Rapid static assessment, classification, and prioritization of malware samples. Use for the first look at any unknown file — hashes, file type, packing, imports, strings, initial IOCs, threat level, and the decision on which deep-analysis phase comes next. Claude runs the static tooling on the host itself; the sample is never executed.

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

# Malware Triage

First phase for every sample. You run static tools on the host, interpret the output, classify the sample, and decide the next phase. Target: 5-15 minutes per sample.

## Execution Model

- **You run the commands.** You have Bash. Execute every command in this skill yourself and interpret the output. Do not ask the user to run tools or paste results unless a tool is missing and cannot be installed.
- **Locate skill files.** Scripts and reference files ship in this skill's directory. Set `R="${CLAUDE_PLUGIN_ROOT:-<dir containing this SKILL.md>}"` once (when installed as a plugin `$CLAUDE_PLUGIN_ROOT` is set; otherwise it is this skill folder). Your working directory is the user's analysis workspace, so prefix every script path below with `$R`, e.g. `python3 "$R"/scripts/ioc_extract.py`.
- **Never execute the sample.** Only static tools touch it: `file`, `strings`, `pe_info.py`, `upx -d`, `7z l`, hashing. No `chmod +x`, no `wine`, no `./sample`.
- **Never upload the sample** to any service without explicit consent. Hash lookups are fine; file uploads are not.

How to install

The exact contents, by fingerprint
mdr add gl0bal01/malware-analysis-claude-skills/malware-triage@sha256:0b17fefe250112c8

The line at the top of this page pins the label git:20260905.e1d9a1a, 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.
