lookup-crowdstrike

lookup-crowdstrike is a skill for Claude Code, Codex from Liberty91LTD/cti-skills. It costs 173 tokens per session (2,516 once invoked), scanned A, original, MIT.

A read-only connector to CrowdStrike Falcon Intelligence, a threat-intelligence service for investigating suspicious digital indicators and cyber adversaries. It retrieves information about IP addresses, domains, file hashes, URLs, threat actors, attack techniques, and intelligence reports.

In plain words
What is it for?
Use it to look up indicator reputation, linked actors and malware, search actors by origin or target industry, review MITRE ATT&CK techniques, and find finished reports.
Why use it?
It gathers CrowdStrike's existing intelligence in one place when you need to check whether an indicator or attacker is associated with malicious activity.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 tools/clis/crowdstrike.py indicator <value> [--limit N] [--include-deleted].

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lookup-crowdstrike scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.

lookup-crowdstrike

Queries the CrowdStrike Falcon Intelligence (Intel) API for indicator (IOC) reputation, threat-actor (adversary) profiles, actor search by origin/target, MITRE ATT&CK technique coverage, and finished intelligence reports. Retrieval only — do not interpret, assess, or conclude. The invoking skill or agent reasons about the result.

When to invoke

  • User asks to look up an IP / domain / hash / URL and CrowdStrike credentials are configured — return CrowdStrike's malicious-confidence, linked actors, malware families, and report references alongside the other lookups
  • User asks for the latest / recent malicious IOCs, a CrowdStrike indicator feed, or "what's CrowdStrike seeing lately" → indicators --malicious (browse/sweep, newest-first; filter by type/actor/malware/recency)
  • User asks "what TTPs / techniques does use?" → ttps <actor> (MITRE ATT&CK mapping)
  • User asks "which threat actors operate from ?" / "who targets ?" → actors --origin <c> / --target-industry <i>
  • User asks to profile a named adversary (Charming Kitten, Mustang Panda, Cozy Bear, …) → actor <name>
  • User wants the latest finished reporting on an actor or topic → reports --actor <name> --latest or reports --search "<topic>"
  • /threat-actor-profiling or a regional espionage cell wants vendor-authoritative attribution, origins, motivations, and capability
  • Need to download a specific intel report PDF by ID → reports --pdf <id>

How to invoke

One CLI: a Python wrapper around the official crowdstrike-falconpy SDK. Self-bootstraps a private venv at tools/clis/.venv-crowdstrike/ on first run; no global install. The SDK exchanges your client id + secret for an OAuth2 bearer token at /oauth2/token automatically.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
