"""GET /api/v1/attackers/{uuid}/export/stix — STIX 2.1 bundle for one attacker.
|
|
|
|
Returns a self-contained STIX 2.1 Bundle with the attacker's IP
|
|
observation, ATT&CK technique usage (attack-patterns + uses
|
|
relationships + per-tag sightings), captured artifacts (files),
|
|
SMTP targets, and provider intel summary (note). All SDOs are signed
|
|
under a stable DECNET org Identity.
|
|
|
|
Attack-pattern SDOs carry the canonical MITRE STIX IDs so the bundle
|
|
is deduplicated by consumers who already have the public ATT&CK bundle.
