5 Active Cyber Threats That Put US Enterprises at Risk in October 2026

In October 2026, multiple cyber threats targeted US enterprises using phishing kits, malware, and abuse of legitimate services. SkyW4lker, GeorgeGinx, and Mir0Auth are phishing campaigns exploiting Microsoft 365 device-code authentication to compromise corporate accounts without stealing passwords or bypassing MFA. Fake AI campaigns impersonated popular AI services to steal credentials via trojanized installers and fake event invitations. WKLP is a Python-based infostealer and RAT that disables Microsoft Defender, terminates security processes, and establishes persistent remote access on compromised systems. These threats leveraged trusted platforms like Adobe Shared Links and DocuSign to evade detection and increase success rates.
