TL;DR:
AI is expanding attacker capabilities, but familiar vulnerabilities and control failures still drive many breaches. Security leaders need stronger fundamentals alongside AI-specific defenses.

What you need to know

  • The change: AI is appearing across more attack techniques, but vulnerability exploitation remains a leading path into organizations.
  • Who is affected: CISOs, CIOs, security operations leaders, AI teams, and enterprise risk leaders.
  • Why it matters: Current evidence supports neither replacing cybersecurity fundamentals with AI security nor assuming traditional controls cover every AI-related risk.
  • What to do first: Review whether foundational security coverage includes the identities, SaaS integrations, credentials, infrastructure, and AI systems relevant to your environment.
  • Key trigger: NIST is developing a Cyber AI Profile that separately addresses securing AI systems, AI-enabled cyber defense, and AI-enabled attacks. (csrc.nist.gov)
