lookup-ransomwarelive

lookup-ransomwarelive is a skill for Claude Code, Codex from Liberty91LTD/cti-skills. It costs 119 tokens per session (2,057 once invoked), scanned A, original, MIT.

A lookup tool for ransomware.live, a service that tracks claims posted by ransomware groups on their leak sites. It retrieves information about alleged victims, groups, indicators, detection rules, ransom notes, negotiations, and incident-response contacts.

In plain words
What is it for?
Use it to check an organisation or domain for claimed ransomware activity, study a ransomware group, gather indicators or YARA detection rules, or find country-level and sector-level victim claims.
Why use it?
It collects ransomware-related information in one place while making clear that a leak-site claim is not proof that a breach occurred.

Skill for Claude CodeCodex

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/ransomwarelive.py validate # check the API key.

Good fit Use it to check an organisation or domain for claimed ransomware activity, study a ransomware group, gather indicators or YARA detection rules, or find country-level and sector-level victim claims.

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-ransomwarelive 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 12d 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.

lookup-ransomwarelive

Queries ransomware.live's PRO API for victim claims, group profiles, IOCs, YARA rules, ransom notes, negotiation chats, and CSIRT contacts. Retrieval only — the invoking skill or agent reasons about the result. Note that leak-site claims are claims, not confirmed breaches (see Source reliability below).

When to invoke

  • An investigated domain or organisation should be checked against ransomware leak-site claims
  • Profiling a ransomware group — pull description, TTPs, tools, vulnerabilities, leak-site .onion infrastructure
  • Sector- or country-level ransomware briefing (e.g., "all NL victims claimed in 2026")
  • Detection engineering for a specific group — fetch its public YARA rules + IOC dump
  • Updating the /ransomware-ecosystem knowledge cell with the current top-N groups by victim count
  • Incident response: looking up a country's CSIRT/CERT contact list

Do NOT invoke for:

  • General malware classification — use /lookup-virustotal
  • Confirming whether a specific incident actually occurred — leak-site claims are unverified by default
  • Initial-access vector intelligence — that's not on leak sites; chain /initial-access-brokers instead

How to invoke

Single Python CLI (stdlib only — no install).

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.
