Entra ID attack labs: what IAM teams should test now

TL;DR: Identity controls need repeatable attack-path validation, not just configuration review. EntraGoat is an open-source, deliberately vulnerable Entra ID lab built to let defenders practice privilege escalation, app ownership abuse, Graph API misuse, PIM chains, and certificate-based impersonation in a safe tenant, according to Semperis.

NHIMG editorial — based on content published by Semperis: EntraGoat, a deliberately vulnerable Entra ID environment for defender practice

By the numbers:

• Only 5.7% of organisations have full visibility into their service accounts.
• 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
• 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures.

Questions worth separating out

Q: What breaks when Entra ID privileges are only reviewed on paper?

A: Paper reviews miss the way ownership, Graph permissions, and eligible roles combine into actual escalation paths.

Q: Why do service principals create hidden privilege risk in Entra ID?

A: Service principals can carry powerful directory permissions even when they are not treated like human admins.

Q: How do security teams know whether PIM is actually reducing risk?

A: PIM is working only if eligible access cannot be combined with ownership, consent, or role-chaining to reach privileged state faster than governance expects.

Practitioner guidance

• Map escalation paths, not just entitlements Build test cases for ownership abuse, Graph permission misuse, PIM activation chains, and privileged role inheritance so you can see which identities can actually reach admin state.
• Validate service principal governance in a live tenant Review which service principals can modify directory objects, grant consent, or impersonate higher privilege, then compare that to what your access reviews currently cover.
• Exercise certificate lifecycle controls for privileged identities Test how quickly you can revoke, rotate, and detect misuse of certificate-backed access when impersonation is the attack path, not password theft.
