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.
Per-request HTTP fingerprint derived from the header dict we already
log. Captures:
- order_hash: SHA-256 prefix (16 hex) over the lowercased header-name
sequence, minus volatile/per-request headers (Content-Length,
Cookie, Authorization, XFF family, trace IDs). Stable identity for
a given client stack regardless of which target / path is hit.
- casing_hash: same shape but over the per-header casing category
(Title-Case / lower / UPPER / mixed). Attackers frequently spoof
User-Agent but forget their stack sends `user-agent` while browsers
send `User-Agent`.
- tool_guess: prefix match against curl / python-requests /
Go-http-client / nmap-nse signatures. Cheap, best-effort — the
hash is the hard signal.
- duplicates: reserved for when the HTTP template switches from
dict(request.headers) to a list form; today it always fires empty
because dict() collapses duplicates.
Payload is a fingerprint bounty (bounty_type="fingerprint",
fingerprint_type="http_quirks"). Bounty dedup collapses identical
hashes per attacker — one row per distinct fingerprint — so a chatty
scanner doesn't spam the vault, but a tool-chain change from the
same IP surfaces as a new row.
UI renderer (FpHttpQuirks) shows the two hashes, tool guess badge in
violet, casing/count tags, and a collapsible header-order list.
Added to the passiveTypes group so it nests with JA3/JA4L/etc. in
the AttackerDetail fingerprints panel.
One library note: the naive "title-case" classifier failed on tokens
like `X-Forwarded-For` because Python's "".islower() returns False
so `p[1:].islower()` rejects single-letter tokens like the `X`.
Fix: explicitly accept single-char tokens when uppercase.
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.
Resolve each attacker IP's rDNS name once at first sighting, store on
Attacker.ptr_record, render on AttackerDetail under ORIGIN. Many
attackers run infrastructure with forgotten rDNS that instantly
identifies them once surfaced: scan-node-42.shodan.io,
shady-vps.leasecloud.net, etc.
Resolver lives in decnet/geoip/ptr.py — colocated with enrich_ip
because the shape matches (take an IP, return supplementary
metadata, never raise). Uses the OS resolver via socket.gethostbyaddr
offloaded to the default executor, wrapped with asyncio.wait_for
timeout=2s so a slow authoritative NS can't stall the profiler tick.
Profiler side: _WorkerState grows a ptr_attempted: set[str] bounding
resolution to once per worker lifetime. Cold-start batches resolve
concurrently (Semaphore(_PTR_CONCURRENCY=10)) so a backlog doesn't
serialize 2s ceilings. _build_record gains a keyword-only ptr_record
parameter that, when _UNSET, omits the key from the record dict —
upsert_attacker's attribute-merge loop then preserves whatever's
stored on the row. Explicit None is a "fresh failed attempt" signal
and gets written through.
Env kill-switch DECNET_PTR_ENABLED=false for locked-down deploys
where egress DNS is forbidden. Private / loopback / link-local /
multicast / reserved addresses short-circuit before any DNS call.
IPv6 reverse DNS works transparently through the stdlib resolver.
Schema change — run once on upgrade:
ALTER TABLE attackers
ADD COLUMN ptr_record VARCHAR(256) NULL DEFAULT NULL;
Or drop-and-recreate on dev boxes (db-reset's SQLModel.metadata-driven
table discovery now picks it up automatically since ba155b7).
tests/conftest.py disables DECNET_PTR_ENABLED globally for the same
reason it disables DECNET_GEOIP_ENABLED — unit tests must never hit
the network. tests/geoip/test_ptr.py re-enables explicitly via an
autouse fixture.
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".
- Attackers list: small country-code chip next to the IP on each card,
title-tooltip shows the source (e.g. "rir")
- AttackerDetail: country-code tag next to the IP in the header plus an
ORIGIN field in the TIMELINE section for always-visible origin
- TypeScript interfaces updated with country_code/country_source
Adds GET /attackers/{uuid}/smtp-targets (viewer) and GET /attackers/{uuid}/mail
(admin) endpoints, plus two new sections on the attacker detail page:
VICTIM DOMAINS rollup (aggregate-only, federation-gossip-safe) and STORED MAIL
with a drawer that decodes headers, lists attachments, and downloads the raw
.eml via the existing artifact endpoint (?service=smtp).
Replace ad-hoc empty-state markup across Dashboard, TopologyList,
LiveLogs, Attackers, Bounty, AttackerDetail, SwarmHosts, RemoteUpdates
and CommandPalette with the new <EmptyState> component. Themed icons
+ hints improve discoverability; TopologyList and SwarmHosts gain
CTAs to their respective creation flows.
Adds asciinema-player dependency, SessionDrawer.tsx that pages the
transcripts API (500 events per request) and rebuilds a v2 .cast blob
for playback, and a Session Transcripts section in AttackerDetail that
deep-links into the drawer. Truncation banner surfaces the 10 MB
per-session cap when it's been hit.
Adds the server-side wiring and frontend UI to surface files captured
by the SSH honeypot for a given attacker.
- New repository method get_attacker_artifacts (abstract + SQLModel
impl) that joins the attacker's IP to `file_captured` log rows.
- New route GET /attackers/{uuid}/artifacts.
- New router /artifacts/{decky}/{service}/{stored_as} that streams a
quarantined file back to an authenticated viewer.
- AttackerDetail grows an ArtifactDrawer panel with per-file metadata
(sha256, size, orig_path) and a download action.
- ssh service fragment now sets NODE_NAME=decky_name so logs and the
host-side artifacts bind-mount share the same decky identifier.
All info sections (Timeline, Services, Deckies, Commands, Fingerprints)
now have clickable headers with a chevron toggle to expand/collapse
content. Pagination controls in Commands stay clickable without
triggering the collapse. All sections default to open.
Replace flat fingerprint card list with a structured section that
groups fingerprints by type under two categories: Active Probes
(JARM, HASSH, TCP/IP) and Passive Fingerprints (TLS, certificates,
latency, etc.). Each group shows its icon, label, and count.
AttackerDetail: dedicated render components for JARM (hash + target),
HASSHServer (hash, banner, expandable KEX/encryption algorithms), and
TCP/IP stack (TTL, window, MSS as bold stats, DF/SACK/TS as tags,
options order string).
Bounty: add fingerprint field labels and priority keys so prober
bounties display structured rows instead of raw JSON. Add FINGERPRINTS
filter option to the type dropdown.
New GET /attackers/{uuid}/commands?limit=&offset=&service= endpoint
serves commands with server-side pagination and optional service filter.
AttackerDetail frontend fetches commands from this endpoint with
page controls. Service badge filter now drives both the API query
and the local fingerprint filter.
Clicking a service badge in the attacker detail view now filters the
commands and fingerprints sections on that page instead of navigating
away. Click again to clear. Header shows filtered/total counts.
API now accepts ?service=https to filter attackers by targeted service.
Service badges are clickable in both the attacker list and detail views,
navigating to a filtered view. Active filter shows as a dismissable tag.
Migrate Attacker model from IP-based to UUID-based primary key with
auto-migration for old schema. Add GET /attackers (paginated, search,
sort) and GET /attackers/{uuid} API routes. Rewrite Attackers.tsx as
a card grid with full threat info and create AttackerDetail.tsx as a
dedicated detail page with back navigation, stats, commands table,
and fingerprints.
