acl-abuse

acl-abuse is a skill for Claude Code, Codex from blacklanternsecurity/red-run. It costs 62 tokens per session (5,548 once invoked), scanned B, original, GPL-3.0.

A set of techniques for abusing permissions in Microsoft Active Directory, the system many organisations use to manage users, computers and access. It covers ways to gain higher privileges, control accounts and maintain access.

In plain words
What is it for?
For assessing Active Directory permissions, including rights such as GenericAll, GenericWrite, WriteDACL and WriteOwner, as well as Kerberos, shadow credentials and AdminSDHolder persistence.
Why use it?
It helps identify when overly broad directory permissions let an attacker take control of accounts or systems. It also explains several paths from a limited account to wider domain access.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

acl-abuse scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A mod that escalates privileges can change anything on the machine, not only the project.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
