounts without requiring password theft or MFA bypass. These campaigns pose significant risks of financial losses, data breaches, and operational disruption for enterprises.

Context
