Surfaces the intrusion-set reverse index from the loaded ATT&CK
bundle: given a technique, returns the list of groups MITRE has
documented as using it. Read-only — explicitly NOT an attribution
claim about a DECNET attacker. The frontend pulls this lazily when
the operator expands a technique panel; payload-size cost on every
TTPTagDetailRow makes embedding wasteful for techniques with 50+
documented groups.
- decnet/web/router/ttp/api_get_groups_for_technique.py exposes
GET /api/v1/ttp/techniques/{technique_id}/groups, response_model
list[GroupRef]. Same JWT-viewer auth gating as the rest of the
TTP router. 404 when the technique_id doesn't resolve in the
bundle.
- Sub-techniques are queried directly (no auto-union with parent)
to match ATT&CK Navigator semantics; callers that want a broader
view query the parent themselves.
- tests/ttp/test_groups_for_technique.py covers happy path, 404,
sub-technique attribution independence, empty-list-on-zero-groups,
and that responses include mitre_url + aliases.
- tests/web/test_api_attackers.py: fix pre-existing fixture drift
introduced by a2a61b63 — three TestGetAttackerDetail cases were
missing AsyncMock for repo.latest_observation_per_primitive,
causing TypeError on await of MagicMock. The new groups endpoint
doesn't share code with attacker_detail; this is a drive-by fix
surfaced by the same suite run.
`for i in $(seq 1 100); do curl -H "X-Forwarded-For: 191.100.20.$i" ...`
was dumping 100 distinct IPs into AttackerDetail's LEAKED IPs row,
drowning the rest of the ORIGIN section. The 100-IP wall is itself a
signal (WAF-bypass-list probing) that deserves a short badge, not a
flood.
Backend:
- get_attacker_ip_leaks gains `limit: int = 10` parameter — caller
only ever needs a sample, not the full set.
- New count_attacker_ip_leaks() returns the unbounded COUNT(*) via
one cheap SQL aggregate.
- Detail endpoint returns {ip_leaks: [first 10], ip_leaks_total: N}
so the UI can render a rotation badge independent of list length.
UI:
- New LeakedIPsRow component. First 5 distinct IPs rendered inline
with hover tooltips (unchanged). When > 5, a `+ N more` expand
button reveals the rest of the sample; when total exceeds the
10-row cap, a subtle `(+M beyond sample)` note appears.
- When total ≥ 20, a red `ROTATION · N` tag renders leading the
row with a tooltip explaining the semantic: "almost certainly
XFF-rotation / WAF-bypass probing, not a real attribution leak."
DB churn is deliberately not capped — 100k rows × ~500 B is tolerable.
If it becomes a problem we can add an ingester-side count-and-skip;
for now the UX fix is the whole story.
Added test_ip_leaks_total_reported_separately_from_list asserting
the endpoint shape matches what the UI consumes.
add_bounty dedups on (attacker_ip, bounty_type, full payload JSON).
Three fingerprint-family bounties (http_useragent, ip_leak,
http_quirks) were including method/path / header_count in their
payloads — fields that vary per request — so a scanner hitting 100
paths produced 100 rows instead of 1, which is what was swelling
AttackerDetail.
Payloads now carry identity-only fields:
- http_useragent: {fingerprint_type, value}. UA + path combinations
no longer collide; one row per distinct User-Agent string.
- ip_leak: {source_ip, real_ip_claim, source_header, headers_seen}.
One row per distinct (proxy source, leaked IP, leaking header)
triple; repeat hits with the same header on different paths dedup.
- http_quirks: {fingerprint_type, order_hash, order, casing_hash,
casing_category, stable_count, tool_guess}. No more header_count
(included volatile headers; Cookie-presence variance broke dedup).
Per-request context (path, method, etc.) was never load-bearing for
analysts — the logs table already answers "when + where" at
per-event resolution. The bounty table is for stable identity.
UI:
- FpHttpQuirks renderer drops the method/path footer line and the
header_count/duplicates tags; shows stable_count instead.
- LEAKED-IPs tooltip on AttackerDetail swaps "X on GET /path" for
"Leaked via X; source 203.0.113.42" — same information, stable.
Tests add a "payload stable across paths and methods" assertion on
http_quirks — locks the contract so a future regression that sneaks
a per-request field back in fails loudly.
Existing duplicate bounty rows don't retroactively collapse.
Dev: `decnet db-reset --i-know-what-im-doing drop-tables` and
restart. Prod: one SQL pass to dedup by (attacker_ip, bounty_type,
payload) — trivial but not automated.
