"T1595" alone is opaque; "T1595 — Active Scanning" tells you the
story at a glance. The names come from a backend-side static catalogue
pinned to the same ATT&CK release as the rule engine
(_ATTACK_RELEASE = "v15.1") — names are the canonical MITRE labels,
not author-supplied strings on rules, so a rule author can't typo a
name and the entire fleet sees the typo.
- New `decnet/ttp/attack_catalog.py` with `TECHNIQUE_NAMES` covering
every technique_id + sub_technique_id emitted by `rules/ttp/`
(R0001..R0058 → 69 IDs in the v0 pack).
- `IdentityTechniqueRow` / `TechniqueRollupRow` / `CampaignTechniqueRow`
/ `TTPTagDetailRow` gain optional `technique_name` /
`sub_technique_name` fields. Repo + router populate them from the
catalogue at row-construction time. None when an ID isn't in the
catalogue — UI falls back to the bare ID.
- Coverage test (`tests/ttp/test_attack_catalog.py`) walks every
YAML rule and asserts every emitted ID has a catalogue entry, so
a future rule author who forgets to update the catalogue gets a
loud failure rather than a silent UI fallback.
Frontend:
- `TTPsObservedSection` shows "T1595.002 — Active Scanning:
Vulnerability Scanning" instead of just the ID, with overflow
ellipsis + tooltip for narrow viewports. Inspector header /
TECHNIQUE row also surface the names.
The TTPsObservedSection rollup tells the operator "we saw T1059" but
not why. Click any technique row → side drawer opens listing every
ttp_tag row in scope with the persisted evidence JSON, firing
rule_id / rule_version, source_kind / source_id, confidence, and
created_at. Mirrors the CredentialReuseInspector / BountyInspector
pattern (drawer-backdrop + bd-head/bd-body + kvs grid).
Backend:
- New `GET /api/v1/ttp/tags/by-{scope}/{uuid}/{technique_id}`
(`scope ∈ {identity, attacker, session}`, optional
`?sub_technique_id=`, `?limit=` capped to 1000). Returns raw
TTPTag rows newest-first.
- New `TTPTagDetailRow` Pydantic model + re-export.
- New repo method `list_tags_by_scope_and_technique` on
TTPMixin (+ abstract on BaseRepository) — single query branched
on scope; identity scope projects through `Attacker.identity_id`
the same way `list_techniques_by_identity` does.
- Tests: evidence round-trips, sub_technique filter, JWT-required,
empty scope, unknown scope rejected.
Frontend:
- New `TTPInspector.tsx` + `TTPInspector.css` (violet accent, slide
animation, focus-trapped panel matching the existing inspector
family).
- `TTPsObservedSection`'s TechniqueBar is now click+keyboard
activatable; clicking opens the inspector for that
(technique, sub_technique) tuple.
mypy clean. 532 passed in the targeted sweep.
The TTP worker entry moved out of decnet/cli/workers.py into its own
module so the TTP CLI surface (worker + admin verbs) is colocated,
mirroring decnet/cli/canary.py / webhook.py / swarm.py.
- New `decnet/cli/ttp.py` with `decnet ttp` (worker, ExecStart-stable
for decnet-ttp.service) and `decnet ttp-backfill --since-days N`.
- `decnet ttp-backfill` walks Attacker.commands and CanaryTrigger
history, dispatches each row through the live CompositeTagger,
persists tags via repo.insert_tags (idempotent INSERT OR IGNORE).
--dry-run / --source command|canary|all / --batch-size supported.
- Backfill deliberately bypasses bus publish — historical replay
must not re-trigger SIEM/webhook fan-out per TTP_TAGGING.md
§"Bus topics" loop-prevention invariant.
- Added `iter_attacker_commands_since` / `iter_canary_triggers_since`
read-only iterators on TTPMixin + abstract bindings on
BaseRepository.
- Master-only via gating; both `ttp` and `ttp-backfill` listed in
MASTER_ONLY_COMMANDS.
Add BaseRepository.list_ttp_decky_phases(identity_uuid) returning
per-decky tag observations as (decky_id, tactic, created_at_ts) rows
ordered by creation time. Rewrite from_identity_row() to project
tactic → UKCPhase via tactic_to_ukc_phase and populate the four
phase-handoff maps (first/last_phase_per_decky,
first/last_seen_per_decky) so combined_campaign_weight finally lights
up on real DB rows — not just synthetic fixtures.
ConnectedComponentsCampaignClusterer.tick() pulls each active
identity's per-decky phase observations before projecting features.
Repo failures are non-fatal: a partial repo falls back to the empty
phase-handoff signal (legacy behavior) so the worker stays up.
tests/clustering/test_ttp_phase_handoff.py pins the production-row
pair clearing CAMPAIGN_EDGE_THRESHOLD on a C2 → DISCOVERY hand-off —
the trip-wire that says the whole project paid off.
commands_by_phase_on_decky itself stays empty on the production path:
it is consumed only by the synthetic-fixture similarity surface, and
the phase-handoff edge does not use it. Synthetic fixtures still
populate it directly via from_synthetic_identity.
Dialect-split: portable rollup queries on TTPMixin; bulk insert with
ON CONFLICT DO NOTHING / INSERT IGNORE in the per-dialect repos.
Confidence-floor (< 0.3) drop applied at mixin layer before the
dialect hook. BaseRepository now declares the six TTP methods abstract.
Tests in tests/web/db/test_ttp_repo.py flipped from pytest.fail stubs
to real dual-backend behavioral tests; tests/ttp/test_confidence.py
drop-below-floor xfail removed.
Empty NotImplementedError bodies; the SQL lands at E.3 implementation.
Mixin composed onto SQLModelRepository alongside the existing domain
mixins. Dialect-specific INSERT-OR-IGNORE syntax overrides land in
the per-backend subclasses at E.3 per the dual-DB-backend convention.
