exploiting-constrained-delegation-abuse

The skill is internally coherent and not deceptive, but it is a high-risk offensive-security skill for AI agents. It enables credential use, ticket abuse, lateral movement, and privilege escalation with third-party tooling, so it should be classified as suspicious/high risk rather than benign or confirmed malware.

The fragment is a dual-use Active Directory assessment tool. Its enumeration behavior is consistent with defensive auditing, but check_s4u_abuse() contains explicit Kerberos delegation abuse functionality using passwords or hashes and administrator impersonation. That function is not called by the provided main() path, so the fragment does not autonomously perform the abuse. No evidence of malware, data exfiltration, persistence, or obfuscation is present. Use should be restricted to authorized environments, and secrets should not be passed via process arguments where avoidable.

This is security-focused documentation for enumerating and abusing Kerberos delegation, including constrained delegation and RBCD. The examples are highly actionable and could facilitate unauthorized privilege escalation if executed in a real domain, but the fragment contains no executable implementation or autonomous malicious behavior. It should be treated as dual-use offensive security content and used only in authorized environments.
