TL;DR: April’s attacks showed identity control planes, credential stores, and AI configuration files being targeted as privileged assets, while 5,372 CVEs included 439 identity-related weaknesses and 41 identity product flaws, according to Delinea Labs. The governance break is clear: systems that assume identity is only an authentication layer now fail when configuration files, service accounts, and AI agent settings become execution-level credentials.

NHIMG editorial — based on content published by Delinea: How April’s attacks redefined identity risk

By the numbers:

Questions worth separating out

Q: How should security teams govern AI configuration files that contain credentials?

A: Treat them as sensitive identity artifacts, not ordinary application files.

Q: Why do service account tokens increase lateral movement risk?

A: Because they authenticate as valid identities without human interaction and often carry access that persists beyond the original task.

Q: What breaks when identity governance stops at login events?

A: Teams lose visibility into the actions that happen after authentication, including token reuse, secret harvesting, and privilege escalation.

Practitioner guidance

  • Classify AI configuration files as governed identity artifacts Move MCP configs, agent settings, and token-bearing files into the same control set used for secrets, service accounts, and privileged credentials.
  • Review pipeline identities as part of access governance Inventory GitHub Actions, CI/CD tokens, and third-party build identities, then verify who can publish packages, trigger workflows, and access cloud secrets.
  • Reduce standing privilege on service accounts Scope cloud and Kubernetes service accounts to the minimum required resources, and rotate or revoke tokens that remain valid beyond the task window.

What's in the full report

Delinea's full threat report covers the operational detail this post intentionally leaves for the source:

  • The month-by-month attack chronology behind TeamPCP, including the supply chain handoff from initial token theft to package compromise.
  • The specific identity artifacts targeted in Claude MCP and Kiro environments, including how tokens and endpoints were exposed.
  • The incident detail behind the Drift and Omnistealer cases, including how cloud tokens and credential stores were abused in practice.
  • The CVE-by-CVE discussion of identity infrastructure flaws and the conditions that made exploitation possible.

Identity control plane exposure is now the real attack surface. The article shows attackers targeting trusted build paths, token stores, and configuration artifacts instead of only endpoint payloads. That shifts the governance problem from protecting systems at login to protecting the machinery that creates and distributes privilege. Practitioners should read this as a control-plane security problem, not a malware problem.

A few things that frame the scale:

  • 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to Ultimate Guide to NHIs.
  • Only 5.7% of organisations have full visibility into their service accounts, which is why unmanaged machine identities stay operational long after teams think they are contained.

A question worth separating out:

Q: Should organisations prioritise AI agent settings or service account cleanup first?

A: Start with whichever set of artifacts currently grants broader or less visible access, but do not separate them into different programmes. AI settings files, pipeline tokens, and service accounts can all become enterprise access paths, so the right approach is to govern them under one identity risk model with consistent inventory, classification, and review.
