DAMP

The Discretionary ACL Modification Project: Persistence Through Host-based Security Descriptor Modification.

This project contains several files that implement host-based security descriptor "backdoors" that facilitate the abuse of various remotely accessible services for arbitrary trustees/security principals.

tl;dr - this grants users/groups (local, domain, or 'well-known' like 'Everyone') of an attacker's choosing the ability to perform specific administrative actions on a modified host without needing membership in the local administrators group.

Note: to implement these backdoors, you need the right to change the security descriptor information for the targeted service, which in stock configurations nearly always means membership in the local administrators group.
