- stix_custom.py: DecnetActorFingerprintExt (@CustomExtension) wrapping network_behavior (os_guess/hop_distance/tcp_fingerprint/timing_stats/ phase_sequence/behavior_class/beacon fields/tool_guesses) and protocol_fingerprints (ja3_hashes/hassh_hashes/kex_order_raw/ ssh_client_banners/tls_cert_sha256/payload_simhashes/c2_endpoints). XDecnetBehaveProfile (@CustomObject x-decnet-behave-profile) carrying full BEHAVE-SHELL observation envelopes + kd_digraph_simhash. FINGERPRINT_EXT_DEF singleton extension-definition SDO. - Drop legacy flat x_decnet_ja3_hashes / x_decnet_hassh_hashes / x_decnet_c2_endpoints (pre-v1, no consumers). - stix_export: _threat_actor() wired to behavior + observations; build_attacker_bundle/build_fleet_bundle grow observations parameter. - Repo: list_observations_by_attacker + get_all_observations_for_export abstract + sqlmodel impl; all four export endpoints extended. - 18 new tests; inter-DECNET round-trip (stix2.parse → typed objects) is the primary fidelity assertion.

"""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.