Attackers routinely front their scanners with VPNs/proxies, so the
TCP source we log is the proxy egress, not the real host. But a
surprising number of attacker setups are misconfigured: the proxy
forwards the real IP in an X-Forwarded-For (or Forwarded / X-Real-IP
/ CDN-variant) header. From our side that's a free attribution leak.
New _detect_ip_leak extractor in decnet/web/ingester.py fires at
ingest time per HTTP request. Logic:
1. Require service=http, source_ip present, headers present.
2. If source_ip ∈ DECNET_TRUSTED_PROXIES (comma-separated IPs or
CIDRs) → legitimate reverse-proxy forwarding, skip.
3. Walk proxy-family headers in priority order: Forwarded (RFC 7239)
→ X-Forwarded-For → X-Real-IP → True-Client-IP → CF-Connecting-IP.
4. Extract the left-most parseable IP from the winning header.
5. If that IP differs from the TCP source → emit a bounty with
bounty_type="ip_leak" carrying {source_ip, real_ip_claim,
source_header, headers_seen, path, method}.
Storage is the existing Bounty table — no schema change; de-dup is
handled by Bounty's (attacker_ip, bounty_type, payload_hash) key, so
repeat requests with the same leaked IP don't spam.
AttackerDetail renders a warn-accent "LEAKED IPs:" row under ORIGIN
listing distinct real_ip_claim values; hover tooltip shows the source
header + path of the most recent leak. Only shown when at least one
ip_leak bounty exists.
RFC 7239 Forwarded parser handles the full vocabulary — bare IPv4,
IPv4:port, quoted, IPv6 in brackets, IPv6 with port — returning only
IPs that actually parse.
Closes DEVELOPMENT.md "Network Topology Leakage → X-Forwarded-For
mismatches". Phase 3 of the three-phase Attacker Intelligence series
(phases 1: scanned-vs-interacted, 2: PTR records already shipped).
DECNET_TRUSTED_PROXIES env shape matches THREAT_MODEL DA-08's
"revisit when verified-proxy config lands" note — same token set
future rate-limit work will consume.
Adds a new card on AttackerDetail: SCANNED · N services | INTERACTED
WITH · M services. Distinguishes port-scanners (N high, M=0) from
actual engagement (M>0) at a glance — the analyst's first question
when triaging a new attacker row.
Classifier lives in decnet/correlation/event_kinds.py, a single
source of truth for the event-type vocabulary:
- INTERACTION_EVENT_TYPES — command-family (command/exec/query/...),
SMTP engagement (mail_from/rcpt_to/message_accepted), file/payload
activity (file_captured/upload/download_attempt/retr), pub/sub
(publish/subscribe), recorded TTY sessions.
- NOISE_EVENT_TYPES — DECNET-internal (startup/shutdown/parse_error/
unknown_*).
- Everything else defaults to scan. Conservative by design: new
template verbs show up as "scanned" until explicitly promoted.
Bucket logic: a service is "interacted" if ≥1 of its events
classifies as interaction; otherwise "scanned" if ≥1 scan event;
noise-only services drop. Disjoint by construction.
Deliberate no-schema path: compute on-the-fly in the detail endpoint
via SELECT DISTINCT service, event_type FROM logs. Small result set
(tens of pairs per attacker), cost is trivial vs. the existing
behavior/commands queries. Trade-off: one more DB round-trip per
detail view in exchange for zero ALTER TABLE migration pain and
immediate classifier-change feedback loop.
Profiler's _COMMAND_EVENT_TYPES stays as-is (strict subset of
interactions that carry executable text), with a comment pointing at
the new canonical module.
Closes DEVELOPMENT.md "Attacker Intelligence §Service-Level Behavioral
Profiling — Services actively interacted with".
Groups every flat test_*.py under the module it exercises, matching the
existing tests/{profiler,sniffer,prober,collector,correlation,cli,web,
topology,swarm,bus,updater,api,docker,geoip,...} layout. New folders:
services/, fleet/, config/, logging/, db/ (+ db/mysql/), telemetry/,
mutator/, core/.
Path-dependent __file__ references bumped an extra .parent in three
files that moved one level deeper:
- tests/sniffer/test_sniffer_ja3.py (template path)
- tests/services/test_ssh_capture_emit.py (template path)
- tests/cli/test_mode_gating.py (REPO root)
- tests/web/test_env_lazy_jwt.py (repo var)
Also drops two SQLite runtime artifacts (test_decnet.db-{shm,wal}) that
were leaking into the repo from a previous test run.
Fixes two test_service_isolation cases that patched asyncio.sleep (no
longer on the profiler main-loop hot path — same pre-existing bug I
fixed earlier in test_attacker_worker.py) by patching asyncio.wait_for
and passing interval=0.
