Cyber threat intelligence production — the intelligence cycle, IOC extraction/normalization/enrichment,.
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
# Threat Intelligence & CTI ## Evidence contract ### Script output contract (3.2) `cti_processor.py` accepts text and produces extraction candidates. Its `extraction_confidence` describes recognition only; `maliciousness_confidence` is null until independently assessed. `detection_readiness` is `needs-review`. STIX exports are neutral cyber-observable objects with TLP 2.0 statement markings; MISP-style exports keep `to_ids` false. Unsupported STIX types are explicitly listed in bundle metadata. Preserve the full plugin checkout for shared utilities. Separate **observed**, **inferred**, and **unverified** conclusions. For each finding, record the source/artifact reference, SHA-256 when a file is available, collection time, validation performed, limitations, and next verification step. Extraction confidence is not maliciousness confidence; unknown maliciousness stays unknown. Generated queries/rules are unverified until tested against the intended backend and labeled positive/negative fixtures. Never present simulated results as live evidence. Select an execution mode: `offline` (default for supplied files), `passive` …

How to install
mdr add masriyan/claude-code-cybersecurity-skill/21-threat-intelligence@sha256:2bb102b1a10b79bbThe line at the top of this page pins the label v3.3.0, 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.
