dma-attack-techniques SKILL.md skillA
dma-attack-techniques from gmh5225/awesome-game-security is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add gmh5225/awesome-game-security/dma-attack-techniques@git:20260926.7640fa9Pins git:20260926.7640fa9 in mdr.lock. Pin the fingerprint instead.

Analyze PCIe DMA threats, host-mediated memory acquisition, FPGA behavior, and IOMMU defenses. Use when the memory initiator or device boundary matters; use kernel security for host-only mechanisms.
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
# DMA attack techniques Identify the memory initiator, transport, required privilege, isolation boundary, and observable artifacts before classifying a technique as DMA. ## Topic routing - [Classification and threat model](references/classification-and-threat-model.md) for acquisition-path distinctions and attacker prerequisites. - [PCIe devices](references/pcie-devices.md) for TLPs, configuration space, programmable endpoints, and emulation limits. - [IOMMU and defense](references/iommu-and-defense.md) for VT-d/AMD-Vi, ACS, ATS/PASID, domain assignment, hypervisors, and trust anchors. - [IOMMU state verification](references/iommu-state-verification.md) for separating ACPI advertisement, Windows policy, live unit state, and per-requester coverage. - [Detection and forensics](references/detection-and-forensics.md) for defensive PCIe inventory, signal correlation, evidence capture, Thunderbolt/USB4, and memory access. - [Acquisition and transport](references/acquisition-and-transport.md), [assurance boundaries](references/assurance-boundaries.md), and [repository resources](references/repository-resources.md) for focused evidence and source selection. …

How to install
mdr add gmh5225/awesome-game-security/dma-attack-techniques@sha256:b6664c9e1bea81a1The line at the top of this page pins the label git:20260926.7640fa9, 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.
