REA prompt pack: DMA & hardware-assisted cheat research (defensive) (4 ready-to-paste prompts). Use when doing reverse-engineering investigation of dma & hardware-assisted cheat research (defensive) with REA (rea.tools) via an AI coding agent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# REAP — 13. DMA & hardware-assisted cheat research (defensive) Part of REAP (REA Investigation Prompts). Replace everything in <angle brackets>; keep each request focused on one feature. Demand file/function/address evidence and separate facts from hypotheses. > DMA attacks are a real anti-cheat and platform-security problem. Use these > to **study how detection works** and to **harden your own product/lab** — > on machines you own, offline targets, or with vendor authorization. Reading > another machine's memory over PCIe without authorization is illegal in most > jurisdictions. ### How DMA memory access works on a target platform ```text Use REA on <anti-cheat driver / DMA-protection firmware (e.g. Thunderbolt security, IOMMU/VT-d config)> in my lab. Explain, with function/address evidence: how the platform restricts external PCIe memory reads (IOMMU mappings, Thunderbolt ACLs, kernel DMA protection), what the anti-cheat enumerates to spot a DMA device (PCIe topology, BAR regions, unknown root ports, timing anomalies), and which checks are load-bearing versus cosmetic. ``` ### Analyze a DMA-cheat toolchain sample (malware-style) ```text …

How to install
mdr add joasasantos/rea-prompts/reap-13-dma-and-hardware-assisted-cheat-research-defensive@sha256:69b5e7bdd42e0fc0The line at the top of this page pins the label git:20261025.9bd45a8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
