threat-actor-profiling

threat-actor-profiling is a skill for Claude Code from Liberty91LTD/cti-skills. It costs 60 tokens per session (2,660 once invoked), scanned A, original, MIT.

A template and research guide for building a threat-actor profile, a living record of what is known about an attacker or group. It covers names, aliases, attribution, motivation, targets, campaigns, techniques, and infrastructure patterns.

In plain words
What is it for?
Use it to document an actor's identity, affiliations, activity, targets, methods, infrastructure, and intelligence gaps.
Why use it?
It provides a consistent place to collect fragmented information about an attacker and record uncertainty. This makes profiles easier to update and compare over time.

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

threat-actor-profiling 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 1mo 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.

Threat Actor Profiling

A threat actor profile is a living document that consolidates everything known about a threat group. It grows over time as new intelligence is collected.

Sourcing Before Profiling

A profile is built from claims, and each claim belongs to the source that originated it. Before any report feeds the profile:

  1. Resolve provenance. Run /source-provenance on every ingested report or article. Record the primary, the chain and the provenance_basis (platform-resolved, script-resolved or model-judged).
  2. Dedupe by primary, not by URL. Five outlets covering one vendor report are one source. Merge them into a single Sources row for the primary and list the outlets as "via". Count corroboration by independent primaries with separate access only.
  3. Grade per claim. Run /quality-of-information-check on the primary (it calls /claim-extraction). Observations, attribution and assessments from the same report carry different grades. Do not give a report one grade and apply it to everything in it.
  4. Store the grade with the entity. Every TTP row, tooling row, attribution statement and campaign entry carries the primary that supports it and the grade of the supporting claim. When two primaries support the same row, list both and keep the grades separate.

An entity with no resolved primary stays in the profile only with the grade "untraced, tentative" or lower and the note "unresolved provenance". Grades follow the fixed rubric in /quality-of-information-check (references/grading-rubric.md). The grade is two words, access level then claim support, for example "direct, firm". It is not an Admiralty rating.

- **Registrars**: [Preferred domain registrars]
- **TLS patterns**: [Self-signed? Let's Encrypt? Specific CAs?]
- **C2 protocols**: [HTTP/HTTPS, DNS, custom protocols]
- **IP ranges**: [Known IP blocks or ASNs]

### Campaign History
#### [Campaign 1] (YYYY-MM to YYYY-MM)
- **Targets**: [Who was targeted]
- **TTPs**: [Specific techniques used]
- **Outcome**: [Impact, attribution confidence]
- **References**: [Primary reports, each with the grade of the claim it supports]

- **Overlap with**: [Groups that share TTPs or infrastructure]
- **Distinction from**: [Commonly confused groups and how to distinguish]

### Intelligence Gaps
- [What we don't know and need to collect]
- [Specific questions for future collection]

### Sources
One row per primary. Outlets that carried the primary go in "Via".

| Date | Primary source | Via | Access | Access level | Key Contribution |
|------|----------------|-----|--------|--------------|-----------------|
