Major Cyber Attacks in August 2026: US and EU Businesses Hit by Session Hijacking, Remote Access, and Insider Risk

August 2026 saw multiple coordinated and opportunistic threats against US and EU organizations: a US-first RMM phishing campaign using legitimate remote-management tools to gain hands-on access across 46 countries; Mirage2FA and 3DBlast phishing toolkits that intercepted Microsoft 365/Google authentication and active sessions (over 4,000 US victims reported for Mirage2FA); SnakeBiteAgent, a .NET RAT delivering credential theft, keylogging, and remote control; and a Famous Chollima (Lazarus-linked) operation that obtained legitimate access through fake hiring and identity fraud—collectively demonstrating session hijacking, OAuth/device-code abuse, persistent access, and insider-risk vectors that increase SOC detection and containment challenges.
