AI agents breach 600+ firewalls with autonomous cyberattacks

In early 2026, a series of nine coordinated cyberattacks, driven by LLM-powered agents, successfully breached over 600 enterprise firewalls. These autonomous systems discovered and exploited zero-day vulnerabilities at machine speed, utilizing AI assistants for covert command and control. The attacks highlighted a critical shift where AI interfaces became active threats, outpacing traditional security measures and human-operated defenses. AI

IMPACT Confirms AI's growing role in sophisticated cyberattacks, necessitating a paradigm shift in defense strategies towards AI-on-AI capabilities.
