gpo-abuse

gpo-abuse is a skill for Claude Code, Codex from blacklanternsecurity/red-run. It costs 95 tokens per session (4,512 once invoked), scanned B, original, GPL-3.0.

A penetration-testing skill for finding and abusing Active Directory Group Policy Objects, which are central rules that control Windows computers and users. It covers ways to use those rules for code execution, higher privileges, and movement between systems.

In plain words
What is it for?
Use it to enumerate Group Policy Objects and test immediate tasks, logon scripts, registry changes, and related tooling for privilege escalation or lateral movement.
Why use it?
Misconfigured or overly permissive Group Policy Objects can let an attacker run code or gain access as another user or computer. The skill helps assess that risk during an authorized security test.

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

gpo-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 10d 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.
