AI agents shift the question security teams ask about access

An analysis published by The Hacker News on 22 September 2026 argues that AI agents are changing how security teams should think about lateral movement, the process by which an attacker or a system moves from one resource to another inside an environment.

According to the piece, security teams have spent decades asking a single question about identities: does this account have too much access? That question underpins the familiar work of access reviews, least-privilege programmes and permission clean-ups. The article's contention is that the question is no longer sufficient once autonomous software is acting inside the same environment.

The harder question, the piece says, is not how much access an agent holds but which paths that agent can discover using the access it already has. That is a subtle but important reframing. An account can pass an access review and still sit at the start of a long chain of reachable systems, credentials and services that nobody has ever mapped, because nobody expected a single actor to try them all.

The article draws a distinction between three kinds of actor. A person given a task may try several approaches before finishing or giving up. A deterministic application, one whose behaviour is fixed in advance, follows only the flow its developer wrote; it cannot improvise a route the developer did not encode. An AI agent sits in neither category. The piece describes an agent as "relentless in its pursuit of done", meaning it will keep looking for a way to complete the objective it was given rather than stopping at the first obstacle.

That persistence is the crux of the argument. If an agent keeps searching for a route to completion, then the effective attack surface is not the set of actions a designer intended, but the set of actions the agent can find and successfully invoke. Permissions that looked harmless in isolation can combine into a path when something is willing to try every combination.

The article is an analysis rather than a disclosure. It does not, in the portion published, report a breach, name an affected vendor or describe a specific product flaw. Readers should treat its claims as an argument about how to model risk, not as evidence of an incident.

For defenders, the practical implication implied by the framing is that identity governance and path analysis are different disciplines. Reviewing whether an agent's credentials are appropriately scoped answers one question. Mapping what those credentials can reach, in sequence, answers another. The analysis suggests the second question is the one autonomous systems have made urgent.

The Agentic Times has not independently verified the arguments in the article, and the piece does not present incident data to support them.
