Ghost Credentials Expose Cloud Systems to Hidden Identity Risks

July 28, 2026 · Dark Reading · Severity: MEDIUM

Ghost credentials, or dormant nonhuman identities such as service accounts, API keys, OAuth tokens, and machine-to-machine certificates, create significant security blind spots in cloud environments. These identities are often provisioned for automation and integrations, then forgotten as teams change and projects evolve, leaving them with excessive privileges that go unmonitored. Attackers increasingly target these stale credentials because they provide persistent access without triggering the alarms that would accompany human account abuse, particularly when the credentials belong to automated workflows that may already appear anomalous.

Key Takeaways

  • Ghost credentials are dormant nonhuman identities like service accounts and API keys that remain provisioned but unmonitored.
  • These identities accumulate excessive privileges over time as teams change and original provisioning context is lost.
  • Attackers preferentially target stale machine identities because they offer persistent access with low detection risk.
