ags-ampa-sys-exp

ags-ampa-sys-exp is a skill for Claude Code, Codex from 1llu50ry/mcp-gamehacking. It costs 43 tokens per session (192 once invoked), scanned A, original, MIT.

A C/C++ exploit for a vulnerable Windows kernel driver named ampa.sys. Its insecure control interface can be abused to read or write kernel memory and run code with kernel-level access.

In plain words
What is it for?
It is for studying vulnerable-driver exploitation, including unsigned driver loading, privilege escalation, and anti-cheat bypass techniques.
Why use it?
It demonstrates how a driver bug can let an untrusted program gain powerful access to Windows. This helps researchers understand risks from vulnerable drivers.

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 A, and why

ags-ampa-sys-exp scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ampa.sys exp

Author: gmh5225 Source: mcp-gamehacking/skills/ags-ampa-sys-exp

Description

This project is an exploit for the ampa.sys vulnerable Windows kernel driver. It demonstrates how the driver's insecure IOCTL interface can be abused to gain arbitrary kernel read/write or code execution, enabling unsigned driver loading, process privilege escalation, or anti-cheat bypass. The C/C++ exploit automates the vulnerability trigger. It is aimed at BYOVD researchers studying vulnerable driver exploitation for kernel-level access.

Changes

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.

ags-ampa-sys-exp is a skill published in the GitHub repository 1llu50ry/mcp-gamehacking (344 stars, last pushed 2d ago), licensed MIT. It adds 43 tokens to every session and 192 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-23.
