Qué comprueba

Computes MULTI-HOP privilege-escalation chains to Tier-0 by transitively following control (GenericAll / WriteDacl / WriteOwner / AddMember) and group-membership edges — for example HelpDesk --[WriteDacl]--> CORP-Admins --[MemberOf]--> Domain Admins. Complements ADPATH-001 (single-hop) by chaining edges of arbitrary length and reporting the shortest path per principal. Chain DEPTH is bounded by ACL-collection coverage: with the current six-critical-object collection most chains are one hop, so this check is typically clean today; the full-domain ACL collector (roadmap, live-gated) populates control edges over arbitrary objects and unlocks deep low-privilege-to-Domain-Admin chains. The engine itself chains arbitrary depth (BFS shortest-path, cycle-safe).

Valor recomendado

No transitive control chain leads a non-privileged principal to Tier-0.

Remediación

For each chain, break the weakest link: remove the attacker-controllable ACE at the first hop (the non-privileged principal's control over the next object in the chain), or remove the nested group from the Tier-0 group. Re-run to confirm the chain is severed.
