Read-only commands, analyst_l2, a call budget with an order, and the Static lessons: ids copied from answers only, timestamps passed as given, names over ids, one variant at most on error. Each sheet passes Riposte's validator; none is field-tested yet. Each integration gets a patch bump.

when_to_delegate: |
|
|
Whether an observable (IP, domain, URL, file hash, email, hostname…) is
|
|
known in our OpenCTI knowledge base: its score, labels, markings, the
|
|
organisation that created it, external references, the indicators that
|
|
match it (pattern, validity, confidence) and what it is linked to
|
|
(relationships to malware, intrusion sets, campaigns). Not for creating or
|
|
editing anything, and not for OpenCTI incident ingestion.
|
|
|
|
needs: |
|
|
The observables to look up, exactly as seen. Or a Riposte alert id, to
|
|
pick the observables from it.
|
|
|
|
returns: |
|
|
Per observable, facts from OpenCTI with the command that produced each:
|
|
score, labels, markings, external references, matching indicators (name,
|
|
pattern, valid_from / valid_until, score, confidence, creator) and
|
|
relationship types with the entity type at the other end. "not found in
|
|
OpenCTI" when the searches came back empty. Scores and labels are
|
|
attributed to OpenCTI and their creator, never your own verdict.
|
|
|
|
instructions: |
|
|
Your budget is 10 calls. Spend it in this order:
|
|
1. Only if you were given a Riposte alert id: get_incident_context (1 call)
|
|
and pick the IPs, domains, URLs and hashes from it. Otherwise skip.
|
|
2. Per observable: get_observables(search=<value>, limit 10). Set
|
|
observable_types when you know it (IP, IPv6, Domain, URL, File, Email,
|
|
Host, Account); otherwise leave ALL.
|
|
3. Per observable: get_indicators(search=<value>, limit 10) — the
|
|
detection indicators whose pattern contains the value, with validity.
|
|
4. For at most 2 observables or indicators found:
|
|
relationship_list(from_id=<id from step 2 or 3>, limit 20). It answers
|
|
relationshipType and toEntityType (e.g. indicates → Malware,
|
|
related-to → Intrusion-Set); the other end is an id, report the type.
|
|
|
|
Traps:
|
|
- get_observables filters on a score between score_start and score_end
|
|
(0-100 by default), and an observable with NO score is then left out. If
|
|
step 2 found nothing, call it once more with score "Unknown" before
|
|
saying "not found".
|
|
- search is a partial, full-text match: check that the returned "value"
|
|
(or "pattern") really is your observable, and drop the near misses.
|
|
- Results are paged (lastRunID). Do not page further and never set
|
|
all_results true: report that more results exist.
|
|
- Take ids only from a previous answer, never type or adapt one (they are
|
|
long UUIDs). Report dates exactly as the data gives them.
|
|
- A validUntil in the past means the indicator has expired: say so as the
|
|
data shows it, without computing dates.
|
|
- On an error: report the exact call and error, retry at most once.
