yara-memory-hunting from dreadnode/capabilities is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use YARA against memory images to locate known malware, C2 frameworks, and custom IoCs. Covers rule selection, scoping (process vs whole image), false-positive control, and pivoting hits into structured findings.
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
# YARA Memory Hunting Maps to [MITRE ATT&CK T1059](https://attack.mitre.org/techniques/T1059/) (Command and Scripting Interpreter) and [T1027](https://attack.mitre.org/techniques/T1027/) (Obfuscated Files or Information) when classifying samples. For rule sources see Elastic [protections-artifacts](https://github.com/elastic/protections-artifacts), [YARA-Forge](https://yarahq.github.io/), and vendor reports. ## When to Use - You have IoCs (strings, byte patterns, config layouts) and want to confirm / scope - Triage surfaced a suspect process and you want to classify the family - Sweeping an image for commodity C2 frameworks (Cobalt Strike, Sliver, Brute Ratel, Metasploit, etc.) ## Scoping Decisions First | Goal | Scope | Rule style | |---|---|---| | "Is *this* process X?" | Single PID via `pid=N` | Specific, tight strings | | "Where in the image does X live?" | Whole image | Broader, paired-condition rules | | "Is there anything bad here at all?" | Whole image | Curated commodity-framework pack | Whole-image scans are slow and noisy. Use them when you don't yet have a suspect, then narrow to PIDs. ## Workflow ### 1. Pick the rule set …

How to install
mdr add dreadnode/capabilities/yara-memory-hunting@sha256:db3f7f5f39068a56The line at the top of this page pins the label git:20260504.2a64374, 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.
