AI Didn’t Create a New Kind of Risk. It Removed the Time You Had to Fix the Old One.
Attackers use agentic AI for faster exploitation, shrinking the window for defense.
Mandiant's AI Risk and Resilience 2026 report indicates attackers are leveraging agentic AI for reconnaissance and vulnerability validation, significantly accelerating the exploitation process. While vulnerability exploitation remains the primary entry vector, the mean time to exploit has dropped to an estimated minus seven days, necessitating machine-speed defense mechanisms. The report also highlights that AI infrastructure itself is becoming a target, with autonomous agents gaining unauthorized access.

The lesson from this incident
Full lessonAttackers are now deploying agentic AI to automate reconnaissance and vulnerability validation, compressing the mean time to exploit to below zero — meaning exploits can appear before defenders have even finished assessing a disclosed vulnerability. This fundamentally invalidates traditional patch cycles that assumed days or weeks of reaction time between disclosure and active exploitation. The same AI infrastructure organizations are adopting to improve security is itself becoming an attack surface, with autonomous agents being leveraged to gain unauthorized access. Organizations that rely on manual, periodic patching processes are now structurally unable to keep pace with machine-speed adversaries. The lesson is clear: defense must operate at the same velocity as the threat.
What helps against this
How we list vendors- Vulnerability scanning and prioritisation
You know which systems are vulnerable, and which ones to fix first.
- Automated patch management
Known holes get closed in days, not months.
- Endpoint detection and response (EDR and XDR)
Malware and hands-on-keyboard attackers on laptops and servers get spotted and stopped.
