Concelier Connector Research – 2025-10-11

Snapshot of direct network checks performed on 2025-10-11 (UTC) for the national/vendor connectors in scope. Use alongside each module’s TASKS.md notes.

ACSC (Australia)

• Enumerated feed slugs /acsc/view-all-content/{alerts,advisories,news,publications,threats}/rss; every endpoint negotiates HTTP/2 then aborts with INTERNAL_ERROR (curl exit 92). Forcing HTTP/1.1 hangs >600 s and sitemap/HTML fetches fail the same way.
• Next actions: prototype SocketsHttpHandler settings (RequestVersionOrLower, allow fallback to relay), capture successful headers from partner vantage (need retention + cache semantics), and keep FEEDCONN-SHARED-HTTP2-001 open for downgrade work.

CCCS (Canada)

• JSON endpoint (https://www.cyber.gc.ca/api/cccs/threats/v1/get?lang=<lang>&content_type=cccs_threat) returns ~5 100 records per language; page=<n> still works for segmented pulls and the earliest date_created seen is 2018‑06‑08 (EN) / 2018‑06‑08 (FR). Use an explicit User-Agent to avoid 403 responses.
• Follow-up: telemetry, sanitiser coverage, and backfill procedures are documented in docs/ops/concelier-cccs-operations.md (2025‑10‑15). Adjust maxEntriesPerFetch when performing historical sweeps so cursor state remains responsive.

CERT-Bund (Germany)

• https://wid.cert-bund.de/content/public/securityAdvisory/rss responds 200 without cookies (≈250-item window, German taxonomy). Detail links load an Angular SPA that fetches JSON behind the bootstrap session.
• Confirmed GET https://wid.cert-bund.de/portal/api/securityadvisory?name=<WID-SEC-…> returns JSON once the portal cookie container is primed; payload includes severity, CVEs, products, and references used by the connector fixtures.
• Historical advisories accessible through the SPA search/export endpoints once the XSRF-TOKEN cookie (exposed via GET /portal/api/security/csrf) is supplied with the X-XSRF-TOKEN header:
  • POST /portal/api/securityadvisory/search ({"page":N,"size":100,"sort":["published,desc"]}) pages data back to 2014.
  • GET /portal/api/securityadvisory/export?format=json&from=YYYY-MM-DD emits JSON bundles suitable for Offline Kit mirrors.
• Locale note: content is German-only; Concelier preserves language=de and Docs will publish a CERT-Bund glossary so operators can bridge terminology without machine translation.

KISA / KNVD (Korea)

• https://knvd.krcert.or.kr/rss/securityInfo.do and /rss/securityNotice.do return UTF-8 RSS (10-item window) with detailDos.do?IDX= links. No cookies required for feed fetch.
• Detail SPA calls resolve to rssDetailData.do?IDX= JSON payloads; connector fetches those directly, sanitises HTML, and records Hangul metadata (NFC). See docs/dev/kisa_connector_notes.md for telemetry + localisation guidance.

BDU (Russia / FSTEC)

• Candidate endpoints (https://bdu.fstec.ru/component/rsform/form/7-bdu?format=xml/json) return 403/404; TLS chain requires Russian Trusted Sub CA and WAF expects additional headers.
• Next actions: acquire official PEM chain, point concelier:httpClients:source.bdu:trustedRootPaths (or concelier:sources:bdu:http:trustedRootPaths) at the Offline Kit PEM, keep allowInvalidCertificates=false, script session bootstrap, then capture RSS/HTML schema for parser work.

NKTsKI / cert.gov.ru (Russia)

• https://cert.gov.ru/rss/advisories.xml served via Bitrix returns 403/404 even with Accept-Language: ru-RU; TLS chain also requires Russian trust anchors.
• Next actions: source trust store, configure concelier:httpClients:source.nkcki:trustedRootPaths (Offline Kit root via concelier:offline:root), prepare proxy fallback, and once accessible document taxonomy/retention plus attachment handling.

CISA ICS (United States)

• curl -I https://www.cisa.gov/cybersecurity-advisories/ics-advisories.xml returns HTTP 403 + x-reference-error (Akamai). Same for legacy feed paths.
• Next actions: secure GovDelivery access, document token rotation, and build HTML/email fallback with throttling.

Cisco PSIRT

• https://api.cisco.com/security/advisories/latest returns ERR_596_SERVICE_NOT_FOUND when unauthenticated. openVuln REST requires Mashery OAuth (client credentials) with quotas ~5 req/s, 30/min, 5 000/day; supports pageIndex/pageSize pagination.
• Next actions: register OAuth app, capture pagination/delta parameters, and compare API vs RSS coverage.

Microsoft MSRC

• REST endpoint (https://api.msrc.microsoft.com/sug/v2.0/en-US/vulnerabilities) requires Azure AD token + api-version (current 2024-08-01) and supports delta filters (lastModifiedStartDateTime). CVRF ZIP remains available for offline use.
• Next actions: finalise AAD app registration, implement token cache, and design combined REST+CVRF ingestion path for determinism.
