TL;DR: AI models face five threat patterns, including ransom, poisoning, tampering, breakout, and fugitive behavior, as organisations move AI into operational infrastructure and expose the identity trust model behind connected machines, according to CyberArk. The security question is no longer model integrity alone but whether every machine action is continuously authenticated and authorised in real time.
Editorial analysis by NHI Mgmt Group, based on content published by CyberArk: “The Emerging AI Threatscape: 5 New Risks to AI Models”.
Key questions
Q: How should security teams govern AI models that can call tools and access data?
A: Security teams should govern AI models as non-human identities with named owners, limited scope, short-lived credentials, and continuous authorization.
Q: Why do AI model threats create risk beyond model integrity?
A: Because the model is connected to other systems, integrity alone does not stop harmful behaviour from propagating.
Q: What are the signs that an AI model's guardrails are failing?
A: Look for unexpected tool use, new data destinations, output patterns that change without a known model update, and business actions that appear to have been triggered without normal human review.
Practitioner guidance
- Define model-to-system trust boundaries Inventory every data source, API, and workflow the model can reach, then document which actions remain allowed at runtime and which require denial by policy.
- Bind AI access to machine identity controls Issue distinct credentials for each model, pipeline, and environment so access can be revoked or constrained without affecting unrelated services.
- Separate training, inference, and downstream authorisation Prevent model outputs from automatically authorising business actions unless a separate policy layer validates the request and the context.
Bottom line: AI model risk is not limited to model integrity because connected systems can turn a manipulated model into a trusted execution path.

Machine identity is now the control plane for AI risk: Once AI systems are embedded in operations, the question is not only what the model knows but what it is allowed to touch. That shifts the security problem from isolated model protection to governed machine trust across data, tools, and downstream systems. The implication is that IAM and NHI teams must treat models as operational identities, not just workloads.
A few things that frame the scale:
- NHIs outnumber human identities by 25x to 50x in modern enterprises, according to the Ultimate Guide to NHIs.
- The 2025 Gartner Machine Identity Management in a Hybrid, Automated AI World Survey showed that 32% of organizations use mostly automated methods to manage credentials and only 1% use fully automated methods.
A question worth separating out:
Q: What should organisations do when AI systems need production access?
A: Treat AI access like any other privileged identity problem and define policy boundaries before granting production permissions. Specify allowed tools, data sources, and actions in enforceable rules, then log every policy decision. That keeps the AI governance discussion tied to access control rather than to abstract oversight language.
