Map service-account impersonation and token-generation paths that let a principal act as a more-privileged identity: a role granting impersonation or token creation on a service account, an actAs or token-creator permission that chains one identity into another, and a sequence of such grants that reaches a highly privileged account from a low-privileged start. Covers cloud service-account impersonation, short-lived-token generation, and the transitive graph where each impersonation grant is an…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mapping service-account impersonation chains: when one identity can become another Cloud identity models let a principal act as a service account through impersonation or short-lived-token generation, and each such grant is an edge in a graph: whoever holds it can become the target identity and inherit its permissions. Individually these grants look benign, a deployment principal impersonating a deploy account, an automation user minting a token for a job account. The risk is transitive. If the target account can itself impersonate a third, and that a fourth, a low-privileged starting principal can walk the chain into an administrative identity no single grant intended. You find these by treating impersonation and token-creator grants as edges and mapping where a starting principal can reach. ## When to use - Principals can impersonate service accounts or generate short-lived tokens for them. - An actAs, token-creator, or equivalent grant lets one identity act as another. - You need to know the transitive reach of a starting principal through chained impersonation. ## Scope check …

How to install
mdr add unboundcompute/security-agent-skills/mapping-service-account-impersonation-chains@sha256:afd95447d2e07ea3The line at the top of this page pins the label git:20260827.b5f41a4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
