indicator-pivoting

indicator-pivoting is a skill for Claude Code from Liberty91LTD/cti-skills. It costs 103 tokens per session (6,359 once invoked), scanned A, original, MIT.

A threat-intelligence method for using one known indicator—such as an IP address, domain, file hash, or URL—to find related infrastructure. It treats the investigation as a graph of connected indicators.

In plain words
What is it for?
Use it to choose the next lookup based on the indicator type, walk through connected results, score sources, apply handling labels, and express confidence in the findings.
Why use it?
A single indicator often reveals only part of an attack or campaign. Pivoting helps expand the investigation through related technical evidence and then assess its reliability.

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

indicator-pivoting 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.

Indicator Pivoting

Pivoting is the art of using one known indicator to discover related infrastructure, expanding a single seed into an understanding of an adversary's wider operations. Each pivot is a directed-graph walk: the node is an indicator (typed), the edge is a relation derived from a lookup, and the cost is one or more API calls plus the analyst time to interpret the result.

This skill is the canonical "how to walk the IOC graph" reference. The four investigation skills (/ip-investigation, /domain-investigation, /hash-investigation, /url-investigation) chain a fixed set of lookups for a known seed type; this skill takes over when you need to keep walking past their first-hop output.

This skill invokes: /lookup-liberty91, /lookup-virustotal, /lookup-otx, /lookup-shodan, /lookup-censys, /lookup-urlscan, /lookup-abuseipdb, /lookup-greynoise, /lookup-misp, /lookup-opencti, /lookup-ransomwarelive, /lookup-crowdstrike, /lookup-reversinglabs; then /score-source, /apply-tlp, /confidence-language. May hand off to /threat-actor-profiling, /campaign-tracking, /malware-analysis, /yara-writing, /sigma-writing, /darkweb-collection.

When to invoke

  • The user has a single seed IOC and asks "what else is related to this?"
  • An investigation skill returned pivot_candidates and you need to walk further than its routing did
  • You suspect a campaign cluster (multiple indicators in incident telemetry) and want to confirm common infrastructure
  • A threat-actor profile mentions an indicator and you want to see the wider footprint
  • You need to clearly document a pivot chain so a reviewer can trace your reasoning end-to-end

Pivot decision trees, with the commands to run

For each starting indicator type: a tree of pivots, then the concrete commands. The /lookup-* form is the skill-invocation; the python3 tools/clis/... form is the underlying CLI. Both are equivalent — pick whichever the surrounding context demands.

indicator-pivoting is a skill published in the GitHub repository Liberty91LTD/cti-skills (18 stars, last pushed 1mo ago), licensed MIT. It adds 103 tokens to every session and 6,359 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
