TL;DR: Agentic LLM systems tend to take the shortest path to success, which makes orphaned accounts, dormant users, stale service identities, and over-permissioned tokens disproportionately attractive attack routes, according to Orchid Security. That efficiency bias turns identity hygiene gaps into the easiest route to real access, especially where centralized IAM visibility is incomplete.
Editorial analysis by NHI Mgmt Group, based on content published by Orchid Security: “When “Lazy” LLMs Meet Identity Dark Matter”.
Key questions
Q: What breaks when orphaned or dormant identities are still able to authenticate?
A: They become the easiest path for a shortcut-seeking actor to reach real access, especially when the account bypasses normal approval or monitoring.
Q: Why do legacy auth paths and local accounts increase risk for agentic systems?
A: Because agents optimise for the fastest working route, and legacy auth often avoids SSO, MFA, and central logging.
Q: How do teams know whether identity hygiene is actually improving?
A: Look for fewer dormant accounts, fewer orphaned privileges, and shorter time-to-removal for leavers and role changes.
Practitioner guidance
- Map identity shortcuts across the application estate Inventory local accounts, dormant users, stale service identities, long-lived tokens, and any authentication path that bypasses the corporate IdP.
- Remove bypass paths that evade central monitoring Eliminate or tightly govern authentication routes that do not produce reliable SSO, MFA, or joinable audit telemetry.
- Correlate identity events to business context Join identity activity to application, project, environment, and data sensitivity so machine-speed abuse can be scoped without guesswork.
Bottom line: AI agents tend to exploit the easiest working identity path, which makes dormant, orphaned, and over-scoped credentials part of the attack surface.

Identity hygiene is now an attack-path control, not a housekeeping task. When agents are optimised for the shortest route to success, neglected identity artefacts become the path of least resistance. That means orphaned accounts, dormant users, stale service identities, and over-permissioned tokens are no longer just governance debt. They are the easiest way to convert machine efficiency into real access, so practitioners must treat them as attack surface.
A few things that frame the scale:
- 92% of cloud identities are over-permissioned and 62% are dormant.
A question worth separating out:
Q: What should teams do when an AI agent starts moving laterally?
A: Respond by hop type. Revoke or rescope the credential if the pivot is identity-driven, restrict egress if the connection is network-driven, and narrow tool permissions if the movement uses delegation. The containment action should match the path the agent used, not just the workload that produced the alert.
