- scanner.run now persists exposure_state/detail/capabilities for scanned
assets (previously only the index was written).
- Backfill runs a bounded worker pool (16) so it verifies reachable assets
without saturating the DB pool; DB_MAX_CONNS raised for the live test.
- CNAME enrichment queue is now a bounded random sample instead of a FIFO.
The FIFO filled with the first N hostnames seen at startup and dropped the
rest, so CNAME discovery only ever saw stale hostnames; random replacement
gives representative coverage at bounded memory (same fix as the prober).
Verified live:
- all four known-public resources scan + index (DO, AWS s3-<region>, GCS,
Azure container path), 38-1000 objects each.
- backfill of every CT-discovered 'reachable' asset (725) and 'auth_required'
(12) completed with 0 listable: those are MRAP/non-bucket 400s and
list-denied buckets, confirming the checks are actually running.
Readability capabilities (exists/object_readable/listable) are now tracked
separately instead of a single exposure flag, matching how providers differ:
- Azure 'Blob' mode = object readable, not listable; 'Container' = listable
- Cloudflare R2 public URLs are never anonymously listable (root 500); R2 is
object-read only and is no longer probed for listing
- S3/GCS: 200 list = listable; 403 + readable index.html/robots.txt =
object readable only
New columns: cloud_assets.listable, cloud_assets.object_readable.
Azure: account-level container listing is never anonymous; discover containers
by probing a bounded common-name set (or the container from a URL path), then
list blobs.
Classifier: added the legacy AWS '.s3-<region>.amazonaws.com' bucket form.
On-demand scan: POST /api/scan {target} classifies a host or URL, follows CNAME
for custom domains, probes, and indexes readable resources; Azure container
comes from the URL path. UI has a Scan box.
Backfill: POST /api/reprobe re-probes already-discovered assets with the current
checks and indexes any readable ones, recovering findings from earlier probes.
DNS: CNAME-only enrichment (A/AAAA resolved only for matches), 64 workers,
larger queue.
